Calculating the amount of electricity consumed by your welding machine or, in fact, any machine is very easy. You need simple math and very little information to calculate it. In this article, we will exactly look at how much electricity a welding machine consumes and how we can calculate it.

Generally, a normal welding machine uses 4-12 kilowatts per hour. And on average a welding session can take up to 15 – 20 minutes. Assuming those values, a welding machine could consume between 66 and 200 watts per minute. Based on the amount of work you do, you can easily calculate your monthly electricity consumption.

I can imagine that perhaps the technical details of how this works would be confusing to you. Because before you can calculate the amount of power that your welding machine uses, there are a few other things that you need to make sure you take care of.

In the following paragraphs, I will not only demonstrate how you can calculate the amount of power your welding machine uses but also how you can calculate the cost of the power that it uses.

How to Calculate the Electricity Consumption of Your Welding Machine

There are 3 different methods that you can use to calculate the amount of electricity that your welding machine consumes, and they are as follows:

So let’s look at these methods one by one.

Method 1:  Manual Calculation

You will need to have 3 things in order to calculate the amount of electricity that your welding machine consumes.

  • The Watt power of your welding machine
  • The average duration of your welding session
  • How many sessions do you typically weld in 1 month

Therefore, for the sake of understanding, we will assume these three values; however, you will need to replace these values with ones that are appropriate for your circumstances and the kind of welding machine you use.

Let’s Assume:

Welding Machine Power = 4 kilowatt-hours (4000 watt-hours)

Welding Session Duration = 20 minutes.

Number of Sessions per Month = 150

We can calculate the electricity consumption per session:

Watts per Session = Welding Machine Power (kWh) * (Welding Sessions Duration / 60)

Note: To convert from minutes to hours, divide the session duration by 60. But if you are using session duration in hours then you don’t have to do this.

Now replace the values in the formula:

Watts per Session = 4 * (20/60) = 1.33 kWh

Now that we know how much electricity is used during a single welding session, we can easily calculate the amount of electricity used throughout the entire month based on the total number of welding sessions that occur during a given month:

Electricity Consumed per Month = Watts Per Session * Number of Sessions per Month

Note: The number of welding sessions completely depends on the work that needs to be done. You can make a rough estimate of how many sessions you take each day, multiply that number by 30, and that will give you the total number of sessions you take each month.

Now replace the values in the formula:

Electricity Consumed per Month = 1.33 kWh * 150 = 200 kWh (according to assumed values).

If you want to take these calculations to the next level, you can calculate the cost of your electricity by using the following formula:

Electricity Cost for One Month = Electricity Consumed per Month * Electricity Cost for 1kWh

Let’s assume:

Electricity Cost for 1 kWh = $0.8

So,

Electricity Cost for One Month = 200 kWh * $0.8 = $160.

I understand that it seems expensive, but keep in mind that we made some assumptions about some of the values; consequently, it’s possible that in your situation it won’t be that pricey.

In general, welding is not an expensive process, and if you do it right, you can easily make a good deal of profit from it. Welding has provided a means of subsistence for many people for a significant amount of time.

How Much Power Does a 220v Welder Use?

The 220v welding machine requires 5,500 running watts and 8,000 peak watts to operate at full power. However, you must be aware that there are many different brands of welding machines, and that each brand has its own set of specifications that are unique to that brand. The activity of a large welding machine will require a greater number of watts than that of a smaller one.

Reasons Why your Welding Machine is Consuming too much Power

Here are some reasons why your welding machine consumes too much energy:

1. Too Much Arc Time

The arc time is the amount of time the arc stays on. Too long an arc time can cause a lot of heat and energy consumption, so it’s important that you check your arch time and make sure it’s not too long.

2. Faulty Cables

If you have defective wires, they can cause more electricity loss and also lead to high consumption. The most common reasons for this problem are:

  • The wire joint is not tight enough or has become loose over time;
  • The insulation of the cable has deteriorated due to exposure to heat and moisture;

3. Using an Electrode with a Thick Coating

You can reduce the consumption of electricity by using an electrode with a thin coat. The thicker the coat, the more resistance you will have to the arc and therefore require more energy to heat up your welding machine. When you are using a thicker coating on your electrodes, it may also cause some problems with the stability of an arc in general.

4. Too Much Electrical Resistance

Electrical resistance is caused by the flow of electrons in a conductor. The higher the electrical resistance, the more energy is lost as heat. This can be caused by joints in wire or poor welding techniques. The more joints you have in your cable, the higher your electrical resistance will be, and therefore it will consume more power to produce the same amount of heat.

5. Incorrect Welding Polarity Settings

If you’re using a welding machine and the polarity settings are incorrect, this can cause your energy to be lost. This is especially true if you are working with AC or DC welding machines that have different voltage requirements. In order to prevent this from happening, it’s important to know what type of welding you’re doing so that your polarity setting is correct before starting any work on your project.

6. Incorrect Amperage Settings

Be sure to use the appropriate amperage for the kind of metal you are working with, as failure to do so might result in difficulties with the consumption of an excessive amount of power. The proper setting for an amperage range should be dependent on the material that you are working with.

How to Improve Welding Efficiency?

Here are a few of the tips that will help you increase your welding efficiency and thus help you reduce your electricity cost:

  • Reduce Cable Length Voltage Drops
  • Choose the Optimized Drive Roll
  • Proper Drive Roll Tension
  • Effectively Manage Dirty Power

Tip 1: Reduce Cable Length Voltage Drops

Managing the voltage drop that can occur in weld cables is a common problem in the welding process. Resistance in the welding circuit causes voltage drops due to factors such as distance, number of connections, and corrosion. To minimize power loss, use shorter wires if at all possible.

Tip 2: Choose the Optimized Drive Roll

Taking the wire diameter and gauge into account can help you decide on the right size and kind of drive roll. Because of its flexibility, tubular wire demands a knurled drive roll, which has teeth to hold the wire and help in its advancement.

To avoid snagging, a drive roll with a smooth V-groove and solid wire should be used. Consistent wire feeding is facilitated by periodically exchanging the driving roll with one that is more suited to the wire being fed.

Tip 3: Proper Drive Roll Tension

Every time you swap out your drive roll, you need to make sure the tension is adjusted correctly. The wire may slide if the tension is too low. Liner failure may cause arc instability, birdnesting, and burnback if the insulation is compromised. Clean the liners by forcing compressed air through them to blow out any dust or debris. If a clog is observed, the liner must be replaced immediately.

Tip 4: Effectively Manage Dirty Power

Welding equipment is vulnerable to “dirty power” when inconsistent main power is used to power it. On the construction site, portable generators may be a source of polluted electricity. The power efficiency of modern welding power sources is much higher than that of older methods. Some bigger engine-driven welders/generators may provide electricity to as many as six smaller welders simultaneously.

Takeaway

It is my sincere hope that you will find the information presented here to be of use in identifying the root of the issue with your power usage and formulating a plan to address it.

Your profitability will increase as a direct consequence of an increase in your welding efficiency, an improvement in the quality of the weld beads you produce, and the capacity of your welding equipment to take advantage of lower electricity prices.

Any welding operation that you perform puts you and anyone else in the area in danger of a number of different things. As a result, it is completely reasonable for you to be concerned about preventing your hair from becoming entangled in any welding equipment and posing a threat to your health. In this article, I will talk about how you can safely weld if you have long hair.

If you want to weld while having long hair, a French braid is the best option for keeping your hair together. This will help you in tying your hair and hold it together behind your neck. The French braid should keep the hair compact and close to your head’s shape, and it also allows you to wear a welding helmet. As a result, you will be able to wear full safety equipment.

When you are dealing with hot weld spatters, having long hair can present a particularly difficult challenge. Therefore, if you are interested in learning more about how you can safely weld with long hair, continue reading the rest of this article, where I will discuss the topic in greater detail and share some helpful hints.

How Your Long Hair Can be an Issue While Welding?

Welding procedures, as I indicated earlier, expose the operator as well as anybody else in the vicinity of the workplace to a wide variety of risks. A project involving welding presents a number of potential dangers and threats; it is important that you be aware of these issues in order to protect not only yourself but also others around you. Especially when dealing with spatters, it is easy for things to go wrong if you have long hair.

Before we look at all of the tips you may weld with long hair, we need to first understand the potential risks you run and everything that might go wrong. Long hair poses a unique set of challenges when it comes to welding. A few are mentioned below:

  • Spatters are your hair’s worst enemy.
  • UV rays can permanently damage your hair.
  • With long hair, grinders can cause serious accidents.

Let’s look at these problems one by one:

1. Take Spatters Seriously 

The spatter, sparks, and heat generated by the arc provides the greatest challenge throughout the welding process since they may travel up to 35 feet and enter any nearby place. You will want to provide enough protection for your long hair if you are going to be in an atmosphere like this.

Not just your hair, but everything else that might catch fire should be kept at least 35 feet away from the welding location. In addition, a fire extinguisher should never be far away. In the event that a fire breaks out.

2. UV Rays Can Damage Your Hair Permanently

Molten metals, welding arcs, and ultraviolet radiation will be present in the work environment while welding is being done. The interaction of all these factors puts you at an increased risk of serious burns. The actual welding arc may reach temperatures of up to 10,000 degrees Fahrenheit, making it one of the hottest processes possible.

And believe me when I say that you do not want that welding arc to get anywhere near your hair. Your hair will suffer a significant amount of damage as a result, and it is possible that it could even be burned.

3. Grinder Can Give You Nightmares

The usage of grinders is another factor that may create issues for your lengthy hair. Using grinders and welding go hand in hand when working with metals. Therefore, if you are a welder, you will most likely make extensive use of the grinder. And grinders are really your worst enemy when it comes to your long hair.

When you’re working, you can find yourself crouching over a grinder, which can cause serious accidents if you don’t protect your hair properly.

Tips from a Pro Welder to Protect Your Long Hair When Welding

Now you know what the most obvious dangers that you have when welding with long hair. The next step is to tell you how you can keep yourself safe from those dangers.

Here are a few of the tips that you can consider:

  • Braid your hair while welding
  • Put your hair in a tight knot behind your neck
  • Consider buying a welding cap
  • You can use a bandana too if you are a bandana lover

Let’s discuss these tips one by one:

Braid hair woman welding

1. Braiding is the Best Option You Have

Welding hoods, helmets, or shields will provide the optimum amount of protection from any sparks, heat, UV rays, flash burns, or infrared light that may be present. They will protect not only your face and neck but also your eyes and hair. As a result, I feel that acquiring one is the best approach to protecting oneself.

Welding hoods are often made of cotton or leather and are rather light in weight and can go easily along with helmets. Make sure that whichever helmet you decide to purchase, is not too heavy and that it is comfortable to wear. It must also include a spatter barrier, the ability to be modified, a sensor bar, and the availability of replacement components.

2. You Can Simply Put Your Hair in a Tigh Knot

The most conventional and easiest technique for a welder operator to keep their long hair out of their face is to pull it back into a tight bun. Wrap an elastic band over your buns and secure them in place to prevent them from falling on your face.

If there are any unruly hairs, just use bobby pins to push them up and you should be OK. Anything that prevents your hair from falling on your face will suffice.

3. Consider Buying a Welding Cap

A welding cap is a good option if you want something that is both lightweight and comfortable. It must adequately shield your head from any hot metal, sparks, or splatters that may be present.

Not only they are effective in protecting your hair, but they are also made completely of cotton, making them incredibly breathable and also preventing sweat from pouring down your eyebrows while working.

4. Bandana is Another Option That You Can Use

Braids are not easy to create for everyone, and they may even be difficult to perform on a regular basis. If you don’t know how to braid my easiest suggestion would be to put a bandana over your head and tuck all of your hair within.

When welding, sparks will fly everywhere, and this will keep you safe. Make use of bobby pins or a bun to tuck in all of the ends. Bandanas aren’t my first choice for headgear. But it works. It’s a good option to have in case you don’t know how to braid your hair.

Few Other Safety Measures That You Need to Take

In addition to your hair, there are a few other parts of your body that need your attention. Some of these essential measures for ensuring your safety are listed below:

  • Protect your eyes at all cost
  • Always keep a fire extinguisher in your shop
  • Wear protective clothing
  • Make habit of using respirators
  • Beware of leakages in your welding system
  • Keep your welding space clean

Let’s discuss them one by one:

1. Protect your eyes at all cost

Be sure to always wear safety glasses in your workplace to protect your eyes from flying debris, which is often composed of metal. If you routinely do welding tasks, you will be exposed to a significant amount of flying debris.

You should make it a routine to put them on as soon as you come in the door; this will ensure that you are protected at all times.

2. Always keep a fire extinguisher in your shop

You shouldn’t be shocked if anything catches fire at some time during a welding operation because of all of the intense heat and sparks that are produced throughout the process. Because fires are a very real risk, you should always have an extinguisher on hand in case one breaks out.

3. Wear protective clothing

If you’ve ever imagined yourself beginning your first welding project in a pair of shorts, an old t-shirt, and a pair of flip-flops, you should rethink that idea. Wearing the necessary protective clothing at all times when welding is required if you wish to prevent injuries to your body, notably burns, that may be caused by the process.

4. Make habit of using respirators

You should always wear a respirator if you are going to be dealing with metals or any other materials that have the potential to emit harmful vapors.

Welding or cutting certain materials may produce a welding plume, which is a combination of hazardous gases, fumes, and smoke. This is not the type of thing you want to breathe in if you want to keep your lungs healthy and prevent respiratory issues.

If you are interested in knowing more about respirators and their types, please check out my other article.

5. Beware of leakages in your welding system

There is a good chance that you have pressurized containers in your welding shop that hold liquids or gases. Take extra precautions to check that none of those containers or the items that you are attaching to them have any leaks in them.

See my other article to know more about leakages and how to detect them.

6. Maintain your equipment

If you want to establish the safest possible working environment for your welding projects, you need to give your equipment a lot of TLC and make sure it’s in good operating order at all times. If your welding equipment and tools are in disrepair, an accident is almost waiting to happen every time you use them. However, the vast majority of incidents of this kind are avoidable if proper care is taken with the equipment.

Wrapping it Up

When it comes to welding, safety is the most important thing to keep in mind at all times. Because because welding involves a significant amount of fire and spatters, it is essential that you take a significant amount of precaution to protect your hair. I really hope that you’ll be able to keep your hair under control while welding thanks to the advice that’s been provided in this article.

Welding is joining two pieces of metal together by melting and cooling them until they become one piece. Welding processes include:

  • Oxyacetylene welding
  • Shielded metal arc welding (Stick)
  • Gas tungsten arc welding (TIG)
  • Gas metal arc welding (MIG)
  • Flux-cored arc welding
  • Torch or oxyfuel brazing

Some methods employ both heat and pressure, while others employ only heat. Welding is commonly used to construct automobiles, airplanes, and buildings. Other metal-cutting methods, such as oxy-acetylene and plasma arc cutting, use heat or electricity to cut through metal.

1. Oxyacetylene welding

Oxyacetylene welding (OAW) is a method of joining two pieces of metal using heat generated by the combustion of oxygen and acetylene gas.

Torch brazing (TB) is similar, but the metal is not completely melted. Instead, a special alloy is melted and used to join the two metal pieces.

Oxyfuel gas cutting (OFC) is a method of cutting metal that uses the same tools and gases as OAW and TB.

To generate heat and bond the metal, all of these methods employ a torch and special gases. They are frequently used on small or thin metal pieces.

Applications:

  • Welding and brazing thin or small pieces of metal
  • Welding and brazing dissimilar metals
  • Cutting and piercing metal

Situations to Avoid:

  • Welding thick or heavy sections of metal
  • Welding high alloy or stainless steel
  • Welding in high wind or outdoor conditions (due to the open flame)
  • Welding in confined spaces (due to the production of harmful gases)

2. Shielded metal arc welding (Stick)

Shielded metal arc welding, or SMAW, is a way of welding metal together using an electrode that is coated with a special kind of flux.

The electrode melts and becomes a part of the welded metal. To do SMAW welding, you need a transformer, two welding cables, a work clamp, and an electrode holder.

There are many different types of electrodes you can use for SMAW welding, so you can choose the one that is best for your project. With SMAW welding, you can join different types and thicknesses of metal using the same machine.

Applications:

  • Welding thick or heavy sections of metal
  • Welding in outdoor conditions
  • Welding in dirty or contaminated environments
  • Welding on dirty or painted surfaces

Situations to Avoid:

  • Welding thin or small pieces of metal (more suited for TIG welding)
  • Welding high alloy or stainless steel (can affect the quality of the weld)
  • Welding in confined spaces (due to the production of harmful gases)
  • Welding in the presence of high winds (due to the electric arc)

3. Gas tungsten arc welding

GTAW, or gas tungsten arc welding, is a method of joining metal using a tungsten electrode. The tungsten electrode generates an electric arc, which melts the metal being welded as well as the end of the filler metal, which is manually applied.

Shielding gas is emitted from the welding gun to protect the molten weld metal from dirt and other contaminants. A foot or thumb switch can be added to the GTAW equipment to help the welder better control the welding.

GTAW welding produces very clean, high-quality welds, but it is slower and requires more skill than other welding methods. It is particularly useful for joining metal alloys that can only be joined with GTAW.

Applications:

  • Welding thin or small pieces of metal
  • Welding high alloy or stainless steel
  • Welding in outdoor conditions (with proper shielding gas)
  • Welding materials with high levels of contaminants or impurities
  • Welding in high-precision environments

Situations to Avoid:

  • Welding thick or heavy sections of metal (more suited for MIG welding)
  • Welding in high production environments (slower process)
  • Welding in confined spaces (due to the production of harmful gases)
  • Welding in the presence of high winds (due to the electric arc)

4. Gas metal arc welding (MIG)

Mig welding is a type of arc welding that uses a continuously supplied wire electrode and gas to weld metal together.

It is becoming more popular because it is easier to learn than other types of welding, like stick and tig welding, and it is faster because you don’t have to stop and change the electrode as often.

Mig welding also creates less slag and spatter, which makes it more enjoyable to use and easier to clean up.

However, MIG welding equipment is more expensive and the MIG gun, which is the portable part of the equipment, can be difficult to use in small spaces. Mig welding also requires a shielding gas to work, so it is not as good for outdoor use.

Applications:

  • Welding thick or heavy sections of metal
  • Welding high alloy or stainless steel
  • Welding in high-production environments
  • Welding in outdoor conditions (with proper shielding gas)

Situations to Avoid:

  • Welding thin or small pieces of metal (more suited for TIG welding)
  • Welding in confined spaces (due to the production of harmful gases)
  • Welding in the presence of high winds (due to the electric arc)
  • Welding materials with high levels of contaminants or impurities (can affect the quality of the weld)

5. Flux-cored arc welding

Flux-cored arc welding, or FCAW, is a method of joining metal using a special type of electrode wire known as a flux core wire.

The wire is fed from a spool continuously through the welding equipment and out of the gun. The welding current flows through the equipment, melting the wire and the base metal.

Some flux core wires generate their own shielding gas as they melt, while others require the use of additional shielding gas. As the wire melts, it produces a gaseous cloud that shields the weld surface and removes impurities from the molten metal.

After the weld is completed, a layer of slag must be removed from the weld’s top. Despite this additional step, FCAW is a popular welding technique because it produces high-quality welds quickly and is very versatile.

FCAW equipment is similar to that used in gas metal arc welding (GMAW), and both methods are semiautomatic, which means that the wire is fed automatically but the welder moves the gun manually. Welding supply stores and other retailers stock FCAW equipment and filler metals.

Applications:

  • Welding thick or heavy sections of metal
  • Welding in outdoor conditions (with proper shielding gas)
  • Welding in high-production environments
  • Welding in dirty or contaminated environments

Situations to Avoid:

  • Welding thin or small pieces of metal (more suited for TIG welding)
  • Welding high alloy or stainless steel (can affect the quality of the weld)
  • Welding in confined spaces (due to the production of harmful gases)
  • Welding in the presence of high winds (due to the electric arc)
