How To Wire A 220 Outlet For A Welder

What’s The Difficult Part Of This Process And How Safe It Is?

The crucial part of wiring a 220 outlet for a welder is snapping a wire into the gang box. It is essential to ensure that the package doesn’t have any power supply running because a heavy running power supply can electrocute you. The process requires precision and a good hand to ensure that wires are properly screwed and connected to the ground wire.

While it may seem easy to connect the wire correctly to the gang box and the ground wire, it requires accuracy when pulling out 6 inches of plastic of the wire by cable ripper to screw it inside the gang box. You might find difficulty in doing this process if you don’t have a stable hand. Also, it is very important to wear all the safety gear during the entire process. 

Doing an electrical installation can be risky, especially when you’re not a professional and do not have proper knowledge about the field. The reason for being dealt with electrical equipment with a heavy running supply can lead to an electrical shock that might result in paralysis or even death in worst-case scenarios.

Similarly, wiring a 220 outlet for a welder can be dangerous when not taken care of and following instructions while operating the welder. It is essential to switch off the breaker box when starting the process and not touch any metal object before it is turned off. Also, it is recommended to buy heavy quality equipment as this wiring draws a heavy electric supply. 

The process can be difficult and unsafe if you’re not a trained electrician. It is recommended to do proper research before starting to wire. However, if you’re confident in handling electrical equipment and are trained for the job perfectly, you can start wiring without delay. 

Do I Need An Adapter For This Process?

A welding adapter is required for safe installations of a higher degree of connections in hygienic or industrial applications. It ensures that the application is perfectly sealed with high-pressure resistance. It is used also for connecting to the outlet 220V with the appliances when both have different plug shapes. Then, there is a need for a quick adapter for the functioning of a 220 outlet.

But for the process of wiring a 220 outlet for welders, an adapter is not necessary for normal circumstances because you can easily do wiring through it in your home. However, if you have any of the above-mentioned requirements, then one can be bought.

Do I Need To Take Safety Measures In The Process?

If you’re planning to do the process without any assistance, it is necessary to follow certain safety measures while operating. First of all, when you’re starting with the wiring, make sure that the breaker is turned off before operating. It is very important to ensure that the circuit breaker is not functioning and the box has no power supply. Also, the metal parts shouldn’t be touched before switching off the circuit.

Make sure you use electrically insulated gloves like these value-for-money ones or you can use these high-end ones if you face frequently the risk of electrocution. In addition, you need to have electrically insulated boots. Possibly the best boots that have this insulation along with being waterproof, durable, and having a hard toe are these top-rated boots.

A welder should wear safety gear like welding helmets and gloves, apart from following the measures. Additionally, safety glasses should be worn to protect your eyes against any hazardous material. It is important to follow every safety measure before you start wiring.

What Size Of Breaker Is Required For A 220V Welder?

 Circuit breakers are required depending on the amount of electric current a device requires to operate. The correct size of the circuit breaker is essential to understand the welding machine as well as the electric current needed. For example, a device that requires a 27 amp electric current would need a circuit breaker that is 30 amps.

However, the wire used for wiring a circuit breaker should also adjust the specific electric current passed by the breaker. In the same way, a 20 amps breaker would require at least a 12-gauge wire. So, it depends on the electric current and the wire when deciding the breaker’s right size for your welder.

Therefore, for a 220V welder, the circuit breaker requirement would also depend on the degree of electric current in the amperage it will operate at. We can say for 220V welders that a circuit breaker with a current ranging from 30 to 40 amps is enough for sustainable wiring. You can start searching for the right circuit breaker for your case here. A 220V welder with 50 amps circuit breaker can be effectively used for phase 3 works like running small businesses or welding around your farm.

Also, for the functioning of a 200V welder for heavy-duty work, a three-prong or four-prong outlet is recommended. It ensures smooth working. It is very much required to buy the breaker’s right size for your 220V welding purposes because an overloaded breaker can be very hazardous. It can not only lead to electrocution danger but also cause a fire explosion. Moreover, it can damage your expensive electrical equipment and cause a problem in future use.

Thus, it is essential to search for your welding process for a suitable circuit breaker that is highly rated and durable as well online or through a local hardware shop.

Process Of Wiring A 220 Outlet For Welder

Phase 1: Equipment Required

Before you start with the process of wiring your 220V outlet, it is essential to take a check for the welding equipment in your inventory required for the process. If you don’t have them stocked up in your house, then you can hit the closest hardware shop and buy the following equipment:

  • A 6 AVG wire
  • Flush mount two gang box
  • two-pole circuit breaker. The amps of the breaker depends on the project so choose the right one for you here
  • Outlet cover
  • Cable ripper
  • Wire stripper
  • Non Corrosive adhesive

These are the essential equipment necessary for your project. If you don’t have any of them, then make a quick run down to the local electrical shop. Once you have all the equipment, you are good to start the process of wiring.

Phase 2: Switch Off The Circuit Breaker

The first thing to do here is to turn off the circuit breaker. It is important to ensure that no power supply runs through the circuit breaker box. Also, ensure that the handle is locked. The primary circuit should not be running during the process as if it isn’t dead, you might be running into the issue of burning your hand or getting electrocuted.

Thus, immediately turn off the main power before starting to work. It is also advised not to touch anything like metal parts in specific before you turn off the breaker. Here, similar reasoning follows as it increases the chances of an electric shock.

Phase 3: Remove The Metal Cover

The next step is to make sure the breaker is off to remove the metal cover of the breakers. We assume that you had a quick run to the electrical store to buy the equipment mentioned above if you already didn’t have them. 

Also, you should ensure that all the electrical equipment is of high-quality standards for this task to protect yourself and the equipment from any haphazard. In addition to this, wear the necessary safety gear like a helmet, gloves, and glasses before starting work.

For double-checking, just read the amps of the breaker to ensure that you are not using an overloaded circuit and exposing yourself to danger. At the same time, make sure you have the correct outlet and gauge wire that matches the plug of the welder. Apart from this, you will have to acquire an adapter for different plug sizes.

Phase 4: Identify The Make Of The Breaker Box

After you have gained access to the circuit breakers, you will require to assess the model and make of the breaker. Moreover, you should check for space to support a two-pole breaker in your box before you start working. The two-pole breaker takes up two spaces for functioning. If the box doesn’t support two spaces of the pole breaker, then have a quick run to the hardware shop for a change. 

Once you’re done with this and have completed all the steps so far, place the two-pole breaker in the box where two spaces are provided. At this time you are good to follow the next step.

Phase 4: Wiring

The next phase of this process is to start using wire to screw them to the breaker. Again, before you connect the hot wire to the screw, please ensure that the box has no running power supply and you’re following all the safety measures. We’re pressing on this point so much because you’re not a professional electrician, so it is important to stay on the safe side.

Next, you need to decide upon the distance between the circuit breaker and the place you wish to install the 220V outlet. Having figured that out, mark a point on that wall where you’ll be wiring the outlet. Attach the two-gang flush mount box and then screw it at that place. It is suggested to choose the closest route for the wiring. 

Also, before you start wiring, take note of the exact measurement of the distance between the outlet and the circuit breaker. You should ensure that there are 6 inches of minimum wire inside the two gang boxes. A cable ripper must be used for pulling off the plastic sheath from the wire. In addition, sheathing should continue to be exposed in the two receptacle boxes.

So, when done with ensuring sheathing and ripping off 6 inches of wire, now pull out with the help of the same cable ripper around 12 inches of the plastic sheath from the wire. This wire would be used inside the box of the circuit breaker. In the same way, as earlier, some amount of sheathing should remain exposed in the box.

Phase 5: Connecting The Wires

The fifth phase of wiring a 220V outlet is connecting the wires after the pulling out of the wiring process. So, now you would first work on the two gang boxes, which have wires inside them. You will require two types of wires – hot and ground wires.

Bare wires are ground wires, and red and black are hot wires, which you will need for connections. Ensure that you do not confuse them with the white wire, which is neutral and isn’t mandatory for the process. It is suggested to tape the white wire with electrical tape and place it neatly coiled inside the receptacle boxes. That is to ensure that you will not be confused by the wiring connection and make mistakes.   

Now it’s time to use the wire stripper that has been kept ideal at the table for most of the time. So, pick it up and strip off the sheath at the base of the wire of about 1 inch. Just be careful while stripping off the plastic sheath here, do not go beyond recommended. Then apply the non-corrosive adhesive at the base of the wire to protect the corroding of the connection.

Once you recognize the three wires, which are being used for connections, hook those wires against their corresponding screws. So, the red and black wires that are your hot wires should be screwed to the terminal 2-prong, and the bare wire screwed to the ground. If you missed taping the white wire, ensure not to connect it with the neutral wire.

As you are finished making these connections with the ground terminal and two-prong terminal, you can now safely put back the cover. Just ensure to place the cover properly back on the two-gang box. That is because this makes the work look more professional, and you can be proud of yourself for pulling this up nicely. But wait, there are a few steps still left.

Phase 6: Connecting With the Circuit Breakers

In the fifth phase, your work with the gang box is complete, but you still need to connect the wires to the circuit breaker. In this step, all three wires are to be safely connected back to the circuit breaker for the process to be completed.

For this purpose, you would now require to use the cable wire and wire stripper to rip off the plastic sheath from the tip of the wires. Next, in the same way, to prevent the connections from corroding, use non-corrosive tape to wrap the end. This will ensure that a stable and secure connection is established. Then, hook these wires up to their corresponding screws, as you did in the previous phase.

If you’re not having someone or a trained electrician for assistance, you can read the circuit breaker manual provided with the breaker. Thus, you will be helped accurately on how to connect the wires to their correct terminals. This way, you will establish a secure connection. Also, if there is another white wire, don’t mistake it for the ground wire. Instead of that, you can tape it beforehand.

By following this step, you have successfully established the connections and almost completed the entire process of wiring a 220V outlet.

Phase 7: Final Checks

After you have followed all the steps listed above with following along with all the safety measures, you’re just one step away from running your machine for welding purposes. The last phase of this process is double-checking the entire set-up and ensuring the connections seem to be established properly.

Also, don’t turn on the circuit breaker before checking all the connections to prevent sparkling on any loose end or exposing yourself to any dangerous event. While double-checking too, don’t take off the safety helmet or gloves anytime. Go through the two gang boxes and check the wires are perfectly screwed to the box, and that there is no chance of a short circuit. Follow the same process with the circuit breaker.

Once you’re completely sure that all the installations are secured or fixed, the loose ends and routed connections properly, you have almost finished the process. So, now cover the circuit breaker properly and ensure that it is placed properly. Again, you would want it to look more professional to earn a good pat, so make sure this is done properly.

Just after you are satisfied with the connections, plug in the welder at the 220V outlet. If you require an adapter for plugging, then make sure to tightly attach both ends for the smooth functioning of the machine.

Thus, now you can switch on the primary power supply that was switched off at the start. Along with the power supply, turn on your 50-amperage circuit breaker. Now, at this stage, the machine is quickly ready to be used for welding purposes, and you have done a great job here.

Are There Any Variations To The Method?

We have mentioned the exact step-by-step process for installing a 220V outlet for welding purposes for you. In our article, we have recommended the use of a 50 amp circuit breaker that will be perfect for use to draw enough current to your device.

However, if you prefer to use a higher amps circuit breaker for more degree of precision and professional purpose, it is completely fine. But make sure that it doesn’t go beyond the limit, and the circuit isn’t overloaded as that might cause an explosion or anyone can be electrocuted. Apart from this, there are no variations in the method, and you can easily set up the outlet on your own by following our guide.
