Making an extension cord by yourself might help you in an emergency situation, but the cord might not meet all industrial standards and work for a long time.

Best Welder 220V Extension Cords Buying Guide
If you want to know how to choose the best welder extension cords, I have some tips and advice.
First of all, the cord would be compatible with customer and industry standards and have a set of specific technical features.
Things to Look For when Buying an Extension Cord
You extension cord you get should be at least a 6-gauge copper cable, which includes copper conductors.
Therefore, copper conductors will ensure consistent energy deliverance.
Next, your cable should have a NEMA 6-50 plug and receptacle.
There are plenty of cables with quality insulation that makes the cable abrasion and chemical resistant.
Additionally, the cable needs to be UL-listed.
The Length
For a home user, you can get away with a 25-feet long extension cord.
However, if you are a professional, you have to get a longer cable that you can use in a variety of work settings.
Pay Attention to Heavy-Duty Tag
Having the heavy-duty tag with the welder extension cord doesn’t necessarily mean that the cord will be able to accommodate your welding machine.
You should compare the amperage ratings of the cable and your welder.
Commonly, you can find many “heavy-duty” extension cords on the market, but they are rated only at 15 amps.
Therefore, getting an extension cord with a rating of 50 amps at 220/240V is always a safe choice.
Why Avoid Standard Extension Cords?
When using a less-powerful extension cord to supply your welding machine, you can get in a dangerous situation.
Voltage drops can happen, and make your welder overheat, or worse, catch on fire.
Therefore, knowing the amperage of the extension cord and welder is highly important to prevent dangerous situations.
Safety Precautions
Tipping injury is the most common injury when there are extension cords on site.
Therefore, you need to secure your extension cord to the ground in any way.
Placing a rug over it might be helpful, but the rugs are prone to fire.
You can get small plastic fire-resistant risers that can be an excellent solution for grounding the extension cord and preventing fire and injuries.
Avoid covering your extension cord because when covered, the extension cord can easily overheat.
Besides, you should never run your extension cord through ceiling walls, floors, or doorways.
Most importantly, don’t try to modify the cord in any way.
Avoid cutting the cord, because it can cause irreparable damage to the cord and make the cord hazard.
Electrical Network Considerations
Before you start welding, you need to check if your electrical network supports your welding.
Standard outlets are usually rated for 15 amps.
However, if you are using an extension cord of 110 V you need a 20-amp rated outlet
Still, the majority of households have one 220V outlet, suitable for welding machines.
Check around dryer machines or HVAC systems.
Price Range for Welder Extension Cords
The length and quality of the extension cord determine the price.
If you are looking for a 25-foot extension cord, you can expect to pay from $30 to $50.
Next, a 50-foot extension cord might cost you from $45 to $75.
Those who need an extra-long extension cord, with 75 feet in size, can pay more than $100.
Conclusion
The best welder extension cord is Southwire Heavy-Duty STW 40-Amp Welder Extension Cord.
It is reliable and has excellent safety features.
It might be shorter than some other models from the list, but other features overcompensate for the length.
The cord can withstand years of heavy-duty use and the cord has great weather-resistant features.
