Smile ArcWelderCircuit

First of all would like to say thanks to anyone who can answer my question.

Question is I have an arc welder that is 115 volt and says it operates at 26.6 amps.

I was told before and pretty sure even the box of 12-2g wire says that u should only use a 20 amp breaker on 12-2g
If i were to run a circuit for it what should i make it, 30 amp breaker and 10-2g ? I shouldnt even try it on a 20 amp breaker 12-2g circuit should i.

Thanks.

A lot depends on the duty cycle of the welder. So unless, it's a 100% I think a 20 amp circuit will be fine.

Does it have a 20 or 30 amp plug?

Says duty cycle 100 % up to 50 amps
Tapers to 20 % at 100 amps
The plug on the end looks to be replaced(its says 15 120 on bottom). So i definatly need to replace the plug to a 20 amp one.The wire on the plug doesn't look like very heavy ( if i had to guess id say 12gauge plug wire) and i was think of replacing it too. i might take it apart and see if it looks like its original or replaced and change it to heavier.

Then I would say 30 amp circuit.

You'll need to get an RV plug/receptacle or an L5-30P & R if you want twist-lock.

I wouldn't change the cord, depending on the insulation, not the wire size, it may be already good for 30 amps.
