I recently bought an I-TIG 200. I have a question about an extension cord. I have read the threads on several sites( pirate, OFN, weldingweb,etc) about buying a 10/3 cord and replacing the ends with the proper ends for 220v. Looking at the specs of the welder I bought, it says 30A max inrush current. a 10awg wire is good for 30A... I asked an electrician friend, told him what the max current was and the max operating current. He says i should go with at least 8awg, or ideally 6awg! i think that was a bit overkill.

I have 40' of 10/3 SO wire. This cord will only be used on my Tig. Also, this will be going on a 30A breaker. Will 10/3 be heavy enough for me?
