LIGHTNING MTS 275 with TIG Package Amp and Wire Size

[Bkewlbro]

Hey! So picked up the "LIGHTNING MTS 275 WITH TIG PACKAGE" I'd say a year ago... lol I just not got to pulling it out and installing a plug-in for it. I have her a a 50amp 240v breaker, but I was wondering if I needed to upgrade the wire gauged to be safe. Anyone that has one of these units, what size wire did you run from your breaker to the plug?

I've always followed that, if you're going to run a wire between a 50A Breaker and a 50A Receptacle,,, it should probably be a Wire Rated for 50A

I have the same machine. I have a 50A breaker and AWG 8 wiring to the plug. I also made a 40' extension cord using AWG 8 wire and it all has worked fine for 10 years and 3 different welder and a plasma cutter.
