I just got a millermatic 175 welder. 230v, 19.5 amps. I'm going to make an extension cord for it and was wondering what guage wire I should use. Is 12ga enough? (going about 30 feet, just enough to get all the way around the garage, and into the driveway a bit)
Also, the dryer outlet is neutral grounded. Should I use it as is or add a second outlet with a real ground? |

I think you want the 8 gauge wire for that, I used 4 cunductor orange sheilded 8 guage from Home depot, it's like 88 cents per foot. I have about a 30 foot extension cord, and my setup is the same as yours. I think for a buck a foot you can move up to the flexible wire - I used leftover from wiring the other garage to make my cord.
As for grounding, the welder is neutral grounded as well, so there's not much to be done unless you yank out the OE plug all together and replace it, or have enough ground wire on a wing nut to the chassis of the welder chassis itself (so it can be removed when you are not using the extension cord) |
