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? |

All hail the god of archives (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif) I searched before asking and found some good threads on this subject, including this one. But I still have a few questions. 1. What's the upper limit on how long a 220V extension cord can be before it becomes a problem? 2. If the welder is rated at 20 amps why did they put a 50 amp plug on it? Don't they know that most of their customers are guys trying to repair rusty cars in their garages? |
