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 saw a hole in the wall of a concrete block building from a similar incident. No one got hurt real bad, but one of the guys got some pretty good burns. The guys told me the thing took off like a rocket, literally. Also turn off your regulator too. It's better for the diaphram in the regulator, and less of a hazard. If you leave the regulator "on" and open the valve the compressed gas cylinder, there's a sudden rush of gas that heats up the valve in the regulator. This is especially critical on oxygen cylinders. If by chance there's ANYTHING combustible inside that valve (like a spider web) it's BOOOM! I've seen pictures of the results. |
