Well, I figured that, I'm thinking that it is 8 or 6 gauge because it is thicker than the 10 gauge extension cords. I just don't want to have to turn the power off and take things apart unless I have to. So with that said, the wiring is at least adequate for 30 amps. I guess that means that I now only need to make an extension cord or move the welder when I need to. With that said, could I make a sort of extension cord out of the wiring that is in house walls(has the white plastic looking insulation on it) that is 6 or 8 gauge to plug into the outlet and run it to the shed when I need to? That way, I know the cord is heavy enough and I don't have to worry about electrical fires. The cord won't stay outside so I don't think weather would be a factor.
