Hey everybody, I had a dryer outlet that was not being used (we have a gas dryer now) and I needed a power outlet for my new millermatic 175. I tested the line with my multimeter and found it was putting out 236 volts. I replaced the dryer receptacle with a 6-50R and buttoned everything up (the breaker is actually a 30a in the box). The welder calls for 230v 19.5a, 60 hz so I'm thinking I'm good to go. The dryer line is a 1 phase so the bare wire (ground) is in the correct spot, but does it matter which post I attach the black or red wires (reverse polarity? i'm pretty sure there's no such thing in this case). I checked the voltage after I installed it and I still came up with 236v (even when i switch my tester leads to either side)so I'm assuming evrything is okay. Can someone verify this, I dont want to screw up a new mig welder or burn the joint down. thanks in advance. walt
