IMig 140 Power Supply

Hello All,
I purchased a iMig 140 to use for simple jobs around the house. I decided to have a dedicated circuit for the welder. The breaker in the box is a 30 amp. When I plug the welder to a regular 15 amp circuit and set it up for an 1/8 plate using 0.30 wire and a 25/75 mix I can get it dialed in, but the weld is a little cold. If i keep the same settings and plug it into the dedicated 30 amp circuit it burns to hot and almost burns through. The question I have is shouldn't the welder draw only what is necessary for the settings? My gut feeling is maybe the dedicated circuit being only 6 feet from the breaker box has a increased voltage. Any advise would be appreciated.

Thanks,

Chuck, the unit will only pull what it needs from the panel settings. So how close to the breakers will not cause a problem. If you vary the volts, do you see a change in the power?

Mike,
I do see a change in power when I vary the volts. Plugged into a 15 amp circuit the tuning was sluggish, but plugged into the 30 amp circuit it is quite sensitive to slight changes and feels like it has a 1/3 more power. I like having the ability to apply more heat when needed, but wouldn't think that just plugging the unit into a different circuit would make that much of a change.
