Reply:thanks for the replies. i guess it's a good thing i got rid if the dryer and make the wife hang clothes out to dry {lol}, just kidding. added a wash room off the back cause she didn't like standing in the garage to do laundry. more room for me to turn an burn.
Reply:While the manual recommends a 40A breaker, Lincoln's manuals are notoriously confusing as to why.  These machines run very well from 30A breakers, but it is incorrect to state that they draw only 21A.  That is at its "rated output" of only 130A.  It will draw significantly more at their maximum output of 175, just at a lower duty cycle.  This is why you must make sure it is a 30A time-delay breaker, which most are.

Reply:As mentioned, the Lincoln manuals are misleading.  Naturally, it will operate just fine from a 40A breaker and #8 wire.  It's your money.
Reply:Probably around 27± amps at maximum of 175 to 180 amps, with a 10% to 15% duty cycle. So you've got a minute or a minute and a half at just under thirty amps before the machine either craps out or starts to act erratically on a 30 amp breaker. Of course a lot of that has to do with the type of wire and whether you've got it really buried in there good on nice hot run or not. Most of the time it would be a rare occassion or an accident if you reached the 175 amp output with out some prior planning to do so. I've stuck my tip and/or diffusor right to the work piece and managed to let off the trigger before tripping a 30 amp breaker.
