Hi, Have powermig mp350 and a sg100 spoolgun. I noticed that the powermig 255 will work with the sg100 but the mp350 is not listed. Is it possible with a 6 pin to 7 pin adapter to make this combo work? Really prefer not to fry either either unit if you know what I mean! The sg100 would be nice for really thin materials, and my push/pull for heavier. thanks ed
