cool thanks for the advice... thats the way i look at whats the point in buying a MM140 and then 2 years down the road when its way undersized then i will end up buying the 252 anyways so why not just save up and buy one machine. but i was just concerned that maybe you coudnt turn down the 252 enough to weld thin things like sheet metal.

Sundown do you have a link to the gun your talking about, im still learning so i dont completly understand you, i thought you only used spoolguns for aluminum
