Well, I'm picking up my mm251 with spoolgun on Tuesday, dual cart, two regulators.
So I need to put two nice big tanks of gas on her, and grab some 4043 wire.
I'm thinking around a 140cf-ish tank of Argon, for aluminum (and eventually for a tig machine I understand it goes fast on tig.) Unless its even cheaper to fill a larger tank. I won't need a ton of gas up front, but down the road I'll regret going small, as I already have.
As long as it still sits on the back of the welder without tipp'n her over, lol.
I know for a fact, I'm going to want to see what this thing will do on spray arc, for anything from 3/16's to 1/2"
Just because
I'm thinking maybe 98 AR / 2 O2 will be the ideal gas for spray arc on the MM251? or will the extra amperage capability allow for a cooler, possibly more versatile gas?
Or would 92 AR / 8 CO2 (C8)
Or (C5), or (C10) be better?
Or is the O2 the way to go for ideal results? (which I know is true of the MM210)
I may still weld 1/8th to make a welding table, and carts, and the like, which I assume you still need to short circuit, and I assume you want to go back to C10 or c25 for that. (or pull out the old 120 volt machine, heh)
If I could get away with something that does both spray, and other processes, then that's what I'll purchase on Tuesday.
I'll be dropping quite a chunck of change on the O/A tanks as well, so trying to make the most efficient decision. Not to mention make up my mind, before the dealer tries to just push off whatever they have in stock as being better.
Thanks in advance!!!
