For all those that my be thinking that is the end all be all to their welding problems. Keep one thing in mind. It WILL NOT output AC tig, meaning thin(er) aluminum is going to be out of the question.
By the time you get that thing tooled up to do steel, stainless and aluminum, you will be on the north side of $1500.
Odds are the duty cycle won't be that great which won't much matter for a mechanic or race car guy -body man, but I need 100 percent when a fab job comes in.
The MP will probably be around 20% at 210 and 50 at 130 or so.All day long on 1/8".
I have tops and bottoms to weld on thirty three 4 x 4 .250 wall columns here in a little while.The guys are drilling and bending tops and bottoms.The tube is cut and racked.
That's 90 feet or so of bead. My 180 Lincoln can't play that game non stop at full blast. My old MM200 will yawn at it(280 amp rated machine).
My advice on aluminum is let someone else do the fine work. Someone who does it day in and day out. I used to. I don't now. I spit out a bead with the spool gun and stick stuff together these years.
Aluminum welding is completely different than steel or stainless. One minute the puddle is there and the nezt everything goes to hell..
That said: I too amp buying the MP210. If it runs great I'll sell my Esab 200 stick. That will in itself pay for that Lincoln.
