pure dc

admin

Hey guys I have been looking at sae welders and cant help but wonder sa200,250.300are pure dc using a dc exciter but the 400 uses a a.c. exciter does the 400 only use vthe a.c. for the 120 outlet or is this basicil a big alternator like the millers? I realize the older ones had aluminum but other than that do they weld as good as sa200 ? Any info is appreciated.

Reply:thats what they say but is there a reason?
Reply:B1det - FWIW, the 250 has an AC auxiliary. The AC output is rectified to DC for the main generator's exciter current.Hope it gets you closer.Good Luck
Reply:So does this mean the arc is actually as rectified to dc?

Reply:SA or SAE they both weld mighty fine.Disclaimer; "I am just an a$$hole welder, don't take it personally ."
Reply:Checking the Lincoln website manuals, they appear to have come in engine, AC motor and DC motor drive configurations...........
