admin

Reply:Um, not knowing what welder you have, I'll say yes it should power the 150.Maxstar 150 - Input Power: 115/230 Volts, 1-Phase, 50/60 HzWhat process are you using tig or stick?Edit: what type of joint are you doing?Semper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!
Reply:I  doubt he is tigging a 1/2" plate with a 150amp max tig.I'd assume he's using stick.
Reply:According to Miller, the Maxstar 150 requires 4900 watts at full output power on 230V input, and generators tend to be rated "optimistically", so even if that gen has a 230V outlet, it's marginal.If the generator does have a 230V outlet, it will probably work if you stick with 1/8" rods and do multiple passes.If it only has 120V, you're gonna be stuck with 3/32" 7018 or 1/8" 6011 at best, so it'll be slow going.JohnA few weldersA lot of hammersA whole lot of C-clamps
Reply:I never assume, it only makes a A$$ outta U and ME...lol, j/kI practice on 1/2" tube wall all the time, actually is 5/8 wall, but they turn the inside down to clean scale.I actually used this machine before. The plant just bought 3 of them for quick emergency repairs.I had to weld 1/4" plate in a hurry so I figured I would open the box and grab a cord and run up there.Maxed out on 120v, it's all that it wanted using 3/32" 70183/32" 7018 Suggested Amperage Range: 65-100, I normally run 3/32" around 95 amps in the shopI figured since it was rated for 115v 100 amps it should't have been a problem.It was all this thing wanted to do, I even had to long arc it a bit to get the heat up.My opinion after that was...miller over rated the amps.Never tried it on 230v setting, but if Miller states it's capable of running 150 amps then it should be good for 1" steel w/ multi pass...no? Or are they over rating their amps again.....Idunno.Burn rod with it and see what it does.Last edited by skelley521; 09-11-2011 at 09:09 PM.Semper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!

Reply:I think the key words in Skelly's thread were "grab a cord". What gauge and how long?                                               MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw

Reply:Yeah, it could've been do to the cord. It was a couple of years ago so I don't remember.Semper FiJesus may have been a Carpenter, but his dad was a Millwright" A grinder and a can of paint, will make a welder what he aint' "I've done so much, with so little, for so long, that now I can do anything with nothing!
