Serial Number is everything. Do a search of this group for maxstar and serial number. If you're unit is pre- LF 010173M, they'll exhange it free with a new Chinese made Maxstar if it's causing you problems. Ask for Mark Cadillac at Miller. It could be the cord, but that's really unlikely. I use 67 amps for 3/32" 6013-6011, 75 is right for 3/32" 7018. That's using 5 12ft computer power strips in a row, each with a 15amp breaker all on a 15amp brach. You can run all day at 67amps. 70+, and it will trip a 15amp if you run it constantly. Remember, the heating of a wire or a rod is given by the area of the circle you get when you it in half. Pi times radius squared gives:
1/16 gives 30 amps max for 6011-6013 3/32 divided by 2=0.046875 squared=.00220 times pi=.0069 or 69amps max 1/8 divided by 2=.0625 times pi/2 =98amps max 1/4"=.125^2 times pi gives 491 amps max These are real maximums, reduce 0-10% for 6011-13, increase 10% for 7018, 15% for 8018-9018, and 20% for 10018. Don't use 6010 with the Maxstar unless it's you ex's new husbands car you're fixing. 6011 is pretty. 7024 is like a stick version of mig. Not close really, but unique enough to be compared.FYI, just kidding about the Chinese part. It's worth it's weight in gold, IMO.
Ben,
Had me scared there for a minute. My apologies for not reposting sooner, thanks for your advice. Our local Linde rep got us another unit in today as a replacement, the original is on its way back to Miller for diagnosis, which I am eagerly awaiting.
Thanks again, Jim
I found Miller Maxstar 150 STL useful among all other welding machine. I hope you will try it at once and share you experience. You can check it her:
