I got a 400 amp Lincoln power supply and I am pretty sure my rotary phase
converter is to small to run it. It's an Idealarc R3S-325 and I down loaded
a copy of the manual and it say it will draw 51 amps. Any one try running
one of these on a rotary phase?

My rotary phase converter is an older factory built unit. It has 3 switch
positions. Center is off. Up is "Start" and once it's running you push the
switch to down. There is no markings that I have found on it. It's is a
large unit and runs my lathe just fine. My lathe is 7 1/2 HP. The question
is really will it run my welder. I plan on using .03 solid wire most of the
time, if not all the time. I will probably never run it turned up all the
way.
