Have this machine. Serial # RH706086. It is a 3 phase welder. ÂÂ*Have it wired, but has very little output. Voltage control nob has no effect. This machine maybe wired for 460v need to jump it for 230v. Can anyone help???ÂÂ*

Assuming it was made by Miller, call their tech support guys and get a manual that will show you how to jumper the input wiring. That has to be the first step. 1-800-4A-MILLER

is the fan running?

Everything runs in the right direction, ÂÂ*going to call tech when I get a few minutesÂÂ*

If the fan runs at full speed it's wired correctly

What full Airco name is it? Normally they say Aircomatic CV-350 or something similar. I have a bunch of old Airco manuals. I don't think Miller keeps them any longer.
