Miller aerowave not working, amps set to HIGH value and cannot change
My coworker has a Miller Aerowave TIG welder. It did work
previously. Now it does not work. The amps display shows a very HIGH number that cannot be adjusted with amperage knob. It does weld at that extremely high setting and melts welding rods. I have some pictures of the welder and board LEDs at: https://www.machinerymoverschicago.c...elder-Problem/ Would anyone suggest a solution? Also does anyone know a good welder repair shop on the Chicago area? Thanks |

If one end has gone open it could be pulled high or low causing the welder to think you want full current. If you're confident of not electrocuting yourself, try to measure the voltage on the wiper of the potentiometer as you wind it up and down and see if it sweeps up and down. I'm not familiar with high end welders and can't believe how much electronics there are inside that one! |

Have you downloaded the owners manual: https://www.millerwelds.com/files/ow.../O319H_MIL.pdf Looks like a nightmare inside without the full tech manual to guide you around. Much more complicated than the Millermatic I'm trying to repair... I see you found the Miller Forum. Nobody has jumped forward to help you so far but it hasn't been up long. You might get a tech manual from that site if you ask nicely :) -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |
