Hi All
I'm new here after inheriting a Migatronic 5000MX that has some sort of fault. I'm loathed to request advice as my first post but after a week of head-scratching, I'm running out of options!
The welder would be perfect for me for some light garage and farmyard repair and generally appears to be in good clean condition and definitely has not had a hard life so hopefully, I will be able to extract a few more years out of it.
However, when the welder is plugged in it clicks, hums and the fuze light stays on. But when the trigger is pulled nothing happens - no wire feed, gas solenoid etc.
Migatronic kindly provided the attached schematics (the PCB is the same as a slightly later 180) and were pleased but surprised that a machine from the mid- 80s is still in circulation.
I've been through and tested the PCB components and switches everything appears to be in order there.
The one thing I can't get my head around is the feed to the torch trigger (a non-euro torch conversion). Both wires leading into the trigger is supplied by 24V. One directly fed by pin 1 on the PCB and the other via welding power. So when the trigger is depressed there is no change in the voltage on either side. I'm assuming this can't be right, maybe something is wired incorrectly. Although everything appears to be consistent with the Migatronic schematic.
Any views on this would be much appreciated!!
