First off, great forum ! i've been reading some interesting posts and carried out some tests from the info I have read, but would like further help on my welder that has just stopped working?
Problem: "Not welding / producing an arc"
The wire feed works when I press the trigger, the internal fan operates and the switch light illuminates.
I've checked continuity on the earth clamp back to the wire connection inside and it seems fine.
I've removed the rectifier that has a 4 diode set up (2 pair) and put a meter across each diode to check them, they all worked in one direction only reading at about 280 for each one so I think I can rule them being the fault.
I have checked inside the trigger and despite being a little dirty seems okay.
Can someone tell me what I should be getting when testing the large transformer that sits at the bottom right and also should I place my meter across the two cables that connect to the rectifier? I've attached some photos to help
Also what else should I check as a process of elimination?
Many thanks people.
