Hi all
I have just picked up the Miget from Pauly at the weekend, sold as seen, to try and get it going properly. You may have read about the issue here:
https://www.mig-welding.co.uk/forum/threads/murex-miget-blowing-32a-breaker.88715/
Bit of an update, originally we thought the issue was just tripping the circuit breaker on power 5 or 6 but I tried it out on Saturday and it will weld on power setting 4 but it's definitely not right. Basically it is totally down on power, so welding on power 4 it is laying a 2-3mm wide bead which looks smaller and cooler than I would expect on power setting 1.
Pauly spoke to a repair centre, and they said it sounded like the rectifier is shorting.
I expect the answer is no, from what they said to Pauly, but is a rectifier testable as a component or would it only show up under load? I have to be honest, I don't know much about the theory of how a rectifier works, but I am happy wiring things up if I can get a map of what to wire to what. Just want to know if there is anything to test before I buy a new rectifier?
A couple of the small discs between the main plates look like they are touching at the edge. Could it be as simple as that?
Thanks
Matt
