Default Re: MIG welder fault

Check for supply from transformer. Some migs have separate transformers for control electronics and arc supply. Check continuity on wiring to trigger. If possible try pressing main contactor in manually whilst attempting to get it to arc up on a piece. Lastly check general wiring condition and check rectifier diodes as these can burn out. Cebora migs are generally pretty robust and if you scout about on net you should be able to find a wiring/service manual.

Hope this is of help
