Hi All. This is my first real post (excluding my introduction post) so please go easy. My mig is about 20yrs old, and had a relatively easy life, but recently stopped. Its branded as a CigWeld Transmig 130 Twin - very much a home-handyman design as far as I can tell. Observations and actions so far:- Fan comes on Pulling torch trigger will cause wire to feed. Contactor does not pull in when torch trigger pulled. Physically activating contactor - seemed to burn wire that was between the welding terminals. Burnt resistor on control board (was still working) Burnt resistor replaced (3.3 ohm, 7.5W, replaced with 3.3 ohm 10w) - no effect. Reflowed all solder joints on the board to be sure. Will follow up with resources I've been able to find, and photos. Appreciate any suggestions.
