Hoping someone can help!
I recently picked up a Comparc TIG-250... It looks identical to a Older Syncrowave 250, has a shunt, and seems to have the same wiring numbers as the older syncros do.
Problem with it is.. It has no amperage control, nor do the voltage and amperage gauges work... It burns a rod like its set at 300 amps.. In another words.. violently!
So far I have:
Replaced the EMI filter
tried using it with the EMI filter unhooked
Tried using a remote and the panel control knobs
checked the panels rheostat - which checked out good.
Visually inspected the circuitboard - no visible burns
Visually inspected the wires... all look ok..
Other then a new circuitboard.. what else can I check?
Is there still a LEM conversion kit available for the older millers?
