Welder runs fine but have no spark "current" to stinger. Have checked leads, cleaned with stone, exciter armatures, checked brushes (are in good condition). When grinder is plugged in, it runs at half speed. Tried moving rheostat back & forth, looked like they are making good contact. Does anyone have any other ideas to try or know what may be wrong with it?
Also, I live in the Rockford area. Would anyone know of someone who works on these welders or could test my welder for this problem??? The closest I have found so far is Stumps which is in the ST. Louis area - 6 hr drive one way.
Any help would be appreciated.
