Hi i just bought a 1995 syncrowave 250 serial number starts with ke. but i have some problems well one big problem. i have no arc with the torch or if i just try to arc weld. the welder turns on but the hf is defenitly not working i checked the spark gaps and i cleaned them up but it didnt seem to make a diffrence. i was woundering if any body has some ideas or a way that i can troubleshoot it?
