We got an old square wave 355 that has been starting to eat up the electrodes for the high frequency starts. We have the gauges, it's at the suggested spacing. I still got some ideas dealing with resistance to track down but would appreciate feed back and any ideas in case I'm wrong.

First thing I'd try is polishing the electrodes. I'll remove them, chuck them one at a time in a good drill press (a mill is better) and run them against a fine flat grinding stone. This knocks off all the tiny arc marks and lets you start with fresh metal. Then reinstall, rinse with electrical contact cleaner, and reset your gaps.

90+% of the time, this resolves HF issues.
