No hi frequency start on 180sd

[2gofaster]

I bought a Syncrowave 180SD a few months ago. Up until last week, I'd only been welding .063 304 tubing. Went to weld some aluminum for the first time and the hi frequency arc starter never seems to engage. Even thinking it might be something I was doing, I had my friend who owns a dynasty 300 try it. Nada! Welds fine in DC, but throw it in AC and no arc. It will just barely spark and that's it. Any help would be appreciated. Just thought I'd check here before I called in.

Call it in bud. Sounds like the HF is not working properly. The service dept number is 920-735-4505. Press "3" and ask the operator for TIG products. They will tell you who is close to you for service.
Sorry to hear of the trouble.
