hello all,
thanks in advance for any help you might be able to provide. I'm a newbie and found this forum.

I have a Syncrowave 180SD older model, but very little usage and worked fine for all my small welding a few years ago. It's been stored in our normal garage.

setup: max 60 amps, "tig", negative electrode. argon set to 18lb flow, tungsten is 1/16" 2% thoriaded "red" Ground is clamped to the top of the welding table which is a steel/stainless steel type cart that I've welded on before (all of my welding)

I'm welding a typical 2" 304 stainless exhaust pipe to a header type flange.

I tap the peddle away from the machine for the post flow. Bring the tip to my work piece and almost instantly when I touch the peddle to start the weld, it will burn a hole immediately through the work. With so few settinges on the machine, I can't imagine anything, but that there's an issue with the machine.

Anyone have anything else i can check? or insight into what might be wrong?
