Didn't get it done today. Thanks for trying to help. I'll follow up when I get it going next week.

I had the manual. I checked trouble shooting section already. There is no air to this unit. It uses a Tweezer handpiece, pressure is applied by hand.

Thanks, I have looked at any obvious problems; grounding, leads, possible damage to the handpiece.

I'm spot welding stainless sheets with Entron EN1000 and TW110 handpiece. Have done alot of it. Now my handpiece is getting hot as well as the leads and its burning through the metal. All my settings are the same, it just started happening. I am not an experienced welder, if it weren't New Years eve...
