I have searched and searched.

I did check the contacts cleaned and set at .010

I did blow the machine back out and clean out the dirt dauber nest in the bottom. It will weld on lift and stick.

Where do I check the input voltage to the HF transformer? it looks like the transformer is behind the HF contacts. The machine is an 2005 model, this is the first time I have had any HF problems, actually this has been the first problem I have ever had out of the machine.

Where do yall check to see if the pedal is triggering for the HF I had seen that some people had some HF issues over the pedal. My pedal did try to commit suicide off the cart a few weeks back but was saved at the last second by the cord.

Trying to weld up some band saw blades with no HF is proving to be next to impossible.
