Default "Tip Saver"

I work with a mm 350P and it has run great for years but recently it won't weld at all, it acts as though there is no ground. The wire feeds but when it makes contact with the base metal it give a slight spark and then stops giving me a "tip saver" help code. The code says that the contact tip is touching the base metal. However the contact tip isn't touching the base metal. the tip is recessed about 1/4" inside the nozzle. I've checked the plug, I've changed the ground, I've changed the liner, I've changed the gas diffuser, I've changed the contact tip and the nozzle to no avail. I'm working with .045 wire and running in pulse mode welding carbon steel. Any ideas on how to troubleshoot this?

Give Miller a call 920-734-9821.

Their Tech Support people have been very helpful the couple of times I have talked to them.
There is nothing quite as permanent as a good temporary repair.
People are not the solution, because Most People are the problem...
