I bought this syncrowave used: my mistake. Worked pretty good at first and then started acting up. I had it worked on at a Miller dealer and it worked for a while. Multiple symptoms but one of the strangest is when set up to TIg on DC, the machine will switch over to stick on its own! I think it is about a 1998 vintage machine with push buttons for selecting prcesses, etc. When it was still usable, it would often take a few second "time out" after attempting to start a weld. I also have started getting the help code "2" and have to kick the pedal on the off side.
Any help would be appreciated. Thanks,
