I have a Miller 35s with a Bernard gun. How do I know what model it is. The reason is that the gas nozzle and diffuser I think need to be replaced. The contact tip just started pushing out when I go to weld and it seems that it burns back and welds the tip. I went to clean the nozzle with a plumbing pipe cleaner and cleaned the wrong end. The nozzle seems to have some sort of resin as the insulator and I think it is shorting out. Help !!! Tom
