  • Millermatic DVI mig welder, no spark, bad ground?

    so i did a couple of google searches and i see where people say to clean the spark power selector. i took mine out and wire brushed all of the metal contacts and still no dice. the first time it died we were able to move the selector back and fourth a few times, it came back on, but died again.

    when i put the gun to the ground clamp, i get a very faint spark but it does not ignite. everything else seems to be working. i opened up the case blew it out with some air. everything seems to look good inside.

    any real suggestions? i cleaned the contact switch twice and nothing has changed.
