    I like to recess the contact tip about 1/8 inch.

    I carry a file(for years) just a few quick strokes with the file works every time

  • dimmyrocks:

    yeaah the tips are ”cheap” just unscrew it cut the wire and throw it away! NOT!!!! they cost 2 bucks each, if its got wire stuck in it just grind the end of the tip off, just like @ americanfabricator said

  • SPACECADET2U:

    JMHO….if you are birdnesting, the feed rollers are too tight…..

  • TheLightningStalker:

    Usually once the tip cools a little bit, the wire will break free and start feeding again. Just flick the trigger a couple times and it should break. Don’t hold it down or you could end up with a birds nest. Check out more MIG troubleshooting vids in my channel.

    haha i heard that… sometimes all it takes is to just grab the nub of the wire and pull. only once have i really HAD to change tips because of this.

  • AmericanFabricator:

    BS – just grind tip and the tip is brand new. Miller wants more money.
