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

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

  • Hello, Would it be any problem if I just unblock and clean the contact tip when burnback happens? Thanks..

  • @dimmyrocks I don't know where you're buying your tips, but you'er getting ripped of if you're paying $2 a piece.

  • what the fuck, you never get rid of your tips, you get plyers and take out the wire, or it should free itself when it cools, what the fuck you cant weld steel to a copper (thus the tip is copper). fuck you miller, thats why i dont get a miller coz of bullshit that wants them to make more money. fuck miller i bought a cigweld transmig 200

  • You can also get birdnesting if you use crappy mig wire. I bought some HF wire and it was kind of dirty. It just did not feed well and it would bind up no matter how I adjusted the roller pressure. Had no trouble at all with Hobart wire. Sometimes I have problems with Lincoln wire.

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

  • Great tips, thanks

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