    millermatic 130 xp will start an arc but not maintain it

    I got this millermatic 130 xp that will not maintain an arc. I can also hear the contactor every time I press the trigger on the gun. I have it set up with flux core.

    do you guys know of any typical problems with this machine.Name:  IMG_20200901_202345.jpg

    Not sure of the problem but you have the roll of wire mounted upside down.

    The wire should feed from the bottom so it goes straight into the feed tube.

    Try cleaning the inside of the drive housing where the Miggun plugs in.
    Needs to be bright clean Aluminum or it will weld bad and the wire may melt by the drive rolls. I use a rod a cut a slot in and slide in a strip of sand paper. then spin with a drill. after buffing clean with electrical cleaner.
