  • Miller 180 Trig Start Welding and stop after few second Please Help

    Good evening,

    I’m new in that forum and sincerely hope someone had the same issue as mine and can help me out.

    Today, I start having issue with my Millermatic 180 doing special behavior
    during welding.

    I tried to find some information via internet from different forum and I found that Miller Forum with quite interesting information. Unfortunately, I couldn’t fend anything regarding my problem.

    Here are few points describing what the problem is:

    I was welding my truck tow hitch; I release the trigger in order to knock the weld area with hammer. After trigging to do a second pass on my work piece, the welder stop after 2-3 seconds.

    I release the trigger, trig it again, it restart but for another 2-3 seconds and unfortunately it stop again.

    After several times, I tried to trig only for feeding the wire, it start few second again and stop.

    One thing that I notice by hazard is the following: When I adjust the voltage to any number, let say 4

    1 I adjust the speed to 1, I trig and the wire come out from the nozzle with exactly 1 inch and stop.

    2 adjust the speed to 4, I trig and the wire come out from the nozzle with exactly 4 inches and stop again. I trig again without changing the speed and exactly 4 inches again come out and stop.
    3 I adjust the speed to 7, I trig and the wire come out from the nozzle with 7 inch and stop.

    When I trig, the wire always come out and the speed increase and decrease as adjusted and it arc every time, if I touch my metal piece. But as above, each time it stopped after few second.

    Is there anyone who can help, I thought in first place that maybe I trig some testing setting, calibration settings, or something else by mistake without noticing it and it start.

    I will really appreciate if someone had that issue and how they fix it out.

    That machine is like new one and hopes it is not a huge issue.

    Thank You for your help and congratulation for that forum

    Best regards and Have a Great late evening to all.
