  • Miller Vintage Performance Drop Off

    Hey guys,

    I have a question. First understand what I do not know about welders and welding would fill volumes and volumes.

    I have a Miller VINTAGE welder running 220 from a house line. There is maybe a 50' extension cord from the meter to the machine.

    I start to weld and I can get some good bacon sounds going but maybe 3-5 minutes into welding it seems like the voltage drops or something goes awry. It just seems like it's strength drops off.

    Is there a name for this and is there a part inside I can change to try to fix it?

    TIA!

      100% likely its the gun, try replacing the liner first.

        I recently had a loose screw on one of the terminals on one of my cords.

              Does the cord or plug get warm?

                Liner can be ruined the day it is installed. Pull it and check it out.

                  Liner, tip, or plugged wire guide to the drive rolls, especially if you using a absolutely useless lubricated wire felt cleaner.
