    Question mm200 tall narrow beads

    i have an old mm200 that does not seem to work that good ,no matter what i try the weld bead wont lay flat its real high ? i have had other welders and you could adjust the slope to correct this ,i have other welders that work just fine so i know its not me .anyone know what it could be?i was thinking maybe the capacitors?

    Cool

    What size of wire do you use and what gas? The MM200 should lay a perfect bead. My dad had 3 of them...Bob
