  • Miller bobcat 225

    I have a Miller bobcat 225 when I put it on 3/32 setting and it will not strike an arc. But it welds good on 1/8 and 5/32 setting. What would cause it. Any suggestions would be appreciated thanks

    An open circuit in part of your setting rheostat?

      How do I fix it and do you know where it is located at. I took the front off and cleaned the contact points

        The contact points on the setting rheostat?
