I have a millermatic 210 and I have a spool gun for it. The drive rolls on both the spool gun and the regular mig gun have stopped and do not feed the wire on either gun. I have checked the CB1 circuit breaker (drive roll breaker according to the manual)and it is fine. I still have power to the wire because it arcs when I touch the work peice and the gas solinoid still opens and sends gas to the guns. Any ideas of the next place I should start checking. Thanks. I have never been without a welder before, I feel kind of naked and lost.LOL
