    Default XMT-300 turns on but will not hold an arc to weld

    Help i need some advice. My new old 300 turns on all relays kick in and you can see plenty of amperage when you try to weld. The problem is that after the starter arc the machine seems to lose power. the arc wont carry and there is no welding when stick welding. I haven't tried tig yet mainly because i don't know how and got this welder to learn how. Any info will help thank you

    Thinking you have a failed Hall device, 156313. Or a bad connection on the circuit board. Might try removing and reinserting all the plugs on the PC1 main board.
