  • Dynasty 300dx stopped functioning

    Dynasty300dx built in 1999, excellent machine i have used it everyday for 5-6 years.
    Problem, in either AC or DC tig mode, when i press the foot peddle, its changes the either tig process to stick function when the peddle is depressed. I let off it changes back to tig mode. All the displays work and menus.

    Dynasty 300 DX Tig, very nice machine, AC doesn't start most of the time
