    Default ticking noise

    My dynasty 200dx making weird tick/click noise when I press the pedal. I remove the case to see its the arc jumping the points. The machine was fine the last time I used it.

    Quite normal as the machine is charging and discharging all the time, to either maintain the arc, or when not welding maintaining an internal charge, and of course the hf makes a noise, depending on the year.

    Open er up, and check the voltage pickups, just behind the output studs, likely the brass nuts that hold the pickup plate is loose. tighten them and red loctite the nuts in

    Innershield uses no gas, Dual shield uses gas (CO2)

    Innershield is (generally) straght polarity so pos is to the work clamp, and pickup off the VS feeder and neg to the feeder's lug

    Dual shield is reverse polarity, so pos to the lug and neg to the work clamp and pickup
