Hello by the way.

Innershield or dual shield, big difference, what kind of machine are you using?

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.

An airco wasp 180 near equivalent to a Miller roughneck
I just got the 12vs I did my best to study up beforehand but guess not enough

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.

I having erratic arcs and the display panel blinks when on the pedal. I know these dynasty have a humming/whine sound.

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

Can you explain the difference between inter shield and dual shield and why it makes a difference

[cruizer]

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
