Question re: operation of pulse mode on PowerTig 200DX
I really like the pulse feature of this welder, but it's operation seems to be a bit confusing. Supposedly, if I am understanding the manual correctly, the amperage dial on the front of the welder determines the max pulse amperage, whereas the knob that reads Pulse amps should determine the low amperage of the pulse. What if the Main amperage is set at 5A and the Pulse is set to 50A? Does it just not pulse or does the pulse go inverted? I've never seemed to be able to get a low amperage pulse with the Main amperage knob set to 5A, and I was just curious if this was for the reason I just described about the functioning of the pulser circuit.
Also, the manual seems to indicate or at least made me think that the with the pulser engaged, the foot pedal only acts as an on/off switch to establish the arc with the dialed in settings on the panel controlling the characteristics of the arc, but I'm sure that when I step on the pedal with the pulser on, I get more current. Does anyone know what the real story is? I keep burning up .025 stainless thinking that I've got the amperage set quite low.
