I bought a usedGunslinger and it's not behaving the way I expected. I'm a rank amateur but the 250X we used in class was a lot easier to use.
I'm using 75/25 mix, .035 solid wire, and input power, gas flow, ground, etc. are all good. It just doesn't short circuit weld smoothly, no matter what settings I use. It spatters, arcs, drips, you name it.
When I measure the voltage at the gun (trigger pulled, not welding) I see 39.9 volts at all settings. While welding (it's really pretty tough to read a volt meter while welding at arms length with no helmet) the voltage jumps all over the place.
The local Airgas guy (who's never seen a Gunslinger) says the open torch voltage should track the meter. Is this true in general or is it a Miller thing?
