I've owned my PP256 for nearly three years now and just getting around to trying my hand at TIG. While setting up the equipment, (took the regulator from the box for the first time) I discovered the Argon regulator (supplied) leaks like crazy. After disassembly from the tank and inspecting the fittings did I discover cracks in the body radiating from the apparently over tightened fittings from the factory. I didn't bother attempting the warranty as I'm fairly confident it has expired on the accessories. Purchased an after market regulator, set everything up, sharpened me a 3/32, 2% Lanthanated electrode, cleaned up a nice piece of mild steel for practice, and I'm ready to start making crappy beginner welds. Well that's what I thought.....About the best arc I can produce resembles something that the sparkplug on my lawn mower puts out. I tried all kinds of settings, checked for good ground with the clamp, cleaned the metal, no luck. Tried with foot pedal and without, still nothing. Am I missing something? Anybody got any ideas they might offer. I put a letter into customer service a few minutes ago, but I thought I'd also post here. Thanks in advance for taking the time to read this.
