Say, I have a Powermaster 256 and I mainly need it as a plasma cutter but I have had a lot of trouble with the cutters. The one that originally came with the welder caught on fire on the handle near the cutting electrode. Because the unit was a few months out of warranty, I had to buy another cable/cutter assembly. This one has the number SG-55 stamped on the plastic near the cutter electrode. It cuts fine for a couple of minutes and then it loses efficiency very quickly. The electrode erodes very quickly.
When I look at the plasma cutter expendables, I don't see a cutter that looks anything like the one I have. Can I get expendables for this??? It's only about a year old. Is there another cutter/cable assembly that works better than this??
I had a heck of a time getting the right cutter/cable when I ordered the one I have now. At first, even after sending a picture of the connector plug, I was sent the wrong one which I had to return. Mine has a separate 7-pin connector rather than the connector which is integrated into the main cable plug. I sure hope you can help me -- I've pretty much had nothing but trouble with this unit from the start.
The original cutter which caught on fire but which worked pretty good for a while had a little metal guide on it to maintain the proper distance between the cutter and the work-piece. Are these available for this SG-55 cutter I have?
