As far as I know they only have the one Plasma machine. PN#95136 At the full 40 amp 60% duty cycle, I can't remember if it was the 10 or 20 amp setting it was 100% duty cycle. I read a whole whack of reviews besides the HF ones, and it seems to be getting a pretty good feedback overall. Also read in a couple of different sources that it may be a Hobart clone. Nothing wrong with that if that's the case. Consumables from HF are a bit pricey. The torch head is a Trafimet S45 and you can get parts quite reasonable on Ebay. HF tips 28.00 for 5 and 14.00 for 5 electodes, found a source on Ebay that sells 100 of each for 68.00 bucks. Should be a lifetimes worth for me. Wire tip guards, swirl rings, wheeled carrage, (also used as a circle burner as well as for straight cuts along a guide) and bunch of other parts are available on Ebay. I'm ordering the spare parts to have on hand, plan on keeping this one for awhile. Not trying to advertise for HF but I think I can recognize a decent deal when I see one. $649.99 on sale...$599.99 if you have the Track Club membership. Mine came with a molded welder plug already on the cord, most HF literature said you have to add it on yourself, not the case. Saves a few bucks again. Everyone was impressed with it today when we tried it out, the fact that it's inexpensive, compared to a lot of them out there is real bonus. If it continues to perform like it is right now I'll be doing the happy dance for quite sometime.
