I purchased an 82i machine early this year to go with my DIY plasma table. I've had everything up and running for a couple weeks now. And have mostly been working on dialing the table in. Its a 5x5, lots of good parts. So today I was actually cutting out some signs for friends and to sell. I have gone through about 6 tips during the tune in process, cutting up a couple 4x8 sheets of 16 gauge and 1/8". I attributed the short lasting time to my tuning things in. Well i did one cut early today and lost a tip, so I replaced it and then cut a couple large signs, on my 4th cut I had another tip go while on the perimeter cut sadly. But it went bad, lost the outer and inner as well. I couldn't even get inner off without twisting the threaded portion of the torch off.
So my questions are, can I replace any parts on the torch end or is it only sold as one complete piece? And where is everyone buying consumables at? Are they interchangeable with any other brands? Who makes this machine torch, Everlast or subbed out to someone else?

Pics to show you the problem. Not sure why pics so big,,,I selected for forum.

Sign I cut earlier, came out quite nice
