Well, I have yet another dilemma in the welding world. All coming to light now because I just came out of hibernation to start a new fabrication project, and my equipment is getting old- like me. It seems I’m leaning on you guys a lot lately, but you all usually have the answers! So, for my next issue:
I have an older Hobart Beta MIG 250 wire welder. I bought it used years ago off an old guy who didn’t use it more than a couple of times, and I take care of my stuff, so it’s like brand new. It is fitted with a Piecemaker 25A gun that too is in good shape. It needs refreshed with a new nozzle and a contact tip, but that’s all. Except…
Consumables are no longer made for this gun. No welding house anywhere has exact replacement contact tips that I can find. They all want to sell me a new gun. Well, I don’t want or need a new gun. So, I’m in search of any contact tip that has a thread pitch of 1/4”-20. If I can get that thread, I can shape the rest of the tip to fit. All I can seem to locate are M6 or 1/4”-28 pitch. I’ve even thought of forcing a 1/4”-20 die over the M6 fine threads. The rest of the dimensions of the real thing are .25 DIA x 1” L (6.33mm x 25.36mm).
The nozzle and diffuser will be another story, but I’m not there yet. I need tips! And suggestions! Anyone know of an American 1/4”-20 thread contact tip? Can/ should I booger up something else to fit?
Appreciate the help,
Mark
