Looking for others using this unit. I am a noob and may need a few part numbers as time goes by.

Wow I’m surprised... No one has a 125? Must be rare. :) (or really old) Lol

I have never had one of these welders, but they are fairly common. There are two or three versions out there, but I think they may all use the same consumables. You can probably pick up tips and nozzles at most well stocked hardware stores. Good luck.
