I just bought a 210ext that is 2 yrs old. Guy only ran one small tank of argon. Couldn’t get the hang of tig. The machine is great. The question is, “do I get the remainder of the warranty if I need it ?” I don’t anticipate any issues, I use a 325ext and a 250ex at the shop I help out at. These machines get used a lot and never break down. Thanks
