Hi guys

Little off early Ford but will use on F1.

I am a newby in welding arena. I bought an old/used Lincoln SP-100 (see pic). While practicing on old piece of sheet metal, I ruined the tip. Probably wire feed to slow or too hot...but getting off my need.

I went to Home Depot and bought new Lincoln tips. Only to find when I got home the thread diameter is smaller than my machine. Anyone know where I can find these old style tips?

I went to local welding shop and they said I needed buy all new hose torch setup.
