Need tig welding advice
I have been wanting to learn to tig weld for quite some time. So recently I bought a used but very nice Lincoln tig 255. The adjustability on this thing is almost infinite and thats probably making it harder.
I've been practicing on 1/8" steel with my machine set on 2-step and have had pusler on and off with mixed results. Been trying everything between 40 and 50 amps. has foot pedal control. Using aircooled torch. Problem is that it seems to be overheating the tungsten after a couple minutes and I get erratic arcing. using 3/32" lanthanated tungsten. I'm grinding it properly too.
So far I've made some decent amatuer looking welds. Hoping you guys can help me take out some of the mystery.
