thanks for the link the parts are like just under $80 like a $20 difference from the welding supply near me that will buy a new liner,
i talked to the guy i got it from he said he won't give me any money back towards the parts because he said it welded fine for him and he didn't know nothing about it, BUT he did say he would give me a full 3ft tall bottle of C 25 for $75 that is a bought tank so i told him i would take it
Sounds like an 80' cylinder. That's not bad. I just wonder if he had someone switch from high to low while welding.
