Thanks for the input. I'm going with the sears $300 gas ready wire welder which can use flux core. Local gas supplier sells large tank (forgot size, about 5 feet tall) for $150 full at purchase. Also dropping 50 bucks on a better helmet than comes with the sears kit. Plans are to strip my 86 heavy C20 to frame, sandblast, fill and paint frame than rebuild. Very long list of what's to be replaced. The present 305 engine and worn out 4.10 rear will go. Anyone wants some long stories, ask why I'll keep this old friend. Short version: 100% reliability. 265,000 mi. auto tran and engine both rebuilt one time.
