Have a holw in the tailgate of a blazer. picked up some light (not really light but quite a bit) reading material on welding, and most say oxyacetylene torch should be the first purchase for all it can do. Any comments? I know an exhaust guy who said he'd teach me to weld this way, I may take him up on it. Anyway what torch is recomended? I'd rather go nicer than crappy. . Also if anyone in the DFW area know gass suppliers let me know.
