I am interested in teaching myself how to weld with gas. O2 Accetiline, not MIG gas.
I have a mig welder that I am sort of competent with. Is there benefit to welding with gas over MIG, or am I going to find that if I buy the tank set up, I'll never use it over MIG. Zach |

There are many good uses for a gas setup. It was the second thing I got after a wards stick welder a long time ago 1968. Get the double diaphragm regulators if you can they last longer. The trick it to turn the regulators on REAL slow to avoid blowing the diaphragm out. I use it a lot for heating thick metal to bend easier. I cut thick steel with it. I don't have a plasma cutter yet as i'm pretty sure I don't need one for the type of fabbing I do. My friend that fabs has one and he doesn't think I can justify the cost for the stuff I do. I welded a rusted out 42 jeep tub up with a torch even though I had a mig just to see if it was better. There is way less bulge in the weld bead but there was more heat put in the original metal which I think made the metal lose some of it's strength and it made it start rusting almost the next day after it was welded. You can weld aluminum with a torch. Check out John Kelly's site ghiafab I think, he's on here I think as a vender, I just ordered a new dvd from him thats his latest. He does all his auto sheetmetal with a torch I think.
