Crawl out from under car. 13.Reset wire speed 14.Crawl under car 15. Notice amps too low 16. Crawl out from under car. 17. Reset amps 18. Run a bead 19. Crawl out from under car. 20. Put everything away Here is how I gas weld in 8 easy steps: 1.Roll cart to car 2. Unroll hoses 3.Set gas 4.Crawl under car 5. Make any needed adjusments with knobs on torch 6. Make bead 7.Crawl out from under car. 8. Put everything away I'm much more experienced and comfortable with a gas set up and that's what I prefer to use. If I had the hours on a MIG I have with a gas set up, I'm sure the result would be different. One big advantage to the MIG is it can be done one handed, which has some real benefits at times. Both have methods have their place as does Stick and TIG welding.
