I too am working on a small car project.
I purchased a Mig welder, tube bender and notcher with the intention of using drawn tube steel. While the Mig works well (point and shoot), I’ve found that trying to weld with small diameter tubing takes some practice, and doesn’t always give the finish and control I’m used to with gas & stick.
My new design is leaning towards an aluminum monocoque design, as I’ve been having good results cutting aluminum on my CNC routers. I know that I’m going to have to look at a large Tig with cooling & long duty cycle to handle the heat and long run time. |
