Not a lot of confusion, just different discussion from different sources. Both use an arc, both use a stable shielding gas (many times the same type of gas too), neither make use of flux due to said shielding gas, and both commonly (MIG always) use a filler material added to the arc to create strength in the weld. The book I used for my welding classes lists TIG as a GMAW process that is also known as GTAW. The more acronyms you throw in the mix the more confusing things get. Tungsten is a metal and that is where the M comes from in GMAW, so I don't feel bad about saying what I said. If the world has changed since then and dropped my views, I'm happy to change my ways.

While this thread has remained educational, it has completely derailed off topic, which is so strange for CD...

That being said, if I was the OP I would make use of that welder and build a steel chassis. Every time we build an aluminum chassis, we swiss cheese the thing for days to make weight. Every time we build with steel we come in comfortably under weight.
