Rudy,
I'm no expert but if you are planning to use the welder for your TR it makes
most sense to acquire a MIG welder. The MIG can handle the thinner sheet
metal as well as some of the thicker steel (I think 3/8ths but don't quote
me) and is also less expensive to buy. I have a Hobart 110V MIG welder that
works really well - not sure if the TIG does 110V. The reason for inert gas
is to prevent weld contamination - I think by oxidation. The gas flows out
over the weld and protects it. Flux core (gas less) wire does the same
thing but not nearly as well and leaves messier welds. I know because I
have done it both ways! I think the gas is a compromise mixture of argon
and CO2 in some ratio.
I think that using an arc welder on the sheet metal would be a huge mistake
as it would be very hard to keep the metal from burning through - especially
if you are a beginner.
There are some very experienced ladies and gents on the list who might be
able to recommend some good web sites...
I got my MIG (Hobart Handler) for somewhere around $300 and I love it.
Wayne
