A question about welding and sheet metal, as I am contemplating purchase of a welder.
I welded on my truck's sheet metal using a MIG, which worked fine. My impression of TIG however is that is generally allows for more precise work, smaller welds - most bicycle frames these days are welded by TIG and they can have some pretty thin tube wall thickness, so that suggests that for thin sheet metal the TIG would be better.
I notice that TIG is also more versatile if you want to weld aluminum, stainless, titanium, etc., while MIG is pretty much used for mild steel, though it can be made to work on aluminum. I've been noticing you've been using brazing rod with your TIG, which opens up another avenue of possibilities i hadn't even been aware of before.
So, if you were to buy a welder, aiming for versatility, would you buy a TIG or a MIG? It used to be the cost was a major deciding factor, but I notice there are some TIG welders for $699 or so on Eastwood's website. So, if we could ignore, cost, would you recommend TIG over MIG, or not?
Thanks!
