Nothing wrong with using a torch. In fact, it's superior to a MIG in most body panel applications as it doesn't deposit a bunch of filler rod on the surface. Far easier to see what's happening as well since you don't need a dark lens. It also produces an easier to work weld. Welding with gas and thin bailing wire results in a very easy to planish and file weld.

Plus you can use it to shrink, cut thick materials, remove stubborn fasteners, etc... It's a very versatile tool and I always recommend it when people ask about a welder for sheetmetal work.

I will look into that. Thanks for the tip. I did notice that the gas kicks on about .25 Sec. before the wire starts to feed. I will need to monkey with the welder some more given the new information. I may just get a Hack-A-Day post out of this :lol:

It's been 30+ years since I used a torch. Even then all I did was brazing. Is gas consumption high while welding panels with a torch? What size bottles are recommended for "hobby level" panel welding?

I generally set my gauges to 3psi, so not a lot of gas is consumed.

I’ve seen torch setups for not much money on Craigslist. I imagine smaller bottles for the hobbyist. I use mine all the time. Another bonus is that you don’t have to install 220 and it’s portable. No power required.

@Bulli Klinik:
Do you, or anyone seeing this, have a recommendation on reliable hobbyist torch brands? I don't want to cheap out or go overboard. I suspect Harbor Freight is not the place to buy torches.

I have a Victor torch I bought 20 years ago. It was pretty reasonable. I recently saw a complete setup with extra regulators, lots of tips and bottles on Craigslist for $175. That’s less than the cost of bottles alone. I generally weld sheet with 0 or 00 tips. I’d buy a name brand so you can get tips.
