Naw you can weld thin metal with arc. It is not easy. You have to use small diameter rods, low amps and know what you are doing. To high amps + thin metal = blow hole. I was a professional welder for years welding tig, mig and arc. Hands down I would use mig. Not saying you can't blow a hole with mig but if he was welding on my rig he would use mig.

these days the only thing arc welding is used for is outdoors, in the wind or high altitudes because the MIG gas is ineffective in those situations. in every other situation MIG is superior.

any of you Oregonians ever do the bunji tower at Mt hood ski bowl? this will make you **** your pants if you have but it was recently inspected and failed with flying colors, the thing is only a few years old and on the verge of falling apart because it was built with a MIG welder.

I totally agree, but most people aren't setup with an adjustable heat controller on their torch or can weld in awkward positions such as what he is trying to do.

I have a Miller Synchrowave 180 that is all setup for this type of stuff and a Millermatic 135 Mig that is more forgiving with large gaps, not-so-clean sheetmetal and awkward positions.

Regardless of the method the skill of the man wielding the welder makes the real difference.
