i am doing some body work and need to know is welding better than brazing? 1985 gs 12A

what exactly are you doing? welding and brazing are two different operations with different aplications.

Weld......use either a spot or Mig type unit.

Brazing is more like soldering or gas welding with a torch.It requires a lot more heat and time........both of which are the enemy of sheet metal,which warps badly when being fused back together with a weld.Mig allows you to "tack" the pieces together in very short little burst,reducing heat transfer.

So back to the question.........what are you doing???? It makes a big difference in what the answer is as Steve has pointed out.

i have a few small holes that need to be fixed 1" max and the inside of the wheel wells have some rust damage. I am looking to cut out and replace. I am good on an arc and a torch but have never used a mig. is the transition hard.
"should I buy a cheap mig"?

go mig with a small job like that the heat transfer would warp the metal and cause more work for you on the end

A monkey can Mig weld,its easy.Like most welding,its all in the prep.

The little 110V, inner sheild wire machines will do the job for panels and sheetmetal........but nothing beats a big roll around 240V unit, with an Argon bottle and some 035 wire.You can always turn a big machine down,but you cant turn a small one up!

MIG welding your holes would be the best choice.

+1 to Steve! And when you have a ton of crap to waste, its hella fun to play with!
