Tom,

I wouldn't use MIG (or TIG for that matter) since the tank's covered 
with zinc. Zinc fumes are very bad for you. Brazing isn't too terribly 
expensive to get started with. You can get a portable gas welding kit 
for around $75 (they use small tanks like a propane torch so they don't 
last long). $10 will get you a bunch of brazing rod. Also, you can buy a 
torch and regulator set for about $150 and rent the gas tanks from a 
welding supply store.

Besides being able to braze, the massive amount of heat a gas torch set 
can put out will help free stuck bolts (or cut through rusty exhaust 
parts) in a hurry. There's a reason they're sometimes called a blue 
tipped wrench.
