Does it matter what type of welder is used on exhaust system?

The biggest thing in welding is what to metals your welding together and what your welding them together with.

While to can use nearly anything to put nearly any to metals together, the quality and longevity could suffer greatly if your not paying attention or caring.

If you take the time to goggle what can and can not or should not be done there is always a welding shop to do it for you.
