TIG Pros: very neat welds, no spatter ,penetration can be seen,no clean up needed of welds.
Cons: machine not cheap, slow,akward in tight spaces, may need 3 hands for tacking,gas not cheap.

MMA/arc/stick Pros: very strong ,cheap machines,can be used outside.
Cons: very messy, lots of spatter, slag on welds,damp rods if not stored correctly,easy to blow holes in tight gauge material.
