MIG & TIG Welding

What is the main difference between MIG and TIG welding?

The difference between the two is the way the arc is used. MIG (metal inert gas) welding uses a feed wire that constantly moves through the gun to create the spark, then melts to form the weld. TIG (tungsten inert gas) welding uses long rods to fuse two metals directly together.

Which is better TIG or MIG welding?

TIG welds are better for thinner metals and smaller projects because they produce precise and clean welds. MIG welds work well with larger projects with thick metals that need longer, continuous runs. Control: TIG welders need to have experience with timing and balancing materials in both hands.
