What is considered thin 3mm and less?

Hi Dave , that's about right , even heavy steel plate will warp if you are not careful about how you weld it . we do a lot of 1/2"-1" plate and i-beam for the mines and the test site .We have a "Miller Bobcat" on a truck for the off-site jobs
That's the reason for tig welders really , the small thickness is easier to work with using more concentrated heat and smaller welds .
The mig makes it easier for almost anyone to weld sheet metal , tubing and such .
The stick is still the most heavy duty and hardest to master for most people , but like everything else it's mostly practice and patience .
