Gas metal arc welding gmaw is an effective method for joining light gauge metals such as carbon steel and austenitic stainless steel.
For sheet metal i use ine welding wire and it is just as good as their flux cored wire if you want you can grab one here.
For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.
Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less.
