Try going for a wire of 023 inches when welding sheet metal.
Best gas for welding sheet metal.
But keep in mind that thinner material like sheet metal should not be welded with flux cored wires.
Forney 30705 e7018 welding rod.
Use a shielding gas that contains at least 20 carbon dioxide balance argon.
If you will use spray transfer then got with not less than 20 carbon dioxide.
If using short circuit transfer in thinner parts using 100 is acceptable but will generate more spatter.
So the question is.
Welding of carbon steel can be done with carbon dioxide alone and it produces the deepest penetration the most smoke and the roughest weld.
How to weld auto body sheet metal with a tig welder.
For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.
The high carbon dioxide content does a good job of welding through the zinc coating.
Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less.
There are other mixtures that work well depending on the type of welding that will be done.
Welding gas for stainless steel while choosing the shielding gas for mig welding stainless steel welders usually prefer a mixture consisting of argon 98 and co2 2 while some prefer to use the gas mixture of helium 90 argon 7 and co2 2.
If the metal is around 3 16 inch long we recommend you to use the stick welder.
Tig welding sheet metal.
Finally if you are welding sheet metal with solid wires an electrode positive one is recommended or one with reverse polarity.
Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900 s.
Stainless steel are used in applications such as hvac automotive mobile machinery guards and cabs and small parts as well as stainless steel food service and processing.

Tips for welding sheet metal with mig or tig.
Why would i ever want to gas weld anything.
While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.

How thin is this metal.
Because it will have you a lot more control over.
Many brands make these welding rods.
Carbon steel and 18 ga.
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.
And this welding process is still very popular today mainly because it does not require much equipment and does not require power.
The most widely used mixture is called c25 and that is 25 carbon dioxide and 75 argon gas.
The stick welder is available for getting the right finish and doing more than rust removal from the surface of this thin metal.
