So the question is.
Best gas for welding sheet metal.
Mig welding sheet metal.
Tips for welding sheet metal with mig or tig.
Check out our project page for diy welding projects.
For thinner gauge sheet metal like 18 or 20 gauge we suggest 023 6mm wire in your mig welder.
If using short circuit transfer in thinner parts using 100 is acceptable but will generate more spatter.
Because it will have you a lot more control over.
Try going for a wire of 023 inches when welding sheet metal.
Finally if you are welding sheet metal with solid wires an electrode positive one is recommended or one with reverse polarity.
If you will use spray transfer then got with not less than 20 carbon dioxide.
In our opinion the primeweld tig225x is the best tig welder for.
Welding of carbon steel can be done with carbon dioxide alone and it produces the deepest penetration the most smoke and the roughest weld.
Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less.
Tig welding sheet metal.
Use a shielding gas that contains at least 20 carbon dioxide balance argon.

The high carbon dioxide content does a good job of welding through the zinc coating.
For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.
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.
Why would i ever want to gas weld anything.
Holding the tip too far from the surface will cause the wire to have to come out too far to touch the metal.
The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten.
But keep in mind that thinner material like sheet metal should not be welded with flux cored wires.

The 5 best welders for sheet metal.
While wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.
How to weld auto body sheet metal with a tig welder.

The most widely used mixture is called c25 and that is 25 carbon dioxide and 75 argon gas.

Keep the stick out short stickout of your mig wire is important when welding any type of metal but especially sheet metal.
Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten.
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.
Oxy fuel or oxy acetylene welding are gas welding procedures that were invented in the early 1900 s.
