Thread: Welding stainless

Tweet

If you really want to get technical it depends on which type of transfer system your welder is. There are three types each having their own weld dependencies. I can get into it if you want, but not really needed for what you are doing. For your project, being small, and non repititious you are fine with 100%Argon, 99% argon/1% O2 (or 98/2) or a trigas of helium/argon/co2 at 90%/7.5%/2.5%.

Basically for your application and amount of weld you have to do, what ever gas you have will work fine providing it is one of the three above. But as stated above, If you have someone that can TIG for you, that is much better on stainless, especially the small area you are doing.
