Yes, for TIG. TIG is always 100% Argon (steel, stainless, Ti or Al) unless you add Helium for pentetration

im sorry let me rephrase this.....

100% argon for mild steel mig welding?

so 100% argon is ok for mild steel?
thanks so far for the help

went to the weldshop to fill my tank of argon for my mig welder and they gave me a tank of 75/25 mix.....

i own my tank.....my question is can i use this 75/25 mix for tig welding too?

thanks joe
