Ruger army sight conversion

Theres several things welding stainless the wrong filler and it gets hard and brittle, or soft and gummy... The other is depending on the welding being done, TIG would be my with a argon mix flux would be my choice .

What would you recommend for a filler rod? 309L, 312L or something else?
Why an argon mix? Why not straight argon?
Why a purge box?

I'm new to TIG welding so I'm kinda curious as to what your thoughts are.

Would need to know what the rugers stainless is to recommend a rod for filler. The wrong filler can leave welds that don't match the piece, and are hard or brittle. Ive always used the argon mixes. They just seem to give a better weld. The purge box shields the weld from atmosphere and holds the gas flux around the weld better giving an inert environment. Welding stainless pipe in the food industry we filled the pipe with argon and a flow when welding we got a complete weld with no flash thru on the inside same nice even weld as the outside. Shielding the welding with blocks keeping air away makes for a much better weld with few inclusions. Another welders trick is use a u shaped groove instead of a Vee. its easier to get into the bottom and makes for a more complete weld.

SASS does not require NON stainless firearms.
