That is a pretty good tip for fussy jobs in general using other materials as well, not just stainless.
One of my little stainless 'tea strainers' that I use for holding tiny parts in my ultrasonic cleaner had popped the spot weld apart holding half of the basket to the scissor frame. The arms of the frame are only about 1/32" in thickness. Pretty thin material. I decided to tig braze (Silicon Bronze) the basket back on so as not to melt away the arm with too much heat. The smallest diameter rod I have is 1/16" which is twice as thick as the arm and would have been hard to get to flow before the arm melted away.
So instead I used some .035" mig wire for filler which was a good match for the thin metal of the frame and I didn't have to deal with a huge blob of bronze coming off of the end of a 1/16" rod.
