I’ve had good results brazing using a Bernzomatic TS8000 Mappro torch kit from Home Depot. I get the brass filler wire from Walmart in the craft section where they sell stuff to make bead bracelets. For flux I use 20 Mule Team Borax from the laundry soap department also at Walmart. Works great on stainless steel.
