I am having a try at DC tig brazing today
im getting alot of soot
using what should be (ebay buy) some Sifsilcopper No. 968 Tig Filler Welding Rods 1.6mm 100% argon around 80 amps
it does clean up ok.
Not touching down and even the electrode is getting sooty. ive turnedup the gas flow and tried even turning it down. tried from 5lpm up to 30 lpm also played adjusting amps up and down as well as speed
test piece is a bit of mild steel box section 1.5mm thick
