For those of you who use Oxy/Acetylene setups for brazing, What do you set your pressures on and what size tips are you using for typical residential work? Lately, Ive been having trouble with my torches. I'm not sure if its related to the things I have asked or if I may have something in my tip (which came with the torch set). I'm looking for a new tip but rite now I use a #3 Harris tip and set my Acetylene on about 5 psi and oxygen at about 7 psi (both psi's are under draw. Any feedback is appreciated. Thanks.
