Oxy-Propane - 5 psi fuel - 6 psi oxygen w/oxygen concentrator
Victor type TEN tip - size #4 (.073") For size reference the nozzle is 1.5" long - O/P typically produces a longer inner cone than O/A, otherwise they look almost identical.
The image below was taken about 4 years ago. The coupon is .200" (5mm) thick and brazed with off-the-shelf, 64kpsi LFB in a single 15 second pass using a #4 tip fed with Oxy-Propane w/oxygen concentrator. It was then allowed to cool and bent in AWS coupon bender.
