[QUOTE="ps2thtec, post: 340859, member: 3335"] The regulator is only on the oxygen tank. Gas is direct line . You adjust the valves on your torch. Might be tough to see, first pic is 5lbs oxygen on with valve open up on torch. Small cones on outer of flame. After melt happens i turn torch knob down to get more of brush flame (so you don’t over burn the gold). you didn’t say if you do fast burnout? Putting ring in hot oven? I like to do that at 1450F. After 30 minutes to burn out residue, turn down to 1250 F. After 30 minutes, time to cast! [ATTACH]39396[/ATTACH] [ATTACH]39397[/ATTACH] [/QUOTE]
