I have a oxy/propane setup for cutting/heating/welding.
I just can't find any info on where to start with pressure settings for cutting and heating at the oxy and propane regs and at the handle.
Got any starting advice for me?

propane anywhere from 10-15, whatever.
Oxy, depending on tip size and material to be cut, run it at 20-40 depending on how thick the stuff is. I've used propane all my life and with the right tips and some experience, its not too bad.
You run a little more gap from flame to tip (vs acetylene) when you adjust gas before putting the oxy to it.
To set it you might have to have it up against a piece of metal (by set I mean you have the gas on, put it against the metal and THEN turn oxy on)
Set the preheat blue tips the same as an acetylene rig, with the cutting handle open and playing with the oxy knob, assuming you put your gas in the right place to start.

All my previous cutting was with oxy/acety. I bought this setup and just haven't had reason to use it yet. The gasses are in the right places. I'm actually going to use it to heat and bend a 3/8" walled tube but don't have a "heating tip" I have a #1 and #3 cutting tip. I figured I would use the #3 and dump a little more propane into it.
Sound like I'm on the right track?
Thanks.

Adding more fuel will cool the flame, if that's what you want, yes, you're on the right track.
