What do you use as a guide to cut the corrugated sheet? and do you use it to cut square tubing and the like also?

So even though my compressor tank is 150PSI (or whatever - high anyway) it needs to be reduced to the correct PSI via a regulator.

Definitely running it through a regulator. From memory it was about 50psi - but whatever it said to use in the instructions.

Is the success mainly in the setup/equipment, or is technique critical?

I need to spend some time and have a decent play with it now that I've got a good supply of tips, as when I first tried I'd burnt the guts out of 3 tips in a few minutes and gave up.
