Try this.

turn on both bottles, torch valves off. Set oxy regulator to 35-40 psi, set act. reg to 7 or 8 psi. Open the torch valve for the act. enough to light the torch, open the oxy. slowly. Give it more act, and oxy to balance the flame, very small, very blue flames right at the torch tip. The rest of the flame will be blue/orange. When you hit the torch trigger, these small blue flames shouldn't get any bigger, if they do, you don't have enough oxy, turned on the torch valve. good luck.
