Is the tank freshly filled?

There's no hard and fast rule that says the propane MUST be at 5 PSI. You indicated that the problem is less at higher pressure, try setting your pressure at 15.

Control the pressure further with the knob on the torch. I remember a conversation with Peter at Nortel (he's the guy who built the torch) - he indicated to me that the pressure provided to the torch is basically not worth worrying about - set it as high as you need to in order to provide an even flow of gas, then control how much fuel is burned with the needle valve on the torch.

With a higher pressure, you will have more flow and the valve will be more sensitive, but it should not affect your beadmaking ability. You don't have to worry about your oxygen supply, follow the usual method of setting your cone length and adding enough oxygen to the mix to get a neutral flame.
