Got a pressure regulator installed for the Anealeez. There's a good write-up on Giraud's, but they use a different torch.
No big surprises:
To answer the burning question of why:
Internal bottle pressure will vary with temperature. As propane is drawn off, the temperature and pressure will drop. You might notice this on big batches or when using a summer "recipe" in your cold garage. At 90F bottle pressure is 150psig, down to 64psig at 40F.
As-purchased, the torch uses an inlet orifice to reduce bottle pressure, then the torch valve works as a second, adjustable, orifice. This works well enough for most tasks, but orifice flow depends on upstream pressure. Regulators hold the pressure constant and eliminate variables.
No big surprises:
- Hose threads are straight M10x1
- There's an orifice at the back of the torch that must be removed. This necessitates removing the check valve it depresses.
- The regulator is 0-60psi. Initially I tried a small 0-20psi and had difficulty flowing enough gas to light the torch. For consistency, run the torch wide open and adjust pressure to meet your needs.

- Pick a gauge with 1/4 NPT threads, I already had this one.
