Propane forge guestions

This is the forge so far


Not sure to use 2 burners or one?
This is one burner option 3/4 pipe 1-1/4 bell .035 mig tip but it won’t burn consistently I am using a 1-40 psi regulator I had it set at 5 psi it burned but don’t blow on it would go out

My smelter has a 2” with .035 mig tip at 20 psi and as far as I can tell melts aluminum in about 1/2 hr

Not sure which way to go any options
