It's usually a mistake to try to compare the pressure and results of someone else's burner/forge combination with yours.  These DIY builds lack the precision to do reliable apples to apples comparisons.

 

Thank you, I was thinking the same thing, I also have my pressure gauge right at the tee at the top of the air fuel mixer, downstream of the needle valve, I think most people have their pressure gauge between the tank and the needed valve from what I have seen. Odd thing, i never adjust the needle valve just the pressure on the regulator. 

They make VFDs that are  single phase input and 3 phase output, you can buy them on ebay for 100 bucks, i use one on my drill press and belt grinder.

I wouldn't worry about pressure,

That is what I was assuming seems pretty tough to build much pressure with a full port orifice, I have only run naturally aspirated forges Ron Riel style  Burners so its new to me. I think ill try to crank it up to forge welding temp, Which I have never forge welded so that will be interesting.

Thank you!

Newbie here.

I built a new forge with a ribbon burner burner is 8" x 4" with 20 each 5/16" holes fed by a 2" supply pipe. I read most guys run at 1 PSI Propane for forging and 5-7 for forge welding.

I cranked up the forge last night to see what pressure I could get, I never even registered 1 PSI when it started choking due to to much fuel. 

the gas supply is 1/4" pipe and the air fuel mixer is a 1/4" 90 elbow in the 2" supply pipe. I am wondering if I will never get those pressured due to the large orifice size of the gas supply or if my blower is not adequate.

I do not actually know what my temps are I guess I need to crank it up and see if it will forge weld? 

any thoughts?
