Flame Tech HD 3 Heavy Duty Inferno Heating Head, MAPP/Propylene, Size 3, Tested in The USA

FlameTech Inferno heavy duty head is designed to operate with MPS gas, Propylene, propane and natural gas. It is machined from solid bar stock. Internals are press fit and Pinned with a large Brass pin to prevent separation during backfire. Large heating assemblies require high volumes of gas to keep Flames burning properly. "Starving" the flame will overheat the tip and cause a backfire or flashback (hissing sound inside the head.) If additional flow capacity is required, use a manifold system of sufficient size to supply the necessary gas volume. Note: heating heads marked with an asterisk must be used with 3/8 inch ID hose and a heavy duty torch handle. Specification: head size: 3; natural gas/propane pressure (psi) min-max: 15-25; oxygen pressure (psi) min-max: 70-100; natural gas/propane consumption (CFH) min-max: 150-200; oxygen consumption (CFH) min-max: 350-460. 1 years of manufacturer warranty.
