Air Gas Torches – US
BELCHFIRE Torches are used by Welding Fabricators, Foundries, Cast Iron, and Marine Service Shops where Pre Heating and Post Heating are Required for Ladle Heating, Crucible Heating, Preheating Metal, Welding Cast Iron, Nickel Welding, and Cast Iron Crack Repair.
Quick Info: BELCHFIRE © gaseous fuel plus air torches burn all commercial LP type fuels or natural gas combined with 50 – 150 psi compressed air.
No orifice changes or modifications are required when changing from one gas to another. They are instant lighting and have a completely adjustable flame.
Backfire is impossible because air and gas are mixed externally. The combustion chamber is phenomenal because it is of thin and light, heat resisting material which glows at a bright red. This bright red glow is radiant heat which reflects back into the air – fuel mixture, thus enhancing the combustion process. Also, the many louvered openings permit a parallel flow of secondary air (6 volumes of sec. air to 1) aiding combustion and reducing noise level. May require manifolding of LP fuel bottles or larger fuel source.
