The torch with forced air supply;
– heating ferrous and basic metals for surfacing and welding
– elimination of weld metal depositions and tensions;
– heating of interference fit unit at assembly and disassembly
– casting mold, concrete panel and brickwork drying
The welding torch “DONMET” 275 is designed for preliminary heating of metals before surfacing and welding in metallurgy.
The welding torch operates on an air-gas mixture using natural gas (methane) as gas fuel.
The welding torch basic parameters conform with ISO 5172.
