Gas-air injection torch “DONMET” 259 is intended for heating up to 300° C products made of ferrous and non-ferrous metals, non-metallic materials, as well as for melting the surface of bituminous roll material in the production of waterproofing in various buildings.
The torch is also used for heating when bending plastic pipes, drying reinforced concrete panels and brickwork.
Used fuel gas: propane-butane (P), natural gas, methane (M).
The main parameters of the the torch according to the requirements of ISO 9012:2009 “Gas welding equipment for gas-flame processing. Airaspirated hand blowpipes. Specifications and tests”.
Can be used for roofing work, drying of reinforced concrete panels and brickwork, burning off old paint, repairing cable lines, for burning weeds, disinfecting surfaces in agriculture, etc.
► intense steady flame even in a thunderstorm
► ensures complete gas combustion
► optimal length for roofing work
