Gas or liquid fuel torches are used for welding of bitumen and polymer-bitumen materials, preparation of bases (drying, warming up of floors and roofs) during installation of waterproofing materials and other construction work that are technologically connected to the use of an open flame with heating of the surface to a temperature of up to +400°С. The range includes a simplified versions of torches and professional equipment to perform specialized works.

The jet is used for modernization of welding equipment Varimat so that it can be used for hot-air welding of bitumen materials seams. The jet nozzle is designed for warmed air supply to the place of bitumen materials connection. Using of the nozzle and wide steel roller allows making a seam in overlapping of roll-fed bitumen materials not less than 90 mm width with binding agent flowing out of the seam. This method of welding increases the speed of roof covering arrangement signifi cantly (by 1.5 times) in comparison with traditional methods of padding with the use of standard propane burners.
