BITUMAT B2 Flameless Bitumen Welder

The BITUMAT B2 Flameless Bitumen Welder by Leister is used specifically for the flameless welding of modified bitumen. Compared to welding with open flame, only one worker is needed to effectively weld modified bitumen, making it safer, more efficient and more economical. The standard wide nozzle provides seam welds that are much more accurate and constant than flame welding. With it’s ability to weld seams up to 12 meters (39.4 ft) per minute, you will save time and money by reducing your operating costs.
