The all new SCRAPING NOZZLE 170.119 from Leister for UNIROOF 700 & 300 improves the quality of welds even further. Leister has developed a brand new patented nozzle design which launches with the UNIROOF 700 and UNIROOF 300.
This new scraping nozzle creates a 25-30% larger surface area within the weld, a 12-16% wider weld width and produces a much stronger and more robust membrane weld with higher tear resistance and with minimal scorch and spit out of slag on PVC. Not only does the new scraping nozzle improve the physical weld quality it also allows for faster roof membrane welding speeds, lower temperatures and at a lower voltage than previously possible. The new design also virtually eliminates the need for solvents to clean the nozzle, better for productivity and for the environment.
