Leister Technologies AG will debut its new UNIROOF E 40 mm automatic welder at the International Roofing Expo. With its 1.6-inch overlap nozzle, the UNIROOF E 40 mm provides upward of 2900 watts of power with only a 13-amp current. That’s 25 percent more heat than its predecessor, the UNIROOF E. The new nozzle, combined with additional weight over the contact roller, ensures high-quality, uniform welds across roof sheeting made from TPO / FPO, PVC, ECB, EPDM and CSPE.
