Roof stays sealed using Leister.

First rate quality is called for when laying and welding roofing membranes. After all, small errors can have expensiverepercussions. That is why professionals rely on Leister and our line of precise, durable and easy-to-operate devices. We offer a variety of hot-air welding machines, hand tools, and a broad range of accessories for welding PVC-P, TPO, ECB, EPDM, CSPE and elastomer bitumen roofing membranes. As the worldwide market leader in the hot air plastic welding industry, Leister knows what roofing professionals need to succeed.

VARIMAT V TRIAC DRIVE PID

This tried and tested automatic welding machine for roofingmembranes is now better than ever: the new VARIMAT V also displays voltage and welding seam length. A model specifi-cally for overlap welding of elastomer bitumen is also available. ? Overlap welding of PVC-P, ECB, EPDM, CSPE and TPO roofing membranes as well as elastomer bitumen? Easy welding, also of homogenous and thin roofing membranes? Wrinkle-free welding up to 5 m/min? Patented pendulum pressure roller guarantees uniformpressure also on uneven surfaces? Digital display of set and actual values of welding speed andtemperature? Constant temperature and speed independent of voltage fluctuations and ambient temperature Horizontal, vertical, diagonal. This tried and tested semi-auto-matic welding machine can be used universally. The increased welding speed compared with manual welding gives rise tohigher productivity. ? Overlap welding of PVC-P, ECB, EPDM, CSPE and TPO roofing membranes? Faster and more efficient than hand welding ? Small and compact ? Steplessly adjustable speed for high welding seam quality? Can be used in the most confined spaces? Different welding seam widths Technical Data
