Additionally, it is used for professional welding, shrinking and molding various thermoplastics. The two-sided air filters of the TRIAC ST can be easily removed and cleaned. This ensures an optimal air supply and maximum performance. As a successor of the TRIAC S, the ST combines a new, highly robust engine with current technology and modern design in a handy heat gun.\u003c\/p\u003e\n\u003cp\u003eCompared to the design of other heat guns, the proven bar-style heat gun enables welding above the head, on the floor and in narrow areas. The ergonomic, two-component handle and its optimized center of gravity provide an ideal grip, even for longer periods of use and under difficult conditions. When in use, the actively cooled, protective tube ensures continuous safety by protecting against burns. The carbon brake also protects the heat gun from overloading.\u003c\/p\u003e\n\u003cp\u003eThe extensive range of accessories with over 80 attachment nozzles practically make this heat gun a universal device. The TRIAC ST is already the seventh generation of Leister?s revolutionary line of TRIAC hot air tools. Decades of experience packaged in a modern design, manufactured with Swiss quality: The TRIAC ST is a robust and reliable tool.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Leister","offers":[{"title":"Default Title","offer_id":47636968931477,"sku":"141.228","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/1998\/6581\/files\/TRIACST.avif?v=1785379590"},{"product_id":"leister-uniroof-700-automatic-hot-air-welder","title":"Leister UniRoof 700 Automatic Hot Air Welder","description":"\"\"","brand":"Leister","offers":[{"title":"Default Title","offer_id":47636968964245,"sku":"165.835","price":0.0,"currency_code":"USD","in_stock":true}]},{"product_id":"leister-uniroof-300-automatic-hot-air-welder","title":"Leister UniRoof 300 Automatic Hot Air Welder","description":"\"\"","brand":"Leister","offers":[{"title":"Default Title","offer_id":47636969029781,"sku":"168.635","price":0.0,"currency_code":"USD","in_stock":true}]},{"product_id":"leister-varimat-300-automatic-hot-air-welder","title":"Leister Varimat 700 Automatic Hot Air Welder","description":"\u003cdiv class=\"product_desc\"\u003e\n\u003cul\u003e\n\u003cli\u003eHigh welding reliability due to more contact pressure\u003c\/li\u003e\n\u003cli\u003eTracking accuracy thanks to variable transport axis\u003c\/li\u003e\n\u003cli\u003eNozzle swivel-in mechanism for fast insertion\u003c\/li\u003e\n\u003cli\u003eVisual alarm when leaving the welding window\u003c\/li\u003e\n\u003cli\u003eFlexible voltage choose between 230 and 400 V\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eWE OFFER CONVENIENT IN-HOUSE SERVICE AND REPAIR ON ALL LEISTER WELDING MACHINES\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Leister VARIMAT 700 automatic welding machine features high contact pressure, ensuring consistent process reliability when welding thermoplastic membranes on flat roofs. Highlights include easy conversion from 230 to 400 V and an innovative swivel-in mechanism to insert the nozzle effortlessly and quickly into the overlap. The flexible rear transport axle provides for balanced handling and allows the VARIMAT 700 to track straight without correction. Depending on the application, it can be adjusted to accommodate either field seam or close edge detail welding.\u003c\/p\u003e\n\u003cp\u003eThe VARIMAT 700 automatic welding machine is designed for various applications: Whether for roof installation or swimming pool construction, waterproofing membranes are processed reliably, quickly, and economically. Truck tarpaulins and advertising banners can also be welded dependably with the VARIMAT 700. The increased contact pressure provides an advantage by compensating for unevenness in the substrate caused by fasteners, seams, or imperfections in the insulation. The sophisticated air partition concept, now separated from the pressure roller, prevents wrinkles during welding and ensures an attractive seam appearance while optimizing air flow. The Monitored Welding Assistant assures users that welds meet customer requirements and high-quality standards. If set welding parameter limits (temperature, speed, and air volume) are exceeded, the VARIMAT 700 emits an acoustic and visual warning signal.\u003c\/p\u003e\n\u003cp\u003eLike other Leister automatic welding machines, the VARIMAT 700 is also equipped with the proven Leister Quality System, also known as LQS-Roofing. This allows users to document weld quality and create GPS-supported data reports that can be saved and shared via the myLeister app. In the event of undervoltage conditions (up to a maximum of 20%), the power management system assists to achieve and maintain the required welding temperature. As soon as undervoltage surpasses 20%, the VARIMAT 700 switches off automatically, as the set welding parameters can no longer be maintained, and weld quality may no longer be guaranteed. To ensure that the correct welding parameters are set, Leister offers dependable welding profiles and a \"library\" of proven welding recipes in the myLeister app. Leister's Scandinavian customers desired an automatic welding machine to be equipped with an LED work light, so Leister engineers implemented this suggestion during the development of the VARIMAT 700. Thus, with this automatic roof welding machine it is possible to weld at dawn, dusk, or in unsuitable lighting conditions while optimally illuminating the welding zone.\u003c\/p\u003e\n\u003cp\u003eThe large, user-friendly display with rotating adjustment knob makes the VARIMAT 700 intuitive to operate. When developing this Leister automatic welding machine, input was gathered from roofers and material manufacturers and taken into consideration, which is additionally reflected in its functional design and suitability for construction sites. The brushless, low-maintenance automatic welder keeps service to a minimum, even with intensive workloads. Hybrid ceramic bearings were used for the blower motors, ensuring a long service life even under heavy loads. Delivered in a robust rolling transport case, the VARIMAT 700 can be transported easily, ergonomically, and safely.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Leister","offers":[{"title":"Default Title","offer_id":47636969128085,"sku":"174.614","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/1998\/6581\/files\/varimat700_5.avif?v=1785375884"},{"product_id":"leister-varimat-500-automatic-hot-air-welder","title":"Leister Varimat 500 Automatic Hot Air Welder","description":"\u003cdiv class=\"product_desc\"\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003eErgonomic welding due to high contact pressure\u003c\/li\u003e\n\u003cli\u003eKeeps track due to flexible transport axis\u003c\/li\u003e\n\u003cli\u003eReliable insertion of the nozzle\u003c\/li\u003e\n\u003cli\u003eWarning signal for undervoltage for quality assurance\u003c\/li\u003e\n\u003cli\u003eEasy conversion to 230 or 400 V\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eWE OFFER CONVENIENT IN-HOUSE SERVICE AND REPAIR ON ALL LEISTER WELDING MACHINES\u003c\/b\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe VARIMAT 500 automatic welding machine from Leister ensures reliable process safety when welding plastic sealing membranes and bitumen membranes on flat roofs.
