The Leister VARIMAT 500 automatic welding machine, like its big brother the VARIMAT 700, has a raft of new innovations and features keeping at the top of the market for professoinal welding applications.

The new design features include an significantly higher contact pressure (3kg more than the nearest competitor), ensuring consistently improved process reliability when welding thermoplastic membranes on applications such as flat roofs, swimming pool liners and waterproof covers and also bitumen membranes on flat roofs.  The range of thermoplastic material that can now be welded includes TPO, PVC, TPE, ECB, EPDM, EVA, PIB, TPU, FPO, PO and PVC-P. 

Highlights of the new design features include a redesigned and innovative swivel-in mechanism enabling the nozzle to be effortlessly and quickly inserted or removed from the overlap for faster welding and less opportunity for burning.  Like the VARIMAT 700, the VARIMAT 500 has an adjustable rear transport axle provides for balanced handling and allows the machine to track straight without correction. Depending on the application, the VARIMAT 500 can be adjusted to accommodate either field seam or close edge detail welding.  A new air dam design featuring a sophisticated air partition concept, now separated from the pressure roller, produces a wrinkle free uniform weld and ensures an attractive seam appearance while optimising air flow.

The Monitored Welding Assistant is also present on teh VARIMAT 500 and provides the user with confidence that welds will meet customer requirements and high-quality standards.  If the set welding parameter limits are exceeded such as temperature, speed, or air volume, the VARIMAT 500 emits an audible and visual warning signal. 

Leister's sophisticated Powermanagement system ensures that in the event of undervoltage conditions (up to a maximum of 20%), the required welding temperature will be maintained, preserving the quality of the weld and saving sigificant time and money by preventing any re-work.  To assist in ensuring that the correct welding parameters are used for various materials, Leister offers dependable welding profiles and a "library" of proven welding recipes in the myLeister app.

Also new for 2024 is the addition of a LED work light which illuminates the welding zone allowing welding at dawn, dusk, or in unsuitable lighting conditions.

With a powerful brushless motor, the VARIMAT 500 automatic welder is designed to be low-maintenance, keeping service to a minimum, even with intensive workloads. In addition the hybrid ceramic bearings used for the blower motors ensures a long service life even under heavy loads.

Delivered with an all new robust rolling transport case, the VARIMAT 500 can be transported easily, ergonomically, and safely.

To accommodate individual customer requirements, the VARIMAT is available in two additional versions: VARIMAT 700 and VARIMAT 300.
