VARIMAT 700

The Leister VARIMAT 700 roof welding machine welds TPO roof membranes with myLeister LQS roofing, GPS welding protocol and high welding speed.

VARIMAT 500

The Leister VARIMAT 500 roof welding machine can be converted from 230 V to 400 V and welds TPO plastic sealing membranes reliably and ergonomically.

VARIMAT 300

The ergonomic Leister VARIMAT 300 roof welding machine offers everything needed for welding roof membranes.

Process reliable flat roof welding
The VARIMAT 500 automatic welding machine from Leister ensures reliable process safety when welding plastic sealing membranes and bitumen membranes on flat roofs. With high contact pressure, easy conversion from 230 to 400 V and innovative swing-in mechanism, it offers fast and precise nozzle positioning into the overlap. The flexible transport axis of the VARIMAT 500 ensures accurate tracking, even in roof closures close to the edge.
Like its "big brother", the VARIMAT 700 automatic welder, the VARIMAT 500 is designed for many different applications: Whether for roofing work or swimming pool construction, the waterproofing membranes are processed reliably and quickly. Truck tarpaulins and advertising banners can also be welded perfectly with the VARIMAT 500. Its air partitioning concept, which is decoupled from the pressure roller, prevents wrinkles during welding. This ensures both optimal water flow and attractive appearance. The Monitored Welding Assistant gives users the assurance that the weld meets the high quality requirements of the customer. If the set welding parameters (temperature, speed and air volume) are exceeded, the VARIMAT 500 signals this with an acoustic and optical signal. In the event of undervoltage up to a maximum of 20 %, the automatic roof welding machine continues to reach the required welding temperature thanks to its power management. If the undervoltage is greater than 20 %, the VARIMAT 500 switches off automatically because the quality of the weld may then no longer be guaranteed. To ensure that the correct welding parameters are set, Leister offers reliable welding profiles and a "library" of proven welding recipes in the myLeister app. At the customer’s request, the VARIMAT 500 was equipped with an LED work light. Thus, welding of the roofing membranes is possible even at night or at dusk, because the welding zone is optimally illuminated. The large, user-friendly display and its rotating adjustment knob make the VARIMAT 500 intuitive to operate. Service requirements are low due to the brushless, maintenance-free hot air blower, even under intensive load. Hybrid ceramic bearings in the blower motors ensure a long service life. The VARIMAT 500 can be transported easily, ergonomically and safely in the sturdy rolling transport case (included in delivery). In order to cover individual customer requirements, the VARIMAT is available in two further versions: VARIMAT 700 and VARIMAT 300.

Flat roof welding made easy

Removable weights
To achieve a high contact pressure, the VARIMAT 300 has a base weight of 14 kg and an additional weight of 3 kg. Both weights can be removed for easy transport.

Good weight distribution
The VARIMAT 300 from Leister stays precisely on course when sealing flat roofs thanks to its triangular design and variable transport axis.

Practical rolling transport case
In the practical rolling transport case with telescopic handle, the VARIMAT 300 from Leister is always safely packed and ergonomically transportable.
