Leister Unveils the VARIMAT 700: a New Era in Roof Sealing Technology

Innovative features and design for optimum performance

The VARIMAT 700 is characterized by its robust construction and ergonomic design. The automatic 
roof welding machine comes in a sturdy rolling transport case, ensuring convenient and safe 
transportation to the place of use. With a dead weight of 37 kg and optional additional weights, the 
VARIMAT 700 offers high joining pressure for constant process safety when welding thermoplastic 
sealing sheets and all types of membranes.

A balanced triangular design takes care of directional stability, while the flexible transport axis 
facilitates welding close to the edge. The choice of 230 V or 400 V offers users additional flexibility.

Roland Beeler, Head of Business Line Roofing at Leister, explains: “The VARIMAT 700 is a milestone 
in the development of welding devices for roofers. With its unique combination of performance, 
user-friendliness and digital connectivity, we are setting new standards in the industry.”

Wide range of applications

In addition to use on roofs, the VARIMAT 700 can also be used for swimming pool construction as 
well as welding truck tarpaulins and advertising banners. This versatility underlines Leister’s 
innovative strength.

Leister Quality System LQS Roofing for quality assurance

Equipped with the proven Leister Quality System LQS-Roofing, the VARIMAT 700 enables the 
creation of digital quality documentation for the completed welds. This documentation can then be
