Welding Machines

Leister develops and manufactures automatic welders and welding machines that are used to weld thermoplastic membranes on roofs, landfills, tunnels, truck tarpaulins and shading systems.

Details

Innovative Roof Welding Machine

The new UNIROOF AT is a service-friendly roof welding machine for welding thermoplastic membranes on both flat roofs and slight inclines (up to 30°). Compared to the predecessor, UNIROOF E, the welding parameters can be adjusted intuitively on the display. The slim housing construction and movable transportation axle also eliminate time-consuming machine conversion for different applications. It can easily weld as close as 4” (100mm) to a wall, on top of parapets, on flat surfaces, or in any difficult-to-reach “problem areas on a roof”.

The UNIROOF AT makes it possible to weld all thermoplastic membranes as well as select hybrid EPDM membranes. With specifications of 3450 W, 230 V and a maximum of 15 A, the welding machine can be used anywhere: Thanks to the low 15 A maximum power consumption, users are more independent of the power supply quality, because no high voltage is necessary for the use of the device. The maintenance-free direct drive in the pressure roller is additionally characterized by service-friendly, higher contact pressure and significantly higher welding speed than all corresponding competitor products. The new UNIROOF AT outperforms comparable machinery by 66%. With the flexible accessory assortment for welding rib profiles, welding by hand is no longer necessary. The completely controlled closed-loop system for drive, temperature and blower volume ensures process and investment security for builders and companies alike.

Highlights

Simple, Digital Operation

DIGITAL
Practical Operating Panel
The digital display showing both welding parameters (target/current values for running time) and incoming voltage ensure continuous monitoring.
Save time thanks to programmable welding profiles for the most common roof membranes.

AGILE
Quick Adjustment
The slim automatic roof welding machine with movable transportation axle effortlessly tackles welding as close as 4” (100mm) to a wall,
on top of parapets, on flat surfaces, and in any area where space is very tight.

SOPHISTICATED
Safe, Closed-Loop Welding
The automatic welders closed-loop system fully controls the speed,
temperature and air flow and ensures that they remain constant during the welding process.
This increases dependability and safety.
