Geomembrane Welding Equipment
Automatic Welders
GEOSTAR G5/G7 Wedge Welder
The GEOSTAR wedge welder is the fastest Leister wedge welder available with a top welding speed of 12 m/min, depending on conditions. |
COMET 700 Wedge Welder
The COMET 700 automatic hot-wedge welder from Leister offers everything that civil engineering users want when overlap welding thick and thin geomembranes made of PE, HDPE and LDPE. |
COMET 500 Wedge Welder
The COMET 500 hot-wedge welding machine from Leister offers practical convenience to reliably weld thick and thin geomembranes made of thermoplastics such as PE, HDPE and LDPE. |
TWINNY T7 Hot Air Welder
Ideal for welding geomembranes from 20-100 mils (0.5-2.5 mm), the TWINNY T5 welds almost 50% faster than its predecessor, TWINNY T, while the TWINNY T7 is twice as fast |

WELDPLAST S2 Extrusion Welder
Ergonomically designed, the WELDPLAST S2 features a revolutionary brushless, maintenance-free motor for generating preheated air. |
WELDPLAST S4 Extrusion Welder
Compact and ergonomically designed, the WELDPLAST S4 features a revolutionary brushless, maintenance free motor for generating preheated air. |
WELDPLAST 605 Extrusion Welder
The WELDPLAST 605 is the successor to the WELDPLAST S6. Specially designed for PE, the WELDPLAST 605 is ideally suited for civil engineering projects. |
FUSION 3 Extrusion Welder
Easy operation due to its ergonomic, slim line design. With a designed length of 670 mm, the FUSION 3 is ideally suited to use in geomembrane welding. |
FUSION 3C Extrusion Welder
Easy operation due to its compact design. With a designed length of 580 mm, the FUSION 3C is ideally suited to use for high output use in plastic fabrication. |
Hot Air Hand Tools
TRIAC ST Hot Air Hand Tool
The new TRIAC ST from Leister is the seventh generation of the revolutionary TRIAC family of tools. Easy to use, output is controlled via a rotary knob just like the TRIAC S. |
TRIAC AT Hot Air Hand Tool
The TRIAC AT offers the advantages of closed-loop temperature control, independent air flow control, and a digital display. |
ELECTRON ST Hot Air Hand Tool
The ELECTRON ST is a real powerhouse among Leister's hand tools; it provides high heating efficiency and large air volume in a compact size. |
UNIDRIVE Semi-Automatic Welder
The UNIDRIVE 500 welds every overlap, even if space is tight, three times faster than manual welding. |
Weld Testing Equipment
EXAMO Tensiometer
Ideal for tensile measurements directly at the construction site. Optional data recording to a memory card. Clamp separation width 600 mm. |
Manual Testing Equipment
The vacuum box and pump (shown above) and other manual testing devices from Leister are convenient ways to perform weld tests in the field. |
