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. Thanks to the proven Leister Quality System (LQS), the COMET 700 documents the welding parameters and GPS coordinates of all welds. The easy-to-read data report highlights potential errors, allowing you to check and fix them quickly. The COMET 700 sets a benchmark for overlap welds up to 125 mm, thanks to its electronic equipment and its particularly high heating power.

  • Two wedge lengths available: 60 mm and 90 mm
  • Powerful drive motor handles uneven and steep terrain
  • Digital display shows speed, temperature, welding pressure, and voltage
  • Acoustic alarm when welding pressure deviates from defined range
