Product Description
LST-GM1/GM2 Geo Hot Wedge Welder
Product Introduction
This welding machine adopts an advanced hot wedge structure, which is small in size, light in weight, and powerful. It is suitable for welding various hot film materials of 0.2-2.0mm. There are two models: bidirectional film entry and single-sided film entry. The product is used in waterproofing and seepage prevention projects in tunnels, subways, water conservancy, aquaculture, biogas digesters, landfills, chemical and mining industries, sewage treatment, roof construction and other fields.

Advantages
Control System: Advanced feedback-based intelligent digital control system; temperature and speed are intuitively displayed on an LCD screen, offering high control precision and strong protection functions.
Pressure Regulation System: Advanced T-shaped cantilever head design and pressure regulation mechanism ensure balanced pressure on both sides of the weld bead, resulting in uniform welds. Welding pressure is continuously adjustable.
Pressure Roller Mechanism: Special steel pressure rollers provide strong, non-slip pressure and are durable.
Heating System: High-power alloy wedge and unique heating design result in higher heating efficiency, better welding performance, and a longer service life.
Film Feeding System: Available in bidirectional and single-sided film feeding models to meet customer application needs.
