The BAK ComOn3 is a professional hot wedge welding machine for geomembranes, liners and thermoplastic membranes used in waterproofing, civil engineering, tunnels, landfills, ponds, tanks and industrial sealing applications. It is designed for demanding job sites where consistent speed, controlled pressure and repeatable weld quality are essential.
The ComOn3 operates on 230V and uses a powerful maintenance-free servo motor. Its digital display allows the operator to monitor temperature, speed and pressure, while the plug-in wedge design makes wedge changes easier when adapting the machine to different applications.
BAK specifies the ComOn3 for PE-LD, PE-HD, PP, ECB, EVA and TPO materials. For HDPE, the specified welding range is approximately 1.0-3.0 mm. The machine offers switchable speeds of 5 or 10 m/min, welding pressure up to 1500 N and wedge lengths of 100 or 80 mm depending on configuration.

The ComOn3 is suitable for professional geomembrane welding in ponds, tanks, landfill systems, tunnels, civil engineering, containment barriers and other thermoplastic liner applications.
Buyers comparing Leister geomembrane welders such as COMET 500, COMET 700, GEOSTAR or TWINNY can evaluate the BAK ComOn3 as a professional alternative based on material, liner thickness, speed, welding pressure, wedge configuration and documentation requirements. Selection should be based on the application rather than brand name alone.
RezistenteMag supports BAK / HERZ equipment with stock and supply capability, accessories, auxiliary units, spare parts, consumables, technical assistance and service. For configuration support, provide the membrane material, thickness, required seam geometry, job-site conditions and whether welding data recording is required.
