The BAK ProtOn WEDGE is a compact automatic hot-wedge welding machine developed for professional thermoplastic geomembrane welding in civil engineering, tunnels, reservoirs, ponds, canals, landfill projects, waterproofing and other GEO applications.
It is primarily designed for HDPE and LDPE geomembranes, while BAK also lists PP, ECB, EVA and TPO within its welding material range. The copper wedge transfers heat directly into the overlap, while temperature, speed and welding pressure can be adjusted continuously to match the material and job-site conditions.
Compact and easy to handle
At approximately 9.5 kg and 370 x 435 x 280 mm, the ProtOn WEDGE is designed for practical transportation and controlled operation on site. Its compact geometry also makes radius welding possible, which is useful where the membrane path is not completely straight.

Applications
ProtOn WEDGE is intended for geomembranes and technical foils used in ponds, reservoirs, canals, landfill engineering, civil construction, waterproofing, tunnels and other projects requiring repeatable thermoplastic membrane seams.
For buyers comparing Leister TWINNY or GEOSTAR solutions
Customers searching for a geomembrane welding machine, HDPE welder, hot wedge welder or Leister TWINNY / GEOSTAR alternative can evaluate the ProtOn WEDGE according to membrane material, thickness, required speed, welding pressure, seam geometry and site conditions. It should be treated as a distinct BAK solution with its own hot-wedge design and technical parameters, not as an identical replacement for a Leister model.
