This is serious equipment for waterproofing and lining projects.

The Model 900 is an automatic hot wedge welder made for joining sheets of geomembrane and other thermoplastic materials.

It's built tough for field work.

It runs on 220V power (also has a 110V option), draws 1800W, and welds at a speed you can adjust from 0.5 to 5 meters per minute.

The temperature is digitally controlled and shown on an LCD screen, so you get precise heat for a consistent weld.

It can handle single-layer material thickness from 1.0mm up to 3.0mm (think HDPE, LDPE, EVA, PVC, etc.).

The weld it creates is two strips, each 14mm wide, with a 16mm air channel in between for testing.

The weld strength is strong - over 85% of the original material's strength.

It weighs about 13kg (roughly 29 lbs), so it's portable enough for job sites.

The drive system has a powerful motor that lets it climb slopes, and the pressure rollers are adjustable to make sure both sides of the weld get even pressure.

The hot wedge heating system is high-efficiency.

Perfect for professionals working on landfills, water reservoirs, tunnels, aquaculture ponds, biogas plants, roofing, or any project where you need a waterproof, chemical-resistant seam.

It's a reliable, industrial-grade machine designed to get the job done right in tough conditions.
