In biogas digesters, circular aquaculture ponds and small landfill projects, geomembrane weld quality defines long-term anti-seepage performance. Curved surfaces and uneven ground make consistent welding a real on-site challenge.

Weighing only 7 kg with 1400 W power, the CX300 is a dual-purpose welder built for portability without sacrificing performance. Its compact frame is easy to carry and reposition around circular pond perimeters and confined work areas.

The machine features digital closed-loop control for precise temperature (0–450°C) and speed (0–8 m/min) adjustment, helping operators avoid cold welds and burn-through. Settings are displayed on an LCD screen for easy monitoring and documentation.

Its aviation-aluminum main frame and CNC-machined precision bearings—Japanese IKO needle rollers paired with German NSK deep groove balls—ensure stable travel and uniform pressure across both weld tracks during continuous operation.

At the core, a high-conductivity copper hot wedge and curved heating cartridge ensure efficient, uniform heat transfer for consistent seam fusion. The CX300 produces standard 15 mm dual-track seams with a 12 mm air-testing channel for on-site pressure inspection, compatible with 0.5–1.5 mm geomembrane.

Supporting both same-side and dual-side film entry, the CX300 delivers weld tensile strength of at least 85% of the base material and adapts to circular and standard project layouts alike—a practical, portable solution for real-world containment construction.
