WELDY Miniwelder Geo2

The listed ranges are LDPE and PVC from 0.5-1.5 mm, TPO and FPO from 0.7-1.5 mm, and HDPE from 0.4-1.0 mm. PVC requires the specified steel wedge. Confirm the current configuration for the exact membrane.

Yes. Temperature is adjustable from 60-450 C and travel speed from 0.4-7.5 m/min. Settings must be established with trial welds for the membrane type, thickness, ambient temperature, and site conditions.

It produces a double-track seam listed as 2 x 12 mm, with a maximum overlap of 100 mm. The channel between the tracks supports air-pressure testing when the project procedure requires it.

PVC must be welded with the specified steel wedge. Copper or chrome-steel wedge selection for other materials should follow the machine configuration and membrane supplier guidance.

Its 3.9 kg lightweight design is suited to thin thermoplastic membranes, smaller lining work, confined areas, and projects where portability and controlled overlap welding are important.

Confirm voltage, wedge material, membrane type and thickness, overlap, roller pressure, temperature, and speed. Clean the seam area, make trial welds, and test the finished seam according to the project quality plan.

Yes. WELDY is an official sub-brand of the Swiss LEISTER Group, adopting Swiss professional plastic welding technology, global unified quality standards and technical specifications. It is a cost-effective industrial welding equipment brand under Leister.

No. WELDY equipment is not Swiss original imported. It is developed by Swiss LEISTER Group and manufactured in Shanghai, China by Leister’s local factory, strictly following Swiss technical standards and production processes.

Both belong to the Swiss LEISTER Group. LEISTER is the high-end Swiss original imported series for ultra-high standard industrial projects; WELDY is the cost-effective sub-brand with Swiss technology, manufactured in Shanghai, suitable for most civil engineering, environmental protection and geomembrane welding projects with stable performance and lower cost.

Absolutely reliable. As a Leister sub-brand, WELDY inherits Swiss welding technology and quality control system. All machines are professionally calibrated for HDPE, LLDPE and PVC geomembrane welding, widely used in global landfill, mining, aquaculture and biogas projects.

We provide full-series WELDY geomembrane welding equipment, including automatic hot wedge welders, handheld extrusion welders and industrial hot air guns. All devices are dedicated to plastic and geomembrane anti-seepage construction.
