Soudeur d'extrusion WELDY Booster EX3

The Booster EX3 is specified for compatible HDPE, LDPE, LLDPE, and PP materials. Use welding rod that is compatible with the parent material and complete a trial weld before production work.

It accepts 3 mm and 4 mm welding rod. Confirm the rod material, diameter, welding shoe, and joint geometry for the application before ordering.

The listed maximum output is 3.4 kg/h. Actual output varies with material, rod diameter, temperature settings, operator technique, and site conditions.

Its higher-output barrel extruder is used for geomembrane details, plastic fabrication, corners, penetrations, patches, seam finishing, and repair work in HDPE, LDPE, LLDPE, and PP.

Yes, it can extrusion-weld compatible patches and repair details when the damaged area is prepared correctly and the rod matches the membrane. Repair geometry and testing should follow the project quality plan.

The EX3 has a listed maximum output of 3.4 kg/h and a weight of 6.9 kg, while the EX2 is listed at 2.5 kg/h and 6.4 kg. Select according to required output, handling preference, joint geometry, and site workload.

Confirm the 230 V power supply, destination plug, weldable material, 3 or 4 mm rod, required welding-shoe geometry, and spare or wearing parts needed for the job.

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.

1. WELDY Hot Wedge Welder: Automatic double-track welding, high efficiency, for large-area flat geomembrane main seams (landfill, reservoir, tailings pond). 2. WELDY Extrusion Welder: Rod melting filling welding, high weld strength, suitable for corners, slopes, irregular joints and membrane repair. 3. WELDY Hot Air Gun: Portable handheld tool for edge trimming, auxiliary welding and small-area repair works.

Adopting Swiss standard melting and extrusion technology, the weld seam features high tensile strength and strong anti-leakage performance. It can weld thick geomembrane from 0.3mm to 3.0mm, and solve difficult welding problems such as slopes, corners and membrane damage repair.

Yes. We are an authorized exporter of WELDY brand under Swiss LEISTER Group, supplying genuine Shanghai-manufactured WELDY welding machines, original spare parts and supporting welding rods.

We provide 1-year official warranty for all WELDY machines. Wearing parts such as heating elements and nozzles are supplied at factory cost. We support global shipping and professional English technical guidance.

Yes. We provide complete English user manuals, operation video tutorials and online technical support for overseas geomembrane welding projects.
