Plastic welding equipment LUND 78911, 800 W, handheld unit, 940 g

LUND 78911 is a handheld plastic welding unit with an 800 W heater and a net weight of 940 g. The tool is supplied as a single unit and is engineered for joining thermoplastic materials, repairing plastic parts and performing small fabrication tasks that require controlled heat. Designed for workshop and DIY use, the device provides a compact solution for working with pipe adapters and plastic fasteners where localised, repeatable heating is required.

Advantages

The LUND 78911 offers a balance of power and portability, delivering an 800 W output in a lightweight handheld format that simplifies maneuvering around joints and fittings. Surface temperature of pipe adapters can reach up to 300 °C, enabling effective softening of common thermoplastics for secure fusion. Built to operate within typical indoor ambient conditions, the unit features electrical insulation class I and an IPX4 protection rating for basic splash resistance. A two-year warranty provides manufacturer-backed coverage for normal use.

How to use

Fit the appropriate pipe adapter or nozzle before switching on the unit, following any adapter-mounting instructions supplied with the product. Connect the tool to a suitable mains supply and allow it to reach operating temperature; monitor the adapter surface temperature up to the specified maximum. Position the heated adapter between the thermoplastic parts to be joined, apply steady pressure and allow the materials to fuse as they soften. For repairs, heat the targeted area evenly and work with compatible filler materials or welding rods if required. After use, switch off and unplug the device, allow it to cool completely before storing or changing accessories.

Usage recommendations

Use the LUND 78911 in well-ventilated areas and follow all safety guidance for working with hot tools and thermoplastics. Select adapter sizes appropriate to the pipe or fitting, avoid exceeding the maximum surface temperature for materials being welded, and wear heat-resistant gloves and eye protection. Ensure the mains supply matches the unit's requirements and inspect the device for damage before each use. Store the tool dry and out of reach of children when cooled.
