لحام إسفين ساخن WELDY WGW 300

The listed ranges are HDPE from 0.8-2.5 mm and LDPE, TPO, FPO, or PVC from 0.8-3.0 mm; it can also weld specified geotextiles. PVC requires a steel wedge. Confirm the machine configuration for the exact material.

Yes. The machine provides direct temperature control up to 450 C and travel-speed adjustment from 0.0-8.5 m/min. Establish production settings with trial welds under actual site conditions.

It produces a double-track seam listed as 2 x 12 mm with a maximum overlap of 150 mm. The channel between the tracks supports air-pressure testing when required by the project procedure.

Its large rollers and durable drive system are designed to support stable travel on typical lining subgrades. The working surface must still be properly prepared and free of sharp objects, excessive steps, standing water, and debris.

PVC requires the specified steel hot wedge. Wedge material for HDPE, LDPE, TPO, FPO, or geotextile should be confirmed for the supplied machine configuration.

Confirm the 230 V supply, wedge type, membrane material and thickness, overlap, roller pressure, temperature, and speed. Clean the seam area, make trial welds, and test completed seams according to the project quality plan.
