A40 – automatic roof welder 40 mm, 3,600 W

Self-propelled hot-air welder for overlaps of PVC and TPO roofing membranes on flat roofs. Built for large areas – industrial halls, warehouses, retail buildings – where an even, repeatable seam and crew productivity matter.

Temperature and travel speed are set digitally; a controller with an outlet temperature sensor keeps the parameters stable along the whole seam.

Key features

• Digital temperature and speed control – settings matched to membrane thickness and weather
• PID control with temperature sensor – stable air temperature at the nozzle outlet
• 40 mm nozzle – standard seam width for roofing membrane overlaps
• Externally mounted motor – better cooling and longer life in continuous work
• Service and spare parts in Poland – heating elements, brushes and nozzles shipped from Poland

Applications

Welding overlaps of 0.8–2.0 mm PVC and TPO membranes on flat roofs. For seam checks we recommend the AVK-SZ seam probe.

AVELKOR is a brand of hot-air welders and tools for PVC, TPO and FPO roofing membranes. We sell, rent and service the equipment and ship heating elements, carbon brushes, nozzles and rollers from Poland.
