Overlap Welder Combined Hot Wedge Hot Air model Proton

DescriptionThe smallest, light weight automatic welding machine to well a range of thermoplastic geomembranes. The Proton is a combined “Wedge” and “Hot Air” welder, with a brushless motor/heater unit. For Civil engineering and tunnel (overhead) welding applications.Voltage 230 voltWattage 2200 wattTemperature range up to 550 Deg CWelding Speed max. 5m/minuteMaterial welding range: PE-LD, PE-HD, PVC-P, PP, ECB, EVA, TPODimensions 370mm x 340mm x 330mmSeam dimensions 15mm – 15mm – 15mm (centre channel unwelded)Weight 9.8 kg’sCE conformityMade in SwitzerlandDocumentsBrochure Techspan Proton Wedge/Hot Air WelderVideo – Proton Wedge/Hot Air welderCommon applications for the Proton overlap welderTruck tarp manufacturing – long PVC fabric seamsCommercial flat roof field seam welding on TPO, PVC and reinforced membranesBanner and large-format signage productionPool cover and pond liner manufacturingGeomembrane installation – large area field weldsWhy combined hot wedge hot airThe Proton welds both hot wedge (interior contact heating) and hot air in one machine, switchable for the substrate. Hot wedge is faster and produces a uniform bead – ideal for production PVC fabric and roofing membrane. Hot air mode handles materials and thicknesses where wedge contact would mark or damage the surface.What pairs with the ProtonPVC rod for detail and patch work that the automatic doesn’t handleHand welder for tabs, corners and patches around the automatic seamsVacuum or air-pressure test kit for QA on completed seamsFAQs What’s the production speed?Production speed depends on substrate, but automatic overlap welders typically run 3-5x faster than hand welding. For long straight seams on PVC tarp or membrane, the productivity gain is substantial. Does it weld both PVC and TPO?Yes. The Proton handles PVC fabric, TPO roofing, reinforced membrane and most flexible welded plastics. Set temperature, speed and pressure to suit the substrate. When should I choose a wedge-only or air-only welder?Wedge-only welders are faster and cheaper if you only weld one substrate type (production tarp shop). Air-only welders suit roofing field crews who need flexibility on different membranes. The combined Proton suits operators who do both.
