Maximum flexibility, absolute precision: the ideal choice for complex PVC joints

The SLTV from Graf Synergy is a single-head welding machine designed to provide maximum versatility for the most technical and complex operations. With its variable angle head, it allows for angle welds ranging from 35° to 180°, including ‘T’, cross, or ‘H’ configurations (notch welding). The fully automated cycle ensures consistency, repeatability, and a reduction in errors, even with pointed cut profiles and V-grooved counterpieces. It is ideal for manufacturers looking to expand their range of fixtures while offering a highly customised service.
