Spider Socket Welding Machine - With Universal Clamping

The Spider™ 125 with Universal Clamping system is the preferred equipment for quick and accurate socket fusion field installations of 63mm to 125mm polypropylene pipe.

The lightweight, compact device features a worm gear drive with parallel link system to bring pipe and fittings together evenly and under control. It features a Universal Clamping system that can accommodate any size of pipe or coupling, eliminating the need for inserts.

The features of the Spider 125 allow a single technician to properly align, heat, fuse and cool the pipe. Because the Spider is non back-drivable, constant pressure is maintained throughout the process.

The Spider has proven to be an exceptional tool for performing socket fusions in overhead, vertical and tight work spaces. A full assortment of heaters and heater adapters are available from Asahi/America for pipe sizes in the 63mm to 125mm range.
