High and low-force welding. Worldpoly45o High Force is a hydraulically operated butt-welding machine suitable for PE and PP pipes and fittings from zoo to 45omm 00. using both high and low force welding methods. Excellent Australian Engineered design and construction provides a premium machine for welding both on the worksite and in the factory. The use of high quality pressure-cast Aluminium clamps allows for lower weight without compromising strength and performance. while providing extra strength when welding out-of-round pipe. Significantly increased force is available for drag when welding pipe strings. or on difficult sites. Welding can be carried out between clamps 3 & 4 for tees. bends and manifold work. and the machine is pre-wired for immediate integration with optional data Logger. and overhead electric crane.
