A manually operated butt-welding machine suitable for non-pressure PE and PP pipes and fittings from 40 to 160mm OD. Efficient design and construction provides an excellent low cost machine for welding both on the worksite and in the factory. The use of high quality Aluminium castings allows for lower weight without compromising strength and performance. Optional torque wrench allows approximate welding force to be read. PolyBasic machines should not be used for pressure-critical applications or where certification of accurate welding pressure is required.
