|Cutting – Cut PPR pipes to the required length by cutter.|
|Cleaning – Clean the cut end if necessary. Pipe ends must be dry & clean cut at right angles.|
|Marking – Mark the required insertion depth (welding depth) on the pipe with the help of suitable marker.|
Heating – Ensure that the indicator light on the welding device signals that the device is hot enough (260 °C) for welding. First weld can be made after 5 minutes when heating light gets off. Heat the pipe and fitting on the polyfusion device as per the recommended heating times. (The heating times starts, when pipe and fitting have been pushed to the correct welding depth on the matrices.) While heating the pipe and fitting in the matrices, apply slight pressure from both sides.
Welding – After specified heating & holding time, remove the pipe and fitting out of the matrices. Heated end of pipe should be pushed in to the flared end of hot fitting down to the previously marked depth. Do not turn or twist the pipe or fitting while pushing in to the matrices and pulling out of the matrices.
Cooling – After the specified cooling time, the joint gets a first stiffness, after this phase next joint can be made.
