Pipe Welding

Preparing the Welding Machine

· Fit the welding Machine with the dies of required pipe fitting diameter to be    processed and connect the plug to the 230 V power supply socket Wait until the thermostat light on the machine goes off, indicating that the welding machine has reached the working temperature (260˚C).

· Cut the pipe at right angles to axis. In order to avoid the errors in defining the distances and direction of the fittings, one may use a pencil for marking.

· Push the end of the pipe and simultaneously the fitting without turning them up to the marked welding depth into the tools (Fig 2). It is important to observe the heating times of the assembly parts.

· After the stipulated heating time, quickly remove pipe & fitting from the welding dies. them immediately and without turning, until the marked welding depth of pipe is covered by PP-R fitting.(Fig.3)

· After heating the joining parts don’t push them vigorously. At the stage of joining, it is possible to effect the rotation of maximum 10˚ to 15˚ in order to perform coaxial correction.
