Electrofusion welders

Electrofusion welders are essentially employed in electrofusing polyethylene (PE) and polypropylene (PP) pipes used in gas and water pipe systems, as well as other utilities. In this method, two pipe ends are joined by way of an extra element: an electrofusion fitting. Electric current is then passed through the resistive heating coil in the fitting, which melts and, thus, homogenously joins the material of the fitting and the pipe.

The welder is fitted with a microprocessor controller, making its operation failproof; it also grants full control over the welding process.

You can operate the welder manually or read barcode, in order to enter all necessary parameters (each fitting has a detailed account):

  • fusion voltage [Volt]
  • welding time [sec]
  • fitting type
  • diameter [mm]
  • cooling time [min]

In the barcode setting, be it scanned or entered manually, the welding time updates automatically according to current ambient temperature. In case of a manual setting, a trained welder must put in an appropriate, updated welding time. In the last 10 second of welding, you will hear an intermittent sound signal; whereas the completion of the process will be indicated with a continuous sound.
During the process, the device controls for breaches in the fitting circuitry. The device emits a modulated sound after 3 seconds upon a breach or a voltage drop under 0.5A.
The welder automatically regulates heating voltage. This ensures that your set value will be maintained exact to the 2.5%, in voltage swings in given brackets.
