5.2 Welding process

Basically, the valid welding regulations (ISO/CEN/DVS...) are to be observed. Do wear safety

gloves as protection against burning !

• A stop-watch is to be available in order to be able to register the actual times for heating up

and cooling.

• A welding table is to be available from which you can read the parameters that are prescribed

by the welding regulations for the pipe dimension to be welded.

• The heating element socket / spigot are to be clean and, above all, free from grease.

• Therefore they are to be cleaned with non-fraying paper and detergent (e.g. PE-cleaner) before

every welding or if they are dirty.

The nonstick coating of the heating element must remain undamaged in the working area.

• In addition, the workpieces (tting and pipe) to be welded must be clean. If need be, clean

them with detergent and non-fraying paper.

• The pipe end is to be chamfered to appr. 15°.

• Switch on the heating element and adjust the necessary welding temperature at the adjusting

screw at the handle.

• If the control lamp blinks, the nominal temperature has been reached and is maintained by a

deﬁned pulse-position ratio.

• Take the values for heating time, change over time and cooling time from the table.

• Press the tting in the right-hand clamping device onto the stop and clamp it tightly.
