Operation 

4.1

 

General Information on the Applied Procedure 

Electrofusion welding is characterized by thermal fusion of the outer 
surface of the pipe and the inner surface of the weld fitting by heating 
the heater coil incorporated into the fitting. In this process, the weld 
fitting shrinks and thereby creates the contact pressure needed to carry 
out the fusion of pipe and fitting surfaces. The automatic welding unit 
provides the electrical energy needed to perform this and control the 
energy supply according to certain parameters, such as ambient tempera-
ture. 

4.2

 

Preparing the Welding Process 

In all cases, the relevant information supplied by the manufacturer of the 
pipes and the fittings have to be respected. First, both pipe butt have to 
be cut at right angles and level using appropriate tools. Then, using a 
chamfering and peeling tool or a handheld scraper, chamfer the edge and 
smoothen the pipe surface up to the length it will be inserted into the 
fitting. Then, the weld surface that is achieved by this process has to be 
de-fatted using an appropriate solvent (non-fibrous paper, spirit or suit-
able alcohol). Make sure nobody touches the cleansed surface and secure 
pipe and fitting for the welding operation. 

4.3

 

Turning the Welding Unit On 

After connecting the power supply cord to 230V mains power, turn the 
welding unit on using the main switch. The unit then performs an auto-
test. All three LEDs are on briefly simultaneously to indicate that the unit 
is ready for operation. Furthermore, the seven-segment characters show 
the welding mode H0 for approximately 1 second. After this, both the 
LEDs and the screen characters change back to off. 

4.4

 

Connecting the Electro fusion Fitting 

Connect the connection terminals to the fitting and check for proper 
contact. The contact surfaces of the connection terminals and the fitting 
have to be clean. Dirty contacts may lead to improper welding and also to 
overheated and fused connection terminals. 

After the fitting was connected, the yellow LED (Fitting connected) is on. 
At the same time, the screen displays the welding time. By pressing the 
START key, the welding process can now be started. 

The welding time is counted down from about 80 s. To determine the 
welding duration that will be needed, the ambient temperature is taken 
into consideration to some extent, which may result in a welding time 
slightly longer or shorter than 80 s.
