Welding & Installation Guidelines
During the jointing process of PP-R pipes and fittings, a welding machine is required.
Welding machines
Application 1. Make sure the working area is safe before starting the machine. 2. Welding heads should be placed on the welding machine so that the parts do not move or are not turned. 3. Plug the welding machine in a 220 volt standard outlet. 4. Adjust the temperature to 260 °C (500° F). Dacta welding machine contains a fast-indicating surface thermometer. 5. Switch on the power button. Heating takes 1-3 minutes. (Switching two buttons will reduce heating time.) 6. Thermostat light will dim down automatically as the temperature reaches 260 °C (500° F). 7. Insert the pipes and fittings to their respective die heads.
During the jointing process of PP-R pipes and fittings, a welding machine is required. Dacta Therm offers two different ypes of welding machines:
a Welding machine for smaller diameters
Welding Threader
Diameter (mm) 20 25 32 40
b Welding machine for bigger diameters

8. If UV or Stabil pipe is used, completely peel off the exterior layer first. Blunt peeling blades must be replaced by Dacta Therm - approved blades, (see page 58) It will be necessary to make trial peelings to ensure the correct setting of the new blade. Push the end of the pipe into the guide of the peeling tool. Peel off the outer layer up to the stop of the peeling tool. lt is not necessary to mark the welding depth as the stop of the peeling tool indicates the correct welding depth. Before starting the fusion, check to ensure the exterior layer has been completely removed.
The various types of welding machines consist of complete devices including power sources, monitors and controls.
