WELDING INSTRUCTIONS

The quality and the life span of any pipe installation depends equally on both the geometric accuracy and the welding’s. Connecting pipes and fittings through melting takes just a few seconds. After a few minutes the welded pipe installation is ready to be installed. You cut the pipe, heat the fitting with the welding machine and then connect the two parts. That's all Fast, without substantial efforts and with wonderful result. All welded connections are completely safe because when the polypropylene cools down there's no change in its structure, shape or durability.

INSTRUCTIONS FOR WELDING PIPES AND FITINGS

  • 1. Choose the approprite detail and put it on the welding machine.
  • 2. Turn on the welding machine. Wait until the two control indicators are heating. When the device is ready for use the indicator turns off. This means that the necessary temperature has been reached /260° C +,- 10°C /
  • 3. Attach properly the end of the pipe and the fitting to the welding device.
  • 4. If the pipe or the fiting is dirty clean it with water and alcohol soluiton.
  • 5. Then heat equally for the duration of few seconds both the pipe and the fiting. Then connect them and leave them for a few minutes to cool down so that the welding be successful.
  • The necessary heating time, welding time and cool-down time for each corresponding pipe diameter is shown in the following table.

Can be used in drinking water systems and has a quality certificate issued by The Ministry of Health and Hygiene-Institute. It makes it possible to load more on transportation vehicles and to lower the cost value.
