PPR hot melt is used as follows:

1. Install the heating end of the fixed welding device, place the welding device on the shelf, install the corresponding heating die according to the required pipe specifications, and tighten it with the hex socket, generally small in the front end and large in the back end.
2. Switch on the power supply (note that the power supply must have a grounding protection wire), and pay attention to the change of the indicator light according to the instruction manual of the corresponding model of the machine, until the welding device enters the working temperature control state, you can start to operate.
3. Cut the pipe vertically with the pipe cutter, push the pipe and pipe fittings into the die head of the welding machine without rotation at the same time, and operate as required. After reaching the heating time, immediately remove the pipe and pipe fittings from the die head at the same time, and quickly insert them into the required depth in a straight and uniform way without rotation, so that a uniform flange is formed at the joint.
