Bench welding mirrors POLYS P-4
Bench welding mirrors are a special variation of the popular hand welders POLYS P-4. The welding mirrors have a round heating plate, covered at both sides with a layer of a special antiadhesive thermoplastic material (PTFE). This type of heating plate is mainly used for welding of thin wall plastic pipes, especially in construction of drain systems or similar distribution systems for substances where high pressure tolerance is not required.

The design of the welding mirror enables its fixation to the working table using a clamp. This enables the welder to have both hands free to complete the welding process. The temperature is controlled by the reliable systems used in the hand welders POLYS P-4.

TraceWeld is the most modern control system of fusion welding and it is available in all
the POLYS P-4 welders. Each type of this welder has a slightly different control means.
As an example we would demonstrate the P-4a, since this type of control is the most popular one. The set of welding temperature and of the pipe size is very simple just by turning the control wheel and the rest is done by the electronics. The patented TraceWeld system allows even less experienced operators to make perfect welds.

The P4a welder allows for the precise setting of the temperature from 180 to 280 degrees C. The temperature setting is executed by the blue setting wheel 1. The operator must use a tool such as a screw driver or a small coin to be able to adjust the welding temperature setting.
The outer red ring 2 is used to set the pipe size. After the temperature and the pipe size were set, the welder is turned on by plugging it
to the power outlet. The correct operation of the welder is indicated by
the lit red diode 3 and also by the green LED 4 for the temperature. When the green diode starts flashing , the welder is ready to start
the welding process. Just before pressing the pipe ends to the welder attachments, the operator shall push the button Timer 5. The welding process is indicated as follows:

The professional Blue Line of welders is available with four types of temperature control. They can be also ordered with top of the line acoustic and visual signalling TraceWeld .
The above system provides the welding process times according to the material type and the pipe size.

The P-4a welder has the infinitely variable temperature settings from 180 to 280 °C. The temperature set point is achieved by turning the control button.
The P-4a welder with acoustic signalling TraceWeld provides the welding process times. The temperature settings is made by the inner part of the control button, while the process signalling times are given by entering the pipe size by the outer part of said button with click in positions for each pipe size settings.

The P-4b welder lets you set the welding temperature with a thumb switch with steps of 5 °C. The minimum set temperature is 100 °C. That would allow welding of materials with very low melting point.

The P-4c allows to set infinitely variable welding temperature and
acoustic signalling by the three push buttons. The temperature is shown on the display. The TraceWeld system is controlled by one multifunction push button, where the long push would set the pipe size and the short push would start the welding cycle timing.
