Foil welding with regulators or TSR

During film welding, impulse welding or PE film welding, there is a high inrush current which causes the fuse to blow and the machine to fail. In order to completely avoid this problem, a transformer inrush switch is used. This ensures that no failure can occur due to the inrush. It also enables the appliance to be switched quickly and safely.

Calculation tables for transformer design

Applications: Temperature controller, TPRA, TPRB, TPRC, PIREG

This application is suitable for impulse welding of plastic films that are heated via metal strips. The metal strips are fed from the transformer secondary side and brought to the set temperature within 0.1 - 0.8 seconds.

 

The temperature controller-TPRC... regulates the temperature of the metal strips on the primary side of the transformer to the nearest degree C. The voltage and current are measured by the controller directly at the metal sealing strip and the temperature is calculated from this because the controller knows the Tk.

Temperature control with the TSRLF transformer switch

A TSRLF module together with a mom.schalt. solid state relay, a TSRLF module can gently switch on a transformer for plastic film welding on the primary side and clock it with pulse groups according to an external control signal.

Temperature control with the TSRL transformer switch

Control the temperature by switching the transformer on and off with the TSRL. The simplest solution.

The TSRL is the best solution for welds that do not require tightness, such as welding a new roller to the web of the old roller. The transformer can be optimized and costs can be saved.

Temperature control with 106 or ZPGS time pulse group control

Control boards for film welding with table-top devices

 

Temperature control by fast pulse group timing of the welding transformer, with adjustable pulse-pause patterns. Particularly suitable for table-top welding machines.
