Previous | Next

The Hot Spot Welding mini is a complete system enclosed in one unit (430 x 420 x 150 mm) for resistor welding applications. It is composed of:

> Primary inverter
> High frequency transformer
> Power diodes
> Shunt
> Control Processing Unit with RS232 serial line
> Operator control panel with 1 line by 16 characters display
> Main switch

Controlled via RS232 serial line by a PC/PLC or CRS remote control unit (Part Number: REM305 or REM306).
