MACHINE IS EQUIPPED WITH:
- Bernard Cooler
- TE-90 microprocessor welding control unit for single-phase resistance welders.
The welding control unit is used to control the welder components and in particular, the thyristor adjusting the welding current. The TE-90 working cycle is described through 12 programming parameters.
• Synchronous thyristor drive, phase shift control for welding current adjustment.
• Simplified programming by means of four push-buttons.
• Twin pre-setting for time and current, recallable by two independent controls.
• Slope and pulse functions.
• Single and automatic (repeat) operating mode.
• Secondary current compensation function for the welding of oxidized sheets and rods.
• First phase shift delay adjustment. It enables the machine line current best balance.
• Control of solenoid valve 24 Vdc 7.2 W Max with protected output against short circuits.
• "Watch-dog" safety circuit stopping the welder in case of control unit faulty operation, micro-interruptions or too high voltage drop.
