Control Unit TECNA TE 90 Mark II

TECNA TE 90 Mark II Control Unit

Features:

The TECNA (TE90) MARK II control unit is designed for managing single-phase spot welders, both manually driven and pneumatically operated. It is a microprocessor control system that precisely regulates the fundamental parameters of the resistance welding process, ensuring reliable and constant work cycles.

The (TE90) enables direct control of the welding machine components, with particular emphasis on current regulation through controlled diodes. The duty cycle is executed following programmable logic based on predefined parameters. It is also possible to recall two distinct time and current configurations via independent commands.

• Synchronous control with controlled diodes, current regulation by phase control
• Simplified programming with four keys
• Double time and current configuration, activatable through two independent commands
• Ramp (slope) function and pulses
• Selection between single-cycle and automatic
• Secondary current compensation function, useful for welding pieces with oxide (plates, rods)
• Possibility to deactivate auto-pickup for use with manual welders
• Adjustment of the initial insertion delay to optimize network consumption
• 24V DC solenoid valve management / 7.2W max. with short-circuit protected output
