Main Features:

- Synchronous control for SCR with phase cut off weld current regulation.

- Working cycle specially designed for Spot weld machines.

- Three different hot cycles: preheat, weld, after heat.

- Weld time setting up to 10 with a resolution of ½ period; above 10 with a resolution of 1 period.

- Weld current setting in thousands of half wave phase cut off.

- All outlets and inlets are galvanic insulated. - Setting and running capability of 32 programs remote or locally selected.

- Copy function to overwrite automatically the program 0 on all other programs.

- Line voltage compensation with activation / deactivation by system parameter.

- Network serial interface RS485. - Cycle start with concomitance (dual inlet) or via foot switch.

- First insertion delay setting with a system parameter.

- Separate proportional valve outlet galvanic insulated.

- Setting of the proportional valve full range (100%) from 5 to 10 volt with a system parameter.

- Three different Cycle Ends with correspondent time setting by system parameters.

- 16 current tables for different machine’s power factor.

- Pre stroke solenoid valve acting as pre stroke with manual opening or opening at cycle end selectable with a system parameter.

- Automatic power line frequency recogntion.

- Dedicated signals for PLC drive.
