Main Features:

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

- Working cycle specially designed for Roll welding machines.

- Three different hot cycles in each program, that can be recalled during program running.

- Initial current slope up and final current slope down independently adjustable.

- 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 selected from internal or external.

- 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.

- Setting of the first insertion delay with a system parameter.

- Separate proportional valve outlet galvanic insulated.

- Setting of the proportional valve full opening range (100%) form 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 recognition.

- Dedicated signals for PLC drive.
