Main Features:

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

- Working cycle specially designed for Spot welding machines.

- Three different hot cycles: preheating, welding, post heating.

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

- Welding 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.

- Start cycle 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%) 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. - Fully adjustable from a PC program.

- Interchangeable with previous versions ( IP3/S 1208 - IP3/S 1250 ).
