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.
