- Synchronous welding control with silicon controlled rectifiers for the regulation of the weld current by mean of phase cut off procedure. Response speed: 2 cycles for the first weld and then ½ cycle for every successive weld.

   - Three different control modes:

• Voltage percentage V%
• Current percentage I% (set in feed - forward)
• Constant current IK (1,0 – 99,0 KA)

   - Suitable for machines with single phase welding transformer.

   - Management of Spot-weld cycles.

   - Resolution of times settings: ½ cycle.

   - Readout of the RMS weld current and of the first cycle, positive and negative half wave.

   - All inlets and outlet are galvanic insulated.

   - Set and run of 4 programs: 1 and 2 are associated to welding clamp A -IC1-; 3 and 4 are associated to welding clamp B -IC2-.

   - Line voltage compensation available in V% and I% modes.

   - Serial communication line interface RS232 point to point for connection to a printer or to a PC.

   - Start cycle with concomitance (dual push button) or with footswitch.

   - Monitoring (Quality control) of weld current limits or of firing angle available in spot-weld and IK or I% modes.

   - Programmable function of continuous weld current auto increase under variable curve for each welding clamp to compensate the electrodes consumption.

   - Independently programmable first insertion delay and first insertion delay after a pause.

   - Four solenoid valves associated to weld clamp A and B for presqueeze and squeeze phases.

   - Prestroke solenoid valve for each weld clamp.

   - Automatic power line frequency recognition.

   - Three language setting capability; further languages upon request.

   - Possible drive from a PLC. - Secondary current measurement with Rogowsky coil or primary current measurement with current transformer.

   - L x W x H: 360 x 133 x 91 mm
