- 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
