Main Features:

   - Synchronous welding control using silicon controlled rectifiers for the regulation of the weld current by mean of phase cut off procedure.

   - The response speed is within 2 cycles for the first weld, and then 1 cycle for every successive weld. Three different control modes are available:

•  Voltage percentage V‰
•  Current percentage I‰ (set in feed – forward referred to the max. current of the transformer)
•  Constant current IK (1.0 – 99.0 KA)

    - Suitable for machines with single phase and three phases welding transformer.

   - Management of spot-weld cycles and seam weld cycles.

   - The resolution of times settings is 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 capability of 64 programs.

   - 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 (twin push button) or with footswitch.

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

   - Programmable function of continuous weld current auto increase under variable curve.

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

   - Automatic power line frequency recognition.

   - Three languages choose capability; further languages upon request.

   - Signals for control trough external PLC.

   - Secondary current measurement with Rogowsky coil or primary current measurement with current transformer.

   - Sizes - L x W x H: 360 x 133 x 91 m
