VRD is short for Voltage Reduction Device. VRD reduces the welding power source’s
open circuit voltage (OCV). OCV is the voltage measured across the terminals when
not welding. The VRD unit will turn on welding power when the resistance between
the electrode and work is less than 200 Ohms (typically metal to metal contact).
This means that during non-arcing periods (when not welding), the chance of being
electrocuted from the secondary welding circuit has virtually been eliminated.
This complete new CIGWELD range of inverter welding power sources now incorporate
a standards compliant voltage reduction device (VRD) as a standard feature.
No more ‘Bolt ons’or ‘Retro fits’, this superior integrated VRD technology is the
future in welding safety. . . today. Additionally, the application of state of the
art fully digital microprocessor technology ensures superior arc characteristics
across all the processes, especially in the manual arc stitch welding mode during
critical arc starting and re-striking phases.
When it comes to safety in welding the answer is VRD When it comes to VRD the answer
is CIGWELD Superior integrated VRD technology

1. The machines listed are all CC output only (excluding Transmig 400i), therefore
the only possible way to set up the MIG or Fluxcored process is via a voltage sensing
wire feeder such as the VSF-2.
