6.3.5 VRD function
Warning! The electrical connection of the machine must be completed by
electricians with qualification certificates.
Warning! Electric shock may cause death; after power failure, the machine
will still have high voltage, so do not touch the live parts.
The MMA VRD mode is enabled by default in the factory settings, and the user can disable it
as required.
1) Open the left cover of the machine with the machine powered off.
2) Turn the DIP switch SW1 to "12" on the panel PN-212(TIG200P PFC/TIG200PFC) or
PN-213(TIG200P/TIG200) to disable VRD.
3) Put the cover back and turn on the power; switch to MMA mode and the VRD indicator
will be on. At this time, the no-load voltage of the welder is 11.5V.
