VRD Indicator
A VRD (voltage reduction device) is designed to reduce electric shock hazards present
on the output of welding power source when operating in STICK mode. Note that the
presence of VRD should not be used as a substitute for the use of appropriate safety
practices as indicated in section one of this manual.
Both the green and red indicator lights only operate in STICK mode.
The green VRD ON light illuminates when the VRD is active. Under this condition the
open circuit voltage of the unit is limited to below 24V DC, thus reducing the potential
of serious electric shock (such as when changing electrodes).
The red VRD OFF light illuminates when the VRD is inactive. Under this condition the
output voltage of the unit will be at welding potential which in some cases may
exceed 24V DC.
Fault Indicator
The yellow fault indicator will be illuminated when any of the faults are detected. All
Faults will illuminate the indicator.
Left Multifunctional Data Display
MIG Mode
This digital meter is used to display the pre-set (preview) Wirefeed Speed in Inches Per
Minute (IPM) in MIG mode and actual welding amperage of the power source when welding.
At times of non-welding, the digital meter will display a pre-set (preview) value of Wirefeed
Speed. This value can be adjusted by varying the Left Knob.
STICK and LIFT TIG Modes
The digital meter is used to display the pre-set (preview) amperage in STICK / LIFT TIG modes
and actual welding amperage of the power source when welding. At times of non-welding,
the amperage meter will display a pre-set (preview) value in both STICK and LIFT TIG modes.
This value can be adjusted by varying the Left Knob. When welding, this digital meter will
display actual welding amperage in all modes.
At the completion of welding, the digital meter will hold the last recorded amperage value for
a period of approximately 7 seconds in all modes. The amperage meter will hold the value
until; (1) any of the front panel controls are adjusted in which case the unit will revert to
preview mode, (2) welding is recommenced, in which case actual welding amperage will be
displayed, or (3) a period of 7 seconds elapses following the completion of welding in which
case the unit will return to preview mode.
