13 Pulse Hz (Frequency) Indicator (AC and DC TIG Pulse Modes only)
Pulse indicator will illuminate when set pulse frequency (AC and DC Pulse TIG modes only). Refer to
Section 5.03 in the Programming Mode for further detail.
14. Programming Parameter Indicators
These indicator lights will illuminate when programming.
15. Digital Parameter Meter
The digital meter is used to display the actual output current of the power source. It is also used to display
Parameters in Programming Mode.
Depending on the Programming Parameter selected, the status indictor adjacent to the digital meter will
illuminate to show the units of the programming parameter. This value can be adjusted by varying the
multifunction control when the desired Programming Parameter Indicator illuminates.
At times of non-welding, the amperage meter will display a pre-set (preview) amperage value.
When welding, the meter will display actual welding current.
Should a remote device be connected the maximum setting of the power source will be determined by
the respective front panel control, irrespective of the remote control device setting. As an example, if
the output current on the power source front panel is set to 50% and the remote control device is set to
100%, the maximum achievable output from the unit will be 50%. Should 100% output be required, the
respective power source front panel control must be set to 100%, in which case the remote device will
then be able to control between 0-100% output.
16. VRD ON/OFF Indicator
A VRD (voltage reduction device) is a hazard reducing device designed to reduce electric shock hazards
present on the output of welding power source when operating in MMAW (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 MMAW (stick) mode.
The green VRD ON light illuminates (red light is off) when the VRD is active. Under this condition the
open circuit voltage of the unit is limited to below 35V DC, thus reducing the potential of serious electric
shock (such as when changing electrodes).
The red VRD OFF light illuminates (green light is off) 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 35V DC.
17. Spot Welding Indicator
When the selected process is Spot Welding the Spot indicator illuminates. Refer to Section 5.03 in the
Programming Mode for further detail.
18. Pulse Width Indicator
Pulse Width is a parameter to adjust the ratio of the peak current time during each pulse cycle. Turn the
Multifunction Control Knob in programming mode, and adjust pulse width when the % Pulse indicator
illuminates. Refer to Section 5.03 in the Programming Mode for further detail.
19. AC Balance Indicator
The AC Balance sets the balance of AC wave form in AC TIG mode. Turn the Multifunction Control Knob
in programming mode, and adjust AC Balance when the indicator illuminates. Refer to Section 5.03 in
the Programming Mode for further detail.
