8. Left Digital Display
Left display is a 4- digit display.
In advanced programming mode, this display is used to display advanced features details or simply "----". Please refer
to Section 4.03 for Advanced Features Details.
When welding, this digital meter will display WFS in Inches Per Minute (IPM) or Meters Per Minute (MPM) and actual
welding amperage of the power source; it can also simply display "----" when the VAF-4 is connected to a power source
without a control signal on pin U of the 19 pin interconnection. The VAF-4 uses this signal on pin U of the 19 pin
interconnection to display welding amps, if this signal is not present from the power source, set the display to show
"----". Press left knob and select the information on left display. At times of non-welding, the digital meter will display
a pre-set (preview) WFS value. This value can be adjusted by turning the Left Knob (Control No. 6).
At the completion of welding, the digital meter will hold the last recorded value for a period of approximately 10 sec-
onds. The 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 10 seconds elapses following the completion of welding in which case the unit will return to preview mode.
The display is also used for providing error messages to the user. Please refer to Section 5.01 for Error Codes and
Remedies.
9. Right Digital Display
Right display is a 4- digit display.
This digital meter is used to display the pre-set (preview) Voltage in MIG mode and actual welding voltage of the power
source or simply "----" when the VAF-4 is connected to a power source without a control signal on pin C of the 19
pin interconnection. The VAF-4 uses this signal on pin C of the 19 pin interconnection to display welding volts, if this
signal is not present from the power source, set the display to show "----". Press right knob and select the information
on right display. At times of non-welding, the digital meter will display a pre-set (preview) value of Voltage. This value
can be adjusted by turning the Right Knob (Control No 7).
At the completion of welding, the digital meter will hold the last recorded voltage value for a period of approximately
10 seconds in all modes. The voltage 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 voltage
will be displayed, or (3) a period of 10 seconds elapses following the completion of welding in which case the unit
will return to preview mode.
The display is also used for providing error messages to the user and showing other information. Please refer to Sec-
tion 5.01 for Error Codes and Remedies.
10. 2T - 4T- SPOT Trigger Mode Control Button
Press and release the button to change the selected operating mode of the trigger. The selected mode can be “2T”,
“4T” or "Spot” operation. The red indicator next to the button will illuminate to identify which mode is selected. In the
4T mode once the weld has been started you can release the trigger and continue welding until the trigger is activated
again or the welding arc is broken to stop the welding arc. Please refer to Section 4.19 - 4.22 for more details.
