Top Light - Indicates gun trigger has been selected to perform the Cold Feed Forward function in exactly the same manner as Cold Feed Forward key (See Operation Keys - Cold Feed Keys) with the same memory stored adjustable speed setting, and “Cld” shown on the Voltage display.

Second Light - indicates 2-step (standard) trigger mode.

1.Trigger closure energizes the solenoid valve, then the wire feeder and the power source after Preflow time.

2.Releasing the trigger turns off the wire feeder, then power source after burnback time and then the gas solenoid valve after Postflow time.

Third Light - indicates 4-step (lock) trigger mode. This mode may be selected to include or exclude weld current interlock. (See “4-Step Trigger Mode Operation Selection” in this section for 4 step Trigger Mode operation)

Bottom Light - indicates Spot Weld Mode, which will only light if a spot time is set (See “Display Control Keys” in this section). If set to 0.0 seconds, spot mode light selection will be skipped. Trigger closure energizes the gas solenoid valve, then wire feeder and the power source. The spot timer starts when current flows. The wire feeder and power source then solenoid valve are all turned off when the spot on timer times out even though the trigger is opened or is still closed. Preflow/Postflow and burnback timers are also functional in spot mode. (See “Display Control Keys” in this section).

TIMER Timer Select key - enables operator to choose burnback, spot or gas timers, as indicated by the appropriate light. Pressing the key causes lights to sequence (top to bottom, then all off) starting from the

current indicated selection.

When a timer is selected the Voltage display shows the time setting in seconds, as indicated by “SEC” dis- played on the speed display. The times are set using the Voltage encoder knob.

Second Light - indicates spot time is being displayed, set 0.0 (as shipped) to 199.9 seconds.

Third Light - indicates burnback time is being dis- played, set 0.00 (as shipped) to 0.25 seconds. This is the time the arc power is delayed at the stop of the weld, and should be set to the lowest time required to prevent the wire sticking in the weld.

Bottom Light - indicates postflow time is being dis- played, set 0.0 to 10.0 seconds (0.5 sec as shipped).

This is the time the shielding gas flows after the wire feed and power source are deactivated.

Pressing Timer Select Key again, or closing the gun trigger, shuts all timer lights off, indicating weld Voltage and Wire Feed Speed are again being dis- played, and set by the appropriate encoder knob.
