Display - 3-1/2 digit 7-segment LED with (+) or ( - ) polarity indicators. .56” (14.2mm) character height. Displays arc voltage in volts, wire speed in IPM or m/m and all timers in seconds.

Indicator Lights - Extra bright red LED’s for viewing at almost any angle. Always indicates the mode being used and which function or timer is beiing displlayed.. A function and a timer light will never be on at the same time since they can only be displayed one at a time.

voltage while welding (as indicated by top light “blinking”). The power source automatically determines whether preset voltage or percent trim will be displayed, and adjustable with Volts/Trim rotating encoder control.

Middle Light - Indicates Run-in speed is being displayed. As shipped, these models are setup for a 50 IPM (1.27m/min) fixed run-in speed with display function deactivated. They may be user-selected to activate or deactivate adjustable Run-in display.

Bottom Light - Indicates Weld Feed Speed (WFS) is being displayed, and is adjustable with the Wire Feed Speed rotating encoder control.

Cold Feed key energizes the wire

feeder but not the power source or

solenoid valve. Cold feed speed is

adjustable and is displayed only while pressing Cold Inch, and the last speed selected is stored in memory for next Cold feeding.

Gas Purge key energizes the solenoid valve but not the wire feeder or power source.

Timer/Crater Select key enables operator to choose spot or gas timers, or crater speed as indicated by the appropriate light. Pressing the key causes lights to sequence (left to right, top to bottom) starting from the current indicated selection. Any parameter not available in the mode selected is skipped over.

Top Left Light - indicates preflow time is being displayed in seconds.

Top Right Light - indicates postflow time is being displayed in seconds.

Middle Light - indicates Crater Feed Speed is being displayed. This display will only occur if 4-step mode with crater fill is selected.

Bottom Light - indicates spot on time is being displayed in seconds.

Top Light - Indicates 2 - step

(standard) trigger mode.

Middle Light - Indicates 4 - step

(lock) trigger mode. This mode may

be selected to include crater fill or

weld current interlock.

Bottom Light - Indicates spot weld

mode.

Increase arrow key increases the setting of the parameter selected to be displayed. Arrow keys do not function for Wire Feed Speed or Volts/Trim settings, which are adjusted using the rotating encoder knobs.

Decrease arrow key decreases the setting of the parameter selected to be displayed. Arrow keys do not function for Wire Feed Speed or Volts/Trim settings, which are adjusted using the rotating encoder knobs.
