16. BACKGROUND AVC - Sets the Arc Voltage value in each level during the BACKGROUND
PULSE time.
17. AVC MODE
CONTINUOUS - Regulates the Arc Voltage to the Primary AVC value during primary and
regulates the arc voltage to the Background AVC value during the background pulse.
SAMPLE ON THE PRIMARY - Regulates the arc voltage servo to the Primary AVC value
during Primary pulse and turns the AVC servo (and motor) OFF during the Background.
SAMPLE ON THE BACKGROUND - Regulates the arc voltage servo to the Background
AVC value during the Background pulse and turns the AVC servo (motor) OFF during the
Primary pulse.
OFF - Turns the AVC servo OFF and does not attempt to regulate the Arc Voltage.
18. AVC RESPONSE - Sets a value that determines how fast the AVC responds to errors in
the arc voltage value versus the programmed AVC value (primary and/or background).
19. OSC IN DWELL TIME - Sets the time that the Oscillator will be in the IN Dwell position
20. OSC OUT DWELL TIME - Sets the time that the Oscillator will be in the OUT Dwell position
21. OSC EXCURSION TIME - Sets the time that the Oscillator will take to move from the IN to
the OUT and the OUT to the IN.
22. OSC AMPLITUDE - Set the distance that the Oscillator moves from OUT to IN and IN to
OUT. User defines by weld head type the amplitude range.
23. OSC MODE -
ON - Allows the Oscillator to move at the Dwell/Excursion rate and Amplitude distance.
OFF - The OSC servo is only used for steering and does not move during sequence.
4.2. SINGLE LEVEL FUNCTIONS and MODES
1. PREPURGE - The time that gas flows to the torch after Sequence Start and before arc start.
2. START MODE - Can be set to RF Start or Touch Start.
3. TRAVEL MODE - Determines which direction Clockwise or Counter Clockwise or OFF the
Travel Servo will drive the motor when the Travel Servo is enabled.
4. UPSLOPE - Sets the time that the Current and the Oscillator will take to rise to Level I
maximum values after arc start.
5. TRAVEL START DELAY - Sets the time from Arc Start until the Travel Servo is enabled.
6. WIRE FEED START DELAY - Sets the time from Arc Start until the Wire Feed Servo is
enabled.
7. PRIMARY WIRE FEED PULSE DELAY - Sets the amount of time the Wire Feed can be
delayed from changing to the Primary value from the Background value.
8. AVC START DELAY - Sets the time from Arc Start until the AVC Servo is enabled.
9. DOWNSLOPE - Sets the time that the Current and Oscillator will take to fall to minimum
programmable values before the arc goes out and Postpurge begins.
10. TRAVEL STOP DELAY - Sets the time the Travel Servo remains enabled after the
beginning of Downslope.
11. WIRE FEED STOP DELAY - Sets the time the Wire Feed Servo remains enabled after the
beginning of Downslope.
12. AVC STOP DELAY - Sets the time the AVC Servo remains enabled after the beginning of
Downslope.
13. POSTPURGE - Sets the time that gas continues to flow to the torch after the end of
Downslope and the arc has gone out.
4.3 MISCELLANEOUS NON-PROGRAMMABLE FUNCTIONS
1. Return to Home - System can be set up, by weld head type, to automatically at the end of
Post Purge, jog the Travel Servo and move the torch to the mount/dismount position or
starting position for next pass.
2. Autowrap function - System can be set up, by weld head type to allow the operator to
engage the autowrap function and wrap the cables prior to the start of weld sequence.
