OPERATING MANUAL
Downslope screen
Move the cursor and enter values with the control knob.
Press Next when complete.
• Downslope Delay: downslope of weld current
will occur immediately at the tie‐in of the start
location. If you want an overlap of the weld bead,
set the seconds of downslope delay.
• Downslope: downslope or current taper time
period in seconds.
• Wire Stop Delay: (for use with weld heads
with wire feeders only) wire feed is normally
terminated at the initiation of downslope. The
wire stop delay feature delays the termination of
wire feed for an adjustable period (in seconds)
after downslope is initiated. It is useful when
welding crack‐sensitive materials such as alloys
with high nickel content.
• Pulsing Downslope: choice of pulse current or
steady-state current during downslope period
(Yes or No)
• Final Amps: weld current level just prior to arc
termination
• Post‐purge: period gas ows after arc termination
(seconds)
• Auto Rewind: if “switched on” (by selecting Yes on
the display), the weld head automatically rewinds
at completion of a weld and comes to a halt at
the starting rotational position. Post‐purge occurs
simultaneously with auto rewind.
• AGC Stop Delay: AGC operation normally turns o
at the initiation of downslope. This feature delays
the termination of AGC for an adjustable period
(seconds) after downslope as been initiated.
Save Weld/Next Weld
Use cursor to select item, control knob to modify. You
have two alternatives:
1. Repeat the weld program. At the completion of a
weld, the same program is automatically loaded so
that you do not need to re-enter the weld number.
2. Run a dierent weld program to create readymade
work cycles. Press Next when nished.
