13. LOWER DISPLAY — This display shows numerical
information for schedule number, amps, WFS, and
weld sub segment during normal operation. It can also
contain diagnostic test information when diagnostic
are performed.
14. TEST LED — When lit, the control panel is in a test
mode. The test mode allows the weld operator to per-
form the weld schedule with all of its control signals,
timing, and displayed voltages and wire feed speeds.
However the wire feeder and power source will not
operate.

panel in and out of test mode. This button has no
effect during a weld.
16. PURGE BUTTON — Depressing the purge button will

10. AMPS LED — When lit, the lower display will show
actual weld current in amps.
NOTE
To have the lower display show amps instead

wire feed speed. If the unit is being programmed, this
number represents the programmed wire feed speed.
If the system is welding, the value displayed is actual
wire feed speed.
NOTE
The unit comes from the factory with the WFS
displayed in inches per minute (IPM). The WFS
can be displayed in meters per minute (MPM).
Refer to the Operation - Softswitch Descrip-
tion chapter of this manual.
