GENERAL PROGRAMMING MODE
While the carriage is stopped, i.e. not in a weld cycle, press the program push button for a
minimum of one (1) second but no more than seven (7) seconds to go from the main screen to
the General Programming Screen 1.
To navigate between the first and second general programming screens press the Auto Cycle
Stop push button.
Screen 1:
Shielding Gas Pre-Flow Duration: This is a time delay that allows
the shielding gas to flow before the wire feeder starts. Adjustable
range, 0.0 to 9.9 seconds in 0.1 increments. Factory set at 0.5
seconds
Wire Feed Soft Start Speed: This is the initial wire feed speed prior
to establishing the arc. Once the arc has been established, the wire
feeder runs at the Actual Wire Feed Speed as set by the remote
pendant. The adjustable range is 50 to 1200 I.P.M. or 127 to 3048
Cm.P.M. Factory set at 158 I.P.M. or 401 Cm.P.M.
Screen 2:
Weld Travel Delay: This is an adjustable time delay for carriage travel.
Once the arc has been established the carriage will commence travel
after the programmed delay has been reached. Adjustable range 0.0 to
9.9 seconds in 0.1 increments. Factory set at 0.3 seconds
Crater-Fill Duration: This is an adjustable time delay that allows the
welding to continue after the carriage travel has ceased. Adjustable
range 0.0 to 9.9 seconds in 0.1 increments. Factory set at 0.5 seconds
Burn-Back Duration: This is a small, adjustable time delay between stopping the wire feed
motion and deactivating the weld contactor signal, thereby preventing the wire from solidifying in
the weld. Adjustable range 0.00 to 9.99 seconds in 0.01 increments. Factory set at 0.01
seconds
Shielding Gas Post-Flow Duration: This time delay allows shielding gas to continue to flow
after the burn-back function has completed. Adjustable range 0.0 to 9.9 seconds. Factory set at
0.5 seconds.
