FCAW/GMAW START/END SETTINGS
FIGURE B.11
1.
Set all to Auto – Start/end se�ngs are set to “auto” by default. These se�ngs are programmed
based on process and setpoint to provide ideal welding. The se�ngs may be adjusted if desired.
2.
Run-In – Allows adjus�ng the wire feed speed prior to the arc being established. A low run-in
speed permits smooth arc starts. A�er the arc is speed will change from run-in to welding wire
feed speed. The run-in op�on is available in MIG and FCAW modes.
3.
Pre-Flow Time - Adjusts the �me that shielding gas flows before the welding output turns on.
4.
Start Time – Controls the WFS and Volts for a specified �me at the beginning of the weld.
During the start �me, the machine will ramp from the Start Procedure to the preset Welding

edure.
5.
Crater Time – Controls the WFS and voltage for a specified �me at the end of the weld a�er the
trigger is released. During the Crater �me, the machine will ramp from the Weld Procedure to
