STITCH/CONTINUOUS: Selects between cyclic (Stitch) welding and continuous welding or cutting.
a) CONTINUOUS - Selects continuous welding or cutting.
b) STITCH - Selects the cyclic (Stitch) welding mode. This mode consists of four continuously repeated steps.
1) The machine stops moving for the selected time to perform Puddle
Buildup. (PIERCE WHEN PLASMA CUTTING)
2) The machine welds at the selected welding speed for the time selected
using the Weld Time control.
3) The machine stops moving for the selected time to perform Crater Fill.
4) The machine turns off the welder and moves at maximum speed to
where the next weld needs performed. This location is determined by
setting a Skip Time control.
WELD TIME: This control functions only when the mode switch is set to Stitch. Weld time sets a weld
length time from 1-50 seconds. This corresponds to a weld length of approximately 0.03-100 inches (0.8-
2540 mm). NOTE: The operator must manually enable the weld contactor by turning on the Weld Contact
or the welder will never cycle on and off.
SKIP TIME: This control functions only when the mode switch is set to Stitch. Skip time sets how long the
machine travels between welds (0.3-15 seconds). This corresponds with a skip length of approximately 0.6-
30 inches (15-762 mm). The machine always moves between welds at maximum speed.
PUDDLE BUILDUP / CRATER FILL TIME: This control functions only when the mode switch is set to
Stitch. Puddle Buildup/Crater Fill Time sets the time the machine is stopped at the beginning and end of
every weld (0-1.5 sec).
