9.3.1 Gun trigger mode (2-stroke/4-stroke)
2-stroke
A = Gas pre-flow
B = Hot start
C = Welding
D = Crater fill
E = Gas post-flow
Functions when using 2-stroke control of the welding torch.
Gas pre-flow (if used) starts when the welding gun trigger switch is pressed (1). The welding
process then starts. When the trigger switch is released (2), crater filling starts (if selected)
and the welding current is stopped. Gas post-flow starts (if selected).
TIP: Pressing the trigger switch again while crater filling is in progress continues crater filling
as long as the switch is held depressed (the dotted line). Crater filling can also be interrupted
by quickly pressing and releasing the trigger switch while it is in progress.
2-stroke is activated in the measure screen, the configuration menu or with a soft key in the
measure screen.
4-stroke
There are 3 start and 2 stop positions for 4-stroke. This is start and stop position 1. When
resetting, position 1 is selected. See the “4-stroke configuration” section.
A = Gas pre-flow
B = Hot start
C = Welding
D = Crater fill
E = Gas post-flow
Functions when using 4-stroke control of the welding torch
Gas pre-flow starts when the welding gun trigger switch is pressed (1). Releasing the trigger
switch starts the welding process. Pressing the trigger switch again (3) starts crater filling (if
selected) and reduces the welding data to a lower value. Releasing the trigger switch (4)
stops welding entirely and starts gas post-flow (if selected).
TIP: Crater filling stops when the trigger switch is released. Keeping it held in instead
continues crater filling (the dotted line).
4-stroke is activated in the measure screen, the configuration menu or with a soft key in the
measure screen. It is not possible to select gun trigger mode (4-stroke), if spot welding is
ON.
