In 4--stroke control mode, pressing the trigger switch starts gas pre--flow (if used) (1).
At the end of the gas pre--flow time, the current rises to the pilot level (a few
amperes), and the arc is struck. Releasing the trigger switch (2) increases the
current to the set value (with slope up, if in use). At the end of welding, the welder
presses the trigger switch again (3), which reduces the current to pilot level again
(with slope down, if in use). Releasing the switch again (4) extinguishes the arc and
starts gas post--flow.
-- 4--stroke is enabled in the
measure image or the main menu
.
5.2.5
Current
A higher current produces a wider weld pool, with better penetration into the
workpiece.
Current is set in either the
measure image, the weld data setting menu,
or
the fast mode menu
.
Only applies for TIG welding with constant current.
5.2.6
Pulse current
The higher of the two current values in the event of pulsed current. By pulsing the slope
up and slope down will also be pulsed.
-- Pulse current is set in the
weld data setting menu
.
Only applies for TIG welding with pulse.
5.2.7
Background current
The lower of the two current values in the event of pulsed current.
-- Background current is set in the
weld data setting menu
.
Only applies for TIG welding with pulse.
5.2.8
Pulse time
The time the pulse current is
on
during a pulse period.
-- Pulse time is set in the
weld data setting menu
.
Only applies for TIG welding with pulse.
