4-stroke
A = Gas pre-flow
B = Slope up
C = Slope down
D = Gas post-flow
Functions when using 4 stroke control of the welding torch.
In the 4 stroke control mode, pressing the trigger switch (1) starts gas pre-flow (if used). At
the end of the gas pre-flow time, the current rises to the pilot level (a few ampere), 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 activated in the main menu → trigger mode or in the measure screen.
Current
A higher current produces a wider weld pool, with better penetration into the workpiece.
The current is set in the measure screen, weld data setting , or fast mode menus.
Only applies to TIG welding with constant current.
Pulse current
The higher of the two current values in the event of pulsed current. When pulsing, slope up
and slope down are also pulsed.
Pulse current is set in the weld data setting menu.
Only applies to TIG welding with pulsing.
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 to TIG welding with pulsing.
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 to TIG welding with pulsing.
Background time
Time for background current which, along with the time for pulse current, gives the pulse
period.
Background time is set in the weld data setting menu.
Only applies to TIG welding with pulsing.
