LiftArc™
The LiftArc™ function strikes the arc when the electrode is brought into contact
with the workpiece and then lifted away from it.
Striking the arc with the LiftArc™ function:
1. The electrode is touched on to the workpiece.
2. The trigger switch is pressed, and a low current starts to flow.
3. The welder lifts the electrode from the workpiece: the arc strikes, and the current rises
automatically to the set value.
LiftArc™ is activated in the main menu → start method.
Live TIG-start
With “Live TIG start” the arc strikes when the tungsten electrode is brought into contact with
the workpiece and then lifted away from it.
- Activation of “Live TIG-start” performed in the process menu.
2-stroke
A = Gas pre-flow
B = Slope up
C = Slope down
D = Gas post-flow
Functions when using 2 stroke control of the welding torch.
In the 2 stroke control mode, pressing the TIG torch trigger switch (1) starts gas pre-flow (if
used) and strikes the arc. The current rises to the set value (as controlled by the slope up
function, if in operation). Releasing the trigger switch (2) reduces the current (or starts slope
down if in operation) and extinguishes the arc. Gas post-flow follows if it is in operation.
2-stroke is activated in the main menu → trigger mode or in the measure screen.
