the workpiece and then lifted away from it.

. Step 1: the electrode is touched on to the workpiece.
Step 2: the trigger switch is pressed, and a low current starts to flow. Step 3: the welder lifts the
electrode from the workpiece: the arc strikes, and the current rises automatically to the set value.
2-stroke
With 2-stroke gas pre-flow (if used) starts when the welding gun trigger switch is
pressed. The welding process then starts. Releasing the trigger switch stops weld­
ing entirely and starts gas post-flow (if selected).
Gas pre-flow Slope
up Slope down 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.
