Functional characteristics TIG welding 5.1.4.5 spotmatic In contrast to the spotArc operating mode, the arc is not ignited by pressing the torch trigger as is usual, but by briefly touching the tungsten electrode against the workpiece. The torch trigger is used for welding process activation.

Selecting the process activation type for the welding process > see 5.7 chapter. Up-slope and down-slope times possible for long spot time setting range (0.01–20.0 s) only.
5.1.5 TIG activArc welding The EWM activArc process, thanks to the highly dynamic controller system, ensures that the power sup- plied is kept virtually constant in the event of changes in the distance between the welding torch and the weld pool, e.g. during manual welding. Voltage losses as a result of a shortening of the distance between the torch and molten pool are compensated by a current rise (ampere per volt - A/V), and vice versa.

Functional characteristics MMA welding 5.2.2 Hotstart The function hot start ensures a secure igniting of the arc and a sufficient heating to the still cold parent metal at the beginning of the welding process. The ignition takes place here with increased current (hot start current) over a certain time (hot start time).
Functional characteristics MMA welding 5.2.3 Arcforce During the welding process, arcforce prevents the electrode sticking in the weld pool with increases in current. This makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular. Figure 5-36 5.2.4 Antistick...
