Functional characteristics TIG welding 5.1.2 Welding task selection The setting of the tungsten electrode diameter has a direct influence on the machine functionality, TIG ig- nition behaviour and minimum current limits. The ignition energy is controlled by the set electrode diame- ter.
Functional characteristics TIG welding 5.1.2.1 Recurring welding tasks (JOB 1-100) The user has 100 additional memory locations at their disposal to save recurring or different welding tasks on a permanent basis. To do so, simply select the required memory location (JOB 1-100) and set the welding task as described previously.
Functional characteristics TIG welding 5.1.3.2 Tungsten balling function The tungsten balling function provides optimum tungsten balling, ensuring that the best ignition and welding results are achieved during AC welding. Optimum tungsten balling requires a sharpened electrode (about 15–25°) and the set electrode diameter on the machine control.

Functional characteristics TIG welding 5.1.5.5 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.
5.1.6 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 TIG welding 5.1.8.2 Thermal pulsing The operation sequences basically match the standard welding sequences, but there is an additional switching back and forth between the main current AMP (pulse current) and the secondary current AMP% (pulse pause current) at the set times. Pulse and pause times and the pulse edges ( ) are en- tered in seconds on the control.

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. EXIT Figure 5-44 5.2.4...
