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. Activation is indicated by flashing of the spotArc/spotmatic signal light. The process
can be activated separately for each spot or also on a permanent basis. The setting is controlled using
the
process activation parameter in the configuration menu
> see 5.6 chapter
:
• Separate process activation (
>
):
The welding process has to be reactivated for every arc ignition by pressing the torch trigger. Process
activation is automatically terminated after 30 s of inactivity.
• Permanent process activation (
>
):
The welding process is activated by pressing the torch trigger once. The following arc ignitions are ini-
tiated by shortly touching the tungsten electrode against the workpiece. Process activation is termina-
ted either by pressing the torch trigger again or automatically after 30 s of inactivity.
For spotmatic the separate process activation and the short spot time setting range are enabled by
default.
Ignition by touching the tungsten electrode against the workpiece can be disabled in the machine configu-
ration menu with parameter
. In this case the function works as with spotArc, but the spot time setting
range can be selected in the machine configuration menu.
The duration is set in the machine configuration menu using parameter
