Tacking function

Activating and setting the tacking function is described in the
section on page 52.
The tacking function is only available for the TIG DC welding process.

After the tAC time has elapsed, welding continues at a constant welding current, and any
pulsing parameters that may have been set are available.
When a time period is specified for the tAC (tacking) setup parameter, the tacking
function is assigned to all operating modes
The basic operating sequence of each of these modes remains unchanged
During the specified period, there is a pulsed welding current that makes the weld pool
run together better when two components are being tacked.

NOTE! The following points apply to the pulsed welding current:
- The power source automatically regulates the pulsing parameters depending
on the specified main current I-1
- There is no need to set any pulsing parameters
