Limitation of the percental current change
In the "disabled" position, the operator can not adjust or delete existing procedure sequences.
If it is necessary, however, to make small adjustments for a welding task (e.g. due to batch-based fluctuations of the
material composition or minor changes in the wall thickness), a percental limit can be set in the welding procedure. The
operator can adjust the current within this limit.
This adjustment is not saved in the procedure and affects all sectors and the high-pulse and low-pulse current.

Recommendation:
Allow for max. 10% (20% adjustment range).
Specifying "5%" means that it is possible to adjust up to 5% above or below the base value. The total adjustment range
is 10%.
Specifying a limit
1. Unlock machine with key switch.
The main menu "long form" appears in the display.
2. In the main menu, select "
System settings
" > "
Program settings
".
3. Select and highlight "
Limit for correction factor
" field and enter a percental value.
– or –
If no adjustment is desired: Enter value "0".
4. Save procedure.
5. Lock machine with key switch.

Tacking function
1. Select test mode or weld mode with softkeys 1 or 2.
2. Select "
pool formation
" with "
go backward...
" or "
go forward...
".
3. Select the "
Yes
" option for "
Tacking
".
The following four fields are activated:
4. Accept or adjust suggested parameters.
5. Test tacking function: Carry out welding on a test pipe.
6. Interrupt test weld with "Stop" after the tacking phase.
7. Remove sample pipe from the weld head and assess tacking.
8. Adjust parameters manually if necessary.
Tack points
Number of tack points on the pipe. The system calculates the optimum position of the points from the specified number of
points and moves to them during the tacking procedure: With four tack points, the two opposite tack points (0° and 180°)
come first, followed by the other points (90° and 270°).
Tack current
Presetting: High-pulse current from level 1.
During the tacking procedure, this current is switched on after the position for the respective tack point (with rotor not
moving) is reached. If the time specified under "Tack time" has past, the system switches to a low current (the "
pilot
current
") and moves to the next tack point at the maximum possible speed.

In case of weak tacking: Lengthen tacking time or increase tack current.
