be fed during the entire slope-off time.
Since the introduced energy declines as the current slopes off, the wire feed should stop when there is no longer a melt pool.
Wire retract: Time during which the wire running direction is reversed at the end of the wire feed so that the wire does
not rest on the pipe when turning back the weld head. The retraction time should be approx. 1–2 sec. and is set
properly when the wire extends 2–3 mm from the feed tube after retraction. If the time is too long, the wire is pulled in
completely and the end (which is usually still a liquid ball) can adhere to the wire feed tube.
Wire HP/LP Speed : The wire feed speeds of the filler wire (in mm/min) in the individual sectors. Auto programming usu-
ally controls the wire in sync with the pulse: The wire feed motor does not move on the low pulse, as the energy of the
arc may not be sufficient to melt the wire under certain circumstances here.
To achieve a higher deposition rate:
X Increase speed of the wire in the high-pulse phase.
– or –
X
Feed wire in the low-pulse phase as well. The weld current set for low pulse must be sufficient here.
1. In the main menu, select "Manual/Adjust programming" > "Adjust parameters" > "Pool formation".
2. Select, highlight, adjust and save the "Wire start delay", "Wire final delay time" and "Wire retract" parameters.
3. Select "go forward to sector 1" or select the desired sector.
The respective selected sector is highlighted in color to the right in the display. The angular degree of this sector is
specified. An image of the seam scale appears below the process graphic.
4. Select, highlight, adjust and save the "Wire HP Speed" and "Wire LP Speed" parameters.
5. Press softkey 1 ("Weld") or softkey 2 ("Test").
The machine is ready to start.
8.3.10 Changing the sector
Auto programming divides welding into different sectors (usually four to six). The parameters can be programmed for
each sector. The sector borders can be shifted manually, and sectors can be added or deleted.
Adjusting sector borders with the rotary knob
1. In the main menu, select "Manual/Adjust programming" > "Devide into levels".
The sector list appears on the left in the display (five sectors in the example, see Fig. 24). The process sequence ap-
pears on the right.

2. Turn rotary knob until the pointer points to a white sector border.
The green pointer moves through the sector, and the degree information of the position appears at the bottom edge of
the process representation.
3. Ensure that the pointer is positioned correctly. For this purpose, compare value in the sector list (end sector 1 =
90°) with the degree information.
