Configuring the welding machine for mechanical arc fusion welding

5.8 Configuring the welding machine for mechanical arc fusion welding
Before the welding machine is commissioned it has to be configured for mechanical arc fusion welding
(cold or hot wire welding). The following basic settings are made in the Expert
menu > see 5.9.16 chapter:
1. Activate filler wire process (AW = on).
2. Hot wire or cold wire selection (HW = on/off)
In addition, wire diameter and wire return can be adjusted if required.
5.8.1

Selecting a welding task by means of the JOB list

Select material, tungsten electrode  and seam position on the welding machine controls.
•
The welding task number (JOB number) results from the chosen basic parameters. If no wire
speed is assigned to this JOB-number ( > see 10.1 chapter), wire feeding will not take place. In
order to carry out the chosen welding task, the wire feed unit must be switched to the MANUELL
operating mode > see 5.8.2 chapter.
5.8.2

Select wire speed operating mode (KORREKTUR / MANUELL)

The wire speed can be set in two different operating modes:
MANUAL:
CORRETION:
In the wire feed unit underneath the cap is a switch for selecting the operating mode.
5.8.3

Setting the welding current and wire speed

Operating
element
40
The wire speed can be selected on the wire feed unit as an absolute value across the
entire setting range.
The wire speed is approximately specified by the welding machine control and can be
corrected as a percentage on the wire feed unit

MANUAL operating mode (outer scale):
The wire speed can be selected on the wire feed unit as an absolute
value across the entire setting range.
CORRECTION operating mode (inner scale):
The wire speed is specified largely by the welding machine control and
can be corrected as a percentage on the wire feed unit
