Filler wire welding

4.3.1

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:
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.
Read and observe the documentation to all system and accessory components!
4.3.1.1

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 4.3.1.2 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 .
4.3.1.2

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.

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
