Definition of MIG/MAG welding tasks
This machine range features simple operation with a very wide range of functions.
• JOBs (welding tasks consisting of welding process, type of material, wire diameter and type of
shielding gas) are pre-defined for all common welding tasks.
• Simple JOB selection from a list of pre-defined JOBs (sticker on the machine).
• The required process parameters are calculated by the system depending on the operating point
specified (single-dial operation via wire speed rotary dial).
• Conventional welding task definition using wire speed and welding voltage is also possible.
The welding task definition described below applies when defining MIG/MAG and cored wire
welding tasks.
Pay attention to the signal light for the polarity setting!
It may be necessary to change the welding current polarity depending on the JOB selected or the
welding process.
• Reconnect the polarity selction plug if necessary.
5.7.7
Welding task selection
The settings for the respective welding parameters are defined by the different JOBs. The right JOB can
be determined quickly with the JOB list .
5.7.7.1 JOB selection
• Select JOB (welding task) by means of the JOB list.
The "JOB list" sticker is on the inside of the cover of the wire feed unit.
• Set the operating point by means of the panel thickness- See 5.7.8 MIG/MAG operating point chapter.
It is only possible to change the JOB number when no welding current is flowing.
