MIG/MAG program sequence ("Program steps" mode)
Certain materials, such as aluminium, require special functions in order to be able to weld them safely
and at high quality. The latched special operating mode is used here with the following programs:
• Start program P
START
(reduction of cool points at the start of the seam)
• Main program P
A
(continuous welding)
• Reduced main program P
B
(targeted heat reduction)
• End program P
END)
(minimisation of end craters via targeted heat reduction)
The programs include the parameters wire speed (operating point), arc length correction, slope times,
program duration, etc.
Figure 5-41
In every JOB, separate settings can be made for the ignition program, reduced main program and end
program as to whether or not to alternate with the pulse process.
These properties are stored on the welding machine with the JOB. This means that in the factory settings,
the pulse process is active during the end program in all forceArc JOBs.
To activate or set the function
