5.4.11 MIG/MAG program sequence ("Program steps" mode)
Certain materials, aluminium for example, require special functions for reliable and high-quality welding.
In this case, the special latched mode is used with the following programs:
• Start program P
START
(avoidance of cold welds at start of seam)
• Main program P
A
(constant welding)
• Reduced main program P
B
(targeted heat reduction)
• End program P
END
)
(avoidance of end-craters by targeted heat reduction)
The programs contain parameters such as wire feed speed (operating point), correction of arc length,
slope times, program duration, etc.
Figure 5-43
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.
