5.3.3 Degaussing the workpiece before welding (degauss)
Figure 5-9
• Measure the magnetic flux density.
Figure 5-10
• Determine power cables with the corresponding number of turns according to table “Magnetic flux
density - adjustment aid”
> see 10.1 chapter
and lay them around the component accordin-
gly
> see 5.3.2 chapter
.
• Connect power cables to the power source (the polarity is freely selectable).
Figure 5-11
• Switch on the power source.
• Press the degaussing pushbutton.
• The signal light flashes.
The degaussing process is completed when the signal light degauss is on permanently.
Figure 5-12
• Measure the magnetic flux density.
• Compare the measured magnetic flux density with the table “Guide values for residual flux densi-
ty”
> see 10.2 chapter
for the corresponding welding process.
If the residual field strength is too high, the process of degaussing can be repeated as often as
desired (increase the number of turns if necessary).
