• Measure the magnetic flux density.
• Compare the measured magnetic flux density with the table “Guide values for residual flux den-
sity”
> see 11.2 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).
5.6.3.1 Automatic cut-out
The demagnetization process is stopped within 5 seconds if no current flow can be established.
The display shows the message
(interruption). Check all circuit connections and repeat the
process.
5.6.4 Decommissioning
Figure 5-28
• Switch off machine at the main switch.
• Remove all connections.
5.7 Remote control
Remote controls are used for the remote operation of various machine functions. The 2-pin remote con-
trol connection is installed on the device controller
> see 4.3 chapter
.
5.8 Arc length restriction (USP)
The arc length restriction
function stops the welding process when an excessive arc voltage is detec-
ted (unusually high gap between electrode and workpiece). This function can be adjusted in the corres-
ponding Expert menu, depending on the process:
MMA welding
> see 5.4.7 chapter
TIG welding
> see 5.5.8 chapter
The arc length restriction cannot be used for cel characteristics (if available).
