Usage of the machine
When welding with PILOT 161 AC/DC machines a
heating of various components of the machine takes
place and during breaks these components will cool
down again.
It is not possible to overload the machine in normal
use, and there is no need for cooling down periods at
current settings up to e.g. 65 Amps. When the
machine is set for welding currents higher than these,
there will be a need for periods during which the
machine can cool down.
The length of these periods depends on the current
setting, and the machine should not be switched off
in the meantime. If the periods for cooling down
during use of the machine are not sufficiently long,
the overheating protection will automatically stop the
welding process and the yellow LED will come on.
The yellow LED switches off when the machine has
cooled down sufficiently, and the machine is ready for
welding. Max. load is:
TIG-welding
PILOT 161 AC/DC
100% max. load
65 A
60% max. load
80 A
60 % max. load when MMA welding means that a
cooling period of 4 minutes after welding for 6 mi-
nutes is required at a current setting of 80 Amps on a
PILOT 161 AC/DC; 10 minutes between start of each
welding period must be calculated in connection with
the above table.
LOCATIONS OF ERRORS
Attempts to locate errors should only be made by
trained experts.
The machine does not work and/or the display does
not light:
Check that mains fuse has not been damaged and
that mains supply is switched on. Replace fuse
and/or switch on supply if necessary
Mains error:
Occurs if there is too low or too high voltage on the
supply mains.
Ensure that mains fuse and supply are as specified.
Overheat:
Occurs if the machine is overloaded. This occurs
when welding with higher load than permitted, or if
the machine needs cleaning.
Ensure machine data or clean modules with clean,
dry, compressed air through the cooling ducts.
When the error has been corrected, the machine
should be switched off and then started again to
remove error indication.
MAINTENANCE
The PILOT welding machines require virtually no
maintenance. However, exposure to extremely dusty,
damp or corrosive air is damaging to welding
machines.
In order to prevent problems arising, the following
procedure should be observed at least once a year.
-
open the machine and clean it with clean, dry,
compressed air
Lack of maintenance can lead to reduced reliability
and cancellation of the guarantee.
