Start amp (TIG AC and DC)
Is adjusted from 3 A to the maximum welding current.
If the selected start amp is lower than 3 A, the start
amp will be 50% of the welding current. If the start
amp is higher than the maximum welding current the
start amp will be the same as the welding current.
Original setting: 50%
Stop amp (TIG AC and DC)
Can be adjusted from 3 A to the maximum welding
current. If the selected stop amp is higher than the
maximum welding current the stop amp will be similar
to the adjusted welding current.
Original setting: 3A
Pre-heat time (TIG-AC)
Can be adjusted from 0.1 to 2.55 Sec.
Original setting: 0.1 Sec.
Hot start time (MMA)
Can adjusted from 0.0 to 5.0 Sec.
The hot start current is 20% above the welding
current.
Original setting: 0.0 Sec.
Fixed functions
A number of functions are fixed and cannot be
connected or disconnected from the control panel.
- Anti-freeze
- Arc power
Antifreeze
The antifreeze function is always active. When
welding MMA or TIG it may occur that the electrode
sticks to the work piece. The machine will register
that the electrode sticks and it will then decrease the
welding current to 3 A which make it easy to break
the electrode off the work piece. Welding can then be
restarted as usual.
Arc Power
Arc power is a arc enhancing function used to
stabilize the arc in electrode welding. This is done by
increasing the welding current during the short
circuits. The additional current disappears when there
is no longer a short circuit. The function is optimized
to a large amount of rutile and basic electrodes.
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.
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.
