VRD LED's (enabled on Australian Machines only): This
machine is provided by VRD (Voltage Reduction Device)
function: this reduces the voltage at the output leads.
The VRD function is enabled by factory default only
on machines that meet the AS 1674.2 Australian
Standards. (C-Tick logo " " on/near the Rating Plate
applied on the machine).
The VRD LED is ON when the Output Voltage is below
12V with the Machine at idle (no welding time).
For others machines this function is disabled (the LED is
always OFF).
Welding Mode Switch: With four positions, controls the
welding mode of the machine: three for Stick welding
(Soft, Crisp and User defined) and one for Lift TIG
welding.
•
Soft Stick: For a welding with a low spatter
presence. The Auto Adaptive Arc Force is enabled.
•
Crisp Stick: For an aggressive welding, with an
increased Arc stability. The Auto Adaptive Arc
Force is enabled.
•
User defined MMA parameters: with this
welding mode the Auto Adaptive Arc Force is
disabled. This welding mode allows to manually
adjust the Hot Start and the Arc Force as following:
Hot Start: The Output Current initial increment
is adjustable between 0 and 60% of the current set
through the Output Current Knob.
Arc Force: The Output Current temporary
increments are adjustable between 0 and 50% of
the current set through the Output Current Knob.
•
Lift TIG: When the mode switch is in the Lift
TIG position, the stick welding functions are
disabled and the machine is ready for Lift TIG
welding. Lift TIG is a method of starting a TIG weld
by first pressing the TIG torch electrode on the work
piece in order to create a low current short circuit.
Then, the electrode is lifted from the work piece to
start the TIG arc.
Meter: The meter displays the preset welding current
before welding and the actual welding current during
welding.
Through the Pushbutton on the Display right side, the
Display alternatively shown the output Current (A) or
Voltage (V). The LEDs (A) (V) on top side indicates the
measure unit of the value shown by the Display.
English
A flashing dot on the Display indicates that the value
read is the average value (V or A) of the previous
welding time. This feature shown the average value for
5seconds after every welding time.
Other Controls and
Features
A. Power Switch: It turns ON /
OFF the input power to the
machine.
B. Input cable: Connect it to
the mains.
C. Fan: This machine has a
F.A.N. (Fan As Needed)
circuitry inside: the fan is
automatically turned ON or
OFF. This feature reduces
the amount of dirt which can be drawn inside the
machine and reduces power consumption. When
the machine is turned ON the fan will turn ON. The
fan will continue to run whenever the machine is
welding. If the machine doesn't weld for more than
five minutes, the fan will turn OFF.
Maintenance
For any maintenance or repair operations it is
recommended to contact the nearest technical service
center or Lincoln Electric.
performed by unauthorized service centers or personnel
will null and void the manufacturers warranty.
The frequency of the maintenance operations may vary
in accordance with the working environment. Any
noticeable damage should be reported immediately.
•
Check cables and connections integrity. Replace, if
necessary.
•
Keep clean the machine. Use a soft dry cloth to
clean the external case, especially the airflow inlet /
outlet louvers.
Do not open this machine and do not introduce anything
into its openings. Power supply must be disconnected
from the machine before each maintenance and service.
After each repair, perform proper tests to ensure safety.
