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.
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
WARNING
For any maintenance or repair operations it is
recommended to contact the nearest technical service
center or Lincoln Electric. Maintenance or repairs
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.
WARNING
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.
