Connecting Gas; Operating The Machine - STAMOS Power2 S-ARC 160LT Manuel D'utilisation

4.3.2. CONNECTING GAS

• Gas tanks must be placed far from the welded object
and be protected against falling.
• The welding torch gas connector should be
connected to the cylinder or the gas installation by
a suitable hose and a with gas flow regulator. Please
note! Connection of line regulators to the tank and
the other way round is prohibited. Such a change can
result in regulator damage and serious injuries.
• Economical gas use extends the welding time.

6. CONNECTING LEADS
MMA WELDING MODE:
1. Connect the welding cable to the connector marked
with a "+" sign and twist the cable plug to secure the
connection.

2. Connect the ground cable to the connector marked
with a "-" sign and twist the cable plug to secure the
connection.
ATTENTION! Polarization of the leads has to be
different! All polarization information should be
shown on the packaging supplied by the electrode
manufacturer.
3. Now you can connect the power lead and turn the
power on, once the return lead is connected to the
welded element, you can start working.

LIFT TIG WELDING MODE
1. Connect the ground cable to the connector marked
with a "+" sign and twist the cable plug to secure the
connection.
2. Connect the welding cable to the connector marked
with a "-" sign and twist the cable plug to secure the
connection.
3. Connect the gas line from the burner to the
regulator/flow meter on the shielding gas cylinder.
4. Now you can connect the power lead and turn the
power on, once the return lead is connected to the

7. OPERATING THE MACHINE

1. After connecting the wires as described in the
manual, switch the power switch on the rear panel to
the "ON" position
2. Select the MMA/LIFT TIG welding mode.
• in the S-ARC 160LT model, use the [10] button
• in the S-ARC 160PFC and S-ARC 200PFC models, use
the [4] switch
• for S-ARC 320LT and S-ARC 400LT models, skip this
step (those models are not equipped with a mode
switch)
MMA mode
3. Set the amperage appropriate for the electrode
used.
4. Touch/tap/rub the end of the electrode against the
workpiece and quickly retract to the required arc
length.
5. The arc will extinguish as the electrode moves away
from the work area.
Lift TIG mode
3. After proper parameterization, open the gas cylinder
valve, the gas valve on the burner and adjust the
required gas flow rate.
4. The arc will ignite when the electrode is rubbed
against the workpiece and lifted by a distance of 2 to
4 mm.
5. The arc will extinguish as the electrode (torch) moves
away from the work area.
6. Before switching off the power, switch the machine
off using the ON/OFF button on the back of the
machine.
