POWER SUPPLY CONNECTION

Before connecting the machine, check the
voltage, number of phases and power fre-
quency. The admissible power supply voltage
is reported in the "Technical Specifications"
section of this manual and on the machine's
rating label. Check that the welding machine
is correctly connected to the ground. Also
check that the plug supplied with the machine
is compatible with the local mains power out-
let. Make sure there is sufficient power to run
the machine. The "Technical Specifications"
section of this manual contains information on
the type of line protection devices to use. The
machine comes with a specific power cord (28
of Figure 2) which should not be extended. If
an extension cord is necessary, use one that
has the same or a larger cross-section than
the machine's power cord depending on the
length of the cord.
Use a "+" bipolar ground cable with a
cross-section equal to or greater than
1.5 mm² for the TT162 machine and 2.5
mm² for the TT168 and TT 205 machines.
4. OUTPUT CONNECTIONS
The welding cables are connected with
quick coupling systems that use special
connectors.
4.1 CONNECTION FOR MMA WELDING
1) Connect the cable of the electrode
holder to the special "+" connector posi-
tioned on the front of the machine (22 of
Fig 2). Align the key with the slot and
tighten by turning in a clockwise direc-
tion until it stops. Do not over tighten!
2) Connect the ground cable to the "-"
connector positioned on the front of the
machine (21 of Fig 2). Align the key with
the slot and tighten by turning in a clock-
wise direction until it stops. Do not over
tighten! The machine is supplied with the
polarities configured for MMA welding.
Attention: Some types of electrodes
require the negative polarity on the elec-
trode holder and the positive polarity on
the ground cable. In this case, invert the
external connection. Always check the
packaging of the electrodes for the cor-
rect polarity!

4.2 CONNECTION FOR TIG WELDING
1) Connect the ground cable to the
appropriate "+" connector positioned on
the front of the machine (22 of Fig 2).
Align the key with the slot to insert and
tighten by turning in a clockwise direc-
tion until it stops. Do not over tighten!
2) Connect the torch to the "–" connector
positioned on the front of the machine
(21 of Fig. 2). Align the key with the slot
to insert and tighten by turning in a
clockwise direction until it stops. Do not
over tighten!
3) Connect the connector of the welding
torch signal to the appropriate socket (23
of Fig. 2) positioned on the front of the
welding machine. Turn in a clockwise
direction until it blocks. Do not over tight-
en!
5. CONNECTION
CYLINDER AND REGULATOR
Only for TIG welding. In case of MMA
welding, skip this whole section. Before
connecting the gas cylinder, first check
that the cylinder contains pure Argon
gas. Always use
equipped with a torch button.
Carefully follow the procedure below as
shown in Figure 3:
1. Connect the pressure gauge (2) to the
cylinder (3). Secure the connecting nut
(6) of the gauge (2) to the cylinder (3).
Do not over tighten because too much
pressure may damage the valve (1) of
the cylinder.
2. Connect the gas hose (4) to the gauge
(2), securing it with a tube clamp (5)
(alternatively, equip the cylinder and
hose with quick connectors).
3. Connect the other end of the hose to
the special connection positioned on the
back of the welding machine (26 of Fig.
2) and secure with a tube clamp.
4. Connect the gas hose of the torch to
the connector positioned on the front of
the welding machine (24 of Fig. 1). Turn
in a clockwise direction. Do not over
tighten!
3. Open the valve (1) of the cylinder (3).
Press the torch button and make sure the
gas flows correctly.
