MMA WELDING (MANUAL METAL ARC)
- This welding machine is suitable for welding all types of
electrodes, with the exception of cellulosic (AWS 6010)*.
- Make sure that the switch
S
is in position 0, then connect
the welding cables, observing the polarity required by the
manufacturer of the electrodes you will be using; also con-
nect the clamp of the ground cable to the workpiece, as
close to the weld as possible, making sure that there is good
electrical contact.
- Do NOT touch the torch or electrode clamp simultaneou-
sly with the earth clamp.
- Turn the machine on using the switch
S
.
- Select the MMA procedure by pressing the button

lit.
- Adjust the current based on the diameter of the electrode,
the welding position and the type of joint to be made.
- Always remember to shut off the machine and remove
the electrode from the clamp after welding.

TIG WELDING
This welding machine is suitable for welding stainless steel,
iron, or copper using the TIG procedure.
Connect the earth cable connector to the positive pole (+) of
the welding machine, and the clamp to the workpiece as
close as possible to the welding point, making sure there is

good electrical contact.
Connect the power connector of the TIG torch to the nega-
tive pole (-) of the welding machine.
Connect the torch connector to the welding machine con-

.
Connect the torch gas hose fitting to the fitting
O
on the
machine, and the gas hose from the cylinder pressure regu-
lator to the gas fitting
R
on the rear panel.
Turn on the machine.
Do not touch live parts and output terminals while the machi-
ne is powered.
The first time the machine is switched on, select the mode
using the button A and the welding current using the knob
H
.
The flow of inert gas must be set to a value (in liters per minu-
te) approximately 6 times the diameter of the electrode.
4 REMOTE CONTROLS
The following remote controls may be connected to adjust
the welding current for this welding machine:
Art. 193 Foot control (used in TIG welding)
Art (1266) TIG UP/DOWN Torch.
Art 1192+Art 187 (used in MMA welding)
ART. 1180 Connection to simultaneously connect the torch
and the pedal control.
ART. 193 may be used in any TIG welding mode with this
accessory.
Remote controls that include a potentiometer regulate
the welding current from the minimum to the maximum
current set via the knob H.
Remote controls with UP/DOWN logic regulate the wel-
ding current from the minimum to the maximum.
5 MAINTENANCE
Any maintenance operation must be carried out by qua-
lified personnel in compliance with standard CEI 26-29
(IEC 60974-4).
5.1 GENERATOR MAINTENANCE
In the case of maintenance inside the machine, make
sure that the switch
S
is in position "O"
and that the
power cord is disconnected from the mains.
It is also necessary to periodically clean the interior of the
machine from the accumulated metal dust, using com-
pressed air.
5.2
PRECAUTIONS AFTER REPAIRS.
After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secon-
dary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the origi-
nal machine, to prevent a connection from occurring
between the primary and secondary circuits should a wire
accidentally break or be disconnected.
Also mount the screws with geared washers as on the ori-
ginal machine.
