P - Negative output terminal (-)
Q -Positive output terminal (+)
S - switch
Turns the machine on and off
R - gas intake fitting
3.3 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
connect 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 simultaneously
with the earth clamp.
- Turn the machine on using the switch S.
- Select the MMA procedure by pressing the button A:
LED F 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.
3.4 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
negative pole (-) of the welding machine.
Connect the torch connector to the welding machine
connector I.
Connect the torch gas hose fitting to the fitting O on the
machine, and the gas hose from the cylinder pressure
regulator to the gas fitting R on the rear panel.
Turn on the machine.
Do not touch live parts and output terminals while the
machine is powered.
The first time the machine is switched on, select the mode
using the button A and the welding current using the knob
10
H. The flow of inert gas must be set to a value (in liters
per minute) 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
welding current from the minimum to the maximum.
5 MAINTENANCE
Any maintenance operation must be carried out by
qualified personnel in compliance with standard IEC
60974-4.
5.1 GENERATOR MAINTENANCE
In the case of maintenance inside the machine, make sure
that the switch P 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
compressed 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
secondary 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 original 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
original machine.
