GENERAL NOTES

Before using this welding machine, carefully read the stan-
dards CEI 26/9 - CENELEC HD 407 and CEI 26.11 - CEN-
ELEC HD 433. Also make sure the insulation of the cables,
electrode clamps, sockets and plugs are intact, and that the
size and length of the welding cables are compatible with the
current used.
3.4 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 AC 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 simultaneous-
ly with the earth clamp.
- Turn the machine on using the switch AC.
- Select the MMA procedure by pressing the button A:
LED B 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.
If you wish to adjust the Hot-start (LED AM) and Arc force
functions (LED AN), see the previous paragraph.
3.5 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-
nector Y.
Connect the torch gas hose fitting to the fitting Z on the
machine, and the gas hose from the cylinder pressure regu-
lator to the gas fitting AD on the rear panel.

3.5.1 Cooling unit

If using a water-cooled torch, use the cooling unit.

3.5.1.1 Explanation of technical specifications

U1 Rated supply voltage
1x400V Single-phase power supply
50/60 Hz Frequency
I1max Maximum absorbed current
Pmax Maximum pressure
P (1l/min) Refrigerant power measured at 1L/min
3.5.1.2 Description of protections
- Coolant pressure protection
This protection is achieved by means of a pressure swit-
ch, inserted in the fluid delivery circuit, which controls a
microswitch.
- Fuse (T 2A/250V-Ø 5x20)
This fuse was inserted to protect the pump.
3.5.1.3 Installation
Unscrew the cap and fill the tank (the equipment is supplied
with approximately one liter of fluid).
It is important to periodically check, through the slot, that the
fluid remains at the "max" level.
As a coolant, use water (preferably deionized) mixed with
alcohol in percentages defined according to the following table:
temperature
0°C up to -5°C
-5°C up to -10°C
NOTE If the pump turns with no coolant present, you must
remove all air from the tubes.
If so, turn off the power source, disconnect the torche hoses,
fill the tank, connect a hose to the fitting (
other end of the hose in the tank. Start the power source for
approximately 10/15 seconds, then connect the torche
hoses.
