GENERAL NOTES

Before using this welding machine, carefully read the
standards CEI 26/9 - CENELEC HD 407 and CEI 26.11 -
CENELEC 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 con-

nect 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 work-
piece, as close to the weld as possible, making sure that
there is good electrical contact. 
- Do NOT touch the torch or electrode clamp simultane-
ously 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 elec-
trode, 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 neg-
ative pole (-) of the welding machine.
Connect the torch connector to the welding machine
connector 

Y

.

Connect the torch gas hose fitting to the fitting 

Z

on the

machine, and the gas hose from the cylinder pressure
regulator to the gas fitting 

AD

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 turned on, select the mode
using the push-button 

A

and the welding parameters by

means of the key 

R

and the knob 

O

as described in para-

graph 3.2.
The flow of inert gas must be set to a value (in liters per
minute) approximately 6 times the diameter of the elec-
trode.
If you are using gas-lens type accessories, the gas
throughput may be reduced to approximately 3 times the

diameter of the electrode. The diameter of the ceramic
nozzle must be 4 to 6 times the diameter of the electrode.
The most commonly used gas is normally ARGON,
because it is less costly than other inert gases, but you
may also use blends of ARGON with a maximum of 2%
HYDROGEN for welding stainless steel, and HELIUM or
ARGON-HELIUM blends for welding copper. These
blends increase the heat of the arc while welding, but are
much more expensive.
If you are using HELIUM gas, increase the liters per
minute to 10 times the diameter of the electrode (Ex.
diameter 1.6 x10= 16 lt./min of Helium).
Use D.I.N. 10 protective glasses for up to 75A, and D.I.N.
11 from 75A up.

3.6.

SAVING

You may save parameters only after welding.
Pressing the push-button Q briefly makes a selection;
held down for more than 3 seconds, it saves the data.
Each time it is turned on, the machine always shows
the last welding condition used.

3.6.1.

Saving data from the PL program

Using the machine for the first time

When the machine is turned on, the display shows the
symbol 

PL

; this disappears after 5 seconds, and a work-

ing current is displayed. Follow the instructions in para-
graphs 3.2 and 3.5, then proceed as follows to save the
data in the program 

P01

:

· Briefly press the push-button 

Q

(mem+mem-) the mes-

sage 

P01

will appear flashing.

· Press push-button 

Q

for more than 3 seconds, until the

symbol 

P01

stops flashing: at this point, the data have

been saved.
· Obviously, if you wish to save in a program other than

P01

, you should briefly press the push-button 

Q

as many

times as necessary to display the desired program. 

P01

will be displayed the next time the machine is turned on.

PRESSING THE Q PUSH-BUTTON BRIEFLY MAKES A
SELECTION, WHILE HOLDING IT DOWN FOR MORE
THAN 3 SECONDS SAVES THE DATA.

3.6.2.

Save from a free program

The operator may edit and save a selected program by
proceeding as follows:
· Press the push-button 

Q

briefly and select the desired

program number.

· The symbol of free programs is flashing.

· Press the push-button 

A

and select the welding proce-

dure and mode (paragraph 3.1).
· Turn the knob 

O

and set the welding current.

· If the TIG procedure has been selected, activate the LED

(post gas) by means of the push-button 

R

, and set the

desired value via the knob 

O

(paragraph 3.1.)

· If you wish to adjust the "slope" times or other parame-
ters, after making these adjustments which are 

neces-

sary in order to weld

, follow the steps described in para-

graph 3.1.

· Weld, even briefly, and decide where to save

· To save in the previously selected program, press the
button 

Q

for more than 3 seconds, until the number stops

flashing.
