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
Y.
Connect the torch gas hose fitting to the fitting X on the machine,
and the gas hose from the cylinder pressure regulator to the gas
fitting A4 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-buttons C and V and the welding parameters by means
of the key I and the knob P as described in paragraph 3.2.
In TIG procedure the cooling fan starts working, after 5 seconds
it stops for starting again to work during welding process till the
machine is cooled.
The flow of inert gas must be set to a value (in liters per minute)
approximately 6 times the diameter of the electrode.
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 x 10= 16
It./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 W 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 working current is
displayed. Follow the instructions in paragraphs 3.2 and 3.5,
then proceed as follows to save the data in the program P01:
- Briefly press the push-button W the message P01 will
appear flashing.
- Press push-button W 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 W as many times
as necessary to display the desired program. P01 will be
displayed the next rime the machine is turned on.
PRESSING THE W 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 W briefly and select the desired
program number.
- The symbol of free programs is flashing.
- Press the push buttons C and V and select the welding
procedure and mode (paragraph 3.1).
- Turn the knob P and set the welding current.
If the TIG procedure has been selected, activate the LED O
(post gas) by means of the push-button I, and set the desired
value via the knob P (paragraph 3.1.)
If you wish to adjust the "slope" times or other parameters,
after making these adjustments which are necessary in
order to weld, follow the steps described in paragraph 3.1.
Weld, even briefly, and decide where to save.
To save in the previously selected program, press the button
W for more than 3 seconds, until the number stops flashing.
To save in a different program, make your selection by briefly
pressing the push-button W, then hold down the push button
W for more than 3 seconds.
3.6.3 Save from a saved program
Beginning with a previously saved program, the operator
may edit the data in memory to update the program itself, or
to find new parameters to save in another program.
3.6.3.1 Update
- Alter turning on the machine, select the parameters to
be edited and edit them.
- Weld, even briefly.
- Hold down the W button for more than 3 seconds, until
the save is confirmed (program symbol changes from
flashing to steady).
3.6.3.2 Save in a new program
- After turning on the machine, select the parameters to
be edited and edit them.
- Weld, even briefly.
- Briefly press the selector W until the desired program is
displayed.
- Hold down the W button until the save is confirmed
(program symbol changes from flashing to steady).

4. REMOTE CONTROLS

The following remote controls may be connected to adjust
the welding current for this welding machine:
Item 570008 Foot control (used in TIG welding)
Item 535805 TIG UP/DOWN Torch.
Item 530330+ltem 570006 (used in MMA welding)
Item 363307 Connection to simultaneously connect the torch
and the pedal control.
Item 570008 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 P.
Remote controls with UP/DOWN Iogic regulate the
welding current from the minimum to the maximum.
The remote control settings are always active in the PL
program, while they are not active in a saved program.
