3.5 TIG WELDING
This welding machine is suitable for welding stainless
ir on, or copper using the TIG procedure. Connect the earth
cable connector to the positive pole (+) of the welding
m achine, 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 Y.
Connect the torch gas hose fitting to the fitting X on the
machine, and the gas hose
regulator to the gas fitting A4 on the rear panel.
Turn on the m achine.
Do not touch live parts and output terminals while the
machine is powered.
The first rime the machine is turned on, selec
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 The flo w 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 mus t 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-HELIU
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 gla sses for up to 75A, and D.I.N. 11
from 75A up.
3.6 SAVING
You may save parameters only after welding.
P ressing the push-button W briefly makes a selection;
held down for more than 3 seconds, it saves the data.
E
ach 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
s ymbol PL; this disappears after 5 seconds, and a working
current is displayed. Follow the instructions
and 3.5, then proceed as follows to s
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 sto
ps flashing: at this point, the data have been
saved.
• Obviously, if yo u 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.

3.6.2. Save from a free program
T he 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 b uttons 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 sel

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 wh
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 p reviously selected program, press the
button W for more than 3 seconds, until the numbe

• To save in a different program, make your selection by
briefly pre ssing the push-button W, then hold down the
push button W for more than 3 seconds.
3.6.3 Save from a saved program
B eginning with a previously saved program, the operator
may edit the data in memory to upda
or to find new parameters to save in another program.
3.6.3.1 Update
• Alter turning on the machine,
be edited and edi t them.
• Weld, even briefly.
• Hold down the W button
the save is confirme d (program symbol changes from
flashing to steady).
3.6.3.2 Save in a n ew program
• After turning on the machine,
be edited and edit them.
• Weld, even briefly.
• Briefly press the selecto
displayed.
• Hold down the W button until the save is confirmed
(program sy mbol changes from flashing to steady).
