3.8. 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 connector S3 on the welding
machine
Connect the torch gas hose fitting to the fitting S5 on the
machine, and the gas hose from the cylinder pressure regulator
to the gas fitting S11 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 and the
welding parameters 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 litres 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 litres 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.

3.9. SAVING A PROGRAM

IT IS POSSIBLE TO SAVE A PROGRAM ONLY AFTER
WELDING. THE PROGRAM ON START-UP IS ALWAYS THE
SAME AS THE ONE WHEN THE MACHINE WAS LAST
TURNED OFF.
3.9.1. Saving data
To save a program, first set the parameters of the process, the
method and the welding options, and perform a welding process,
even a short one. Using encoder S1, select the icon (fig. 3 ref. A)
and access the menu. Turn the encoder to select the icon
then turn it again and press it to choose and select the line to be
saved. Select the icon
program. Turn encoder S1 to select numbers or letters and then
select the icon to confirm.
3.9.2. Cancelling data
Using encoder S1, select the icon (fig. 3 ref. A) and access the
menu. Turn the encoder to select the icon
and press it to choose and select the line to be cancelled. After
selecting the program to be cancelled, turn the encoder to select
the icon .
3.9.3. Updating
It is possible to modify previously saved programs by saving
them in the same place or in a new one.
and enter the name to be given to the
, then turn it again
3.10. COOLING UNIT (optional only for item 168).
When using a water-cooled torch, use the cooling unit.
Plug the power cable of the cooling unit into the socket S10
of the welding machine and then insert the metallic three-
pole connector of the cooling unit in the connector S12 of the
welding machine. If no cooling unit is available, attach the
connector supplied to simulate the presence of the unit. If
this connector is not attached, or there is insufficient coolant,
the welding machine is disabled and the icon
on the display.
Caution! If electrode welding is selected, cooling is not
active and cannot be selected.

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 encoder S1.
Remote controls with UP/DOWN logic regulate the
welding current from the minimum to the maximum.
