General Notes; Remote Controls; Tig Welding - Elettro ARC Manuel D'instructions

D8 LED – End current
It is adjustable with the D1 knob:
- In DC: 5-100% of the welding current,
- In AC: 10-100% of the welding current.
D9 LED
Post gas. Adjusts the gas flow time at the end of welding (0-30
sec.).
E1 and C6 LEDs – AC frequency
Adjust the AC frequency from 50 to 150Hz.
E4 and C5 LEDs – Wave balance.
Adjust the cleaning or the penetration.

3.3. 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 F is in OFF position, then connect
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 workpiece, as close to the
weld as possible, making sure that there is good electrical
contact.
- Do NOT touch the torch or electrode clamp simultaneously with
the earth clamp.
-Turn the machine on using the switch F.
- Select the MMA procedure by pressing the button B7: LED B10
lit.
- In MMA procedure the cooling fan is always on.
- 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.

3.5. TIG WELDING

This welding machine is suitable for welding stainless steel, iron,
or copper using the TIG procedure in DC mode and aluminium,
brass and magnesium using the TIG procedure in AC mode.
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 welding machine connector
C.
Connect the torch gas hose fitting to the fitting B on the machine,
and the gas hose from the cylinder pressure regulator to the gas
fitting E on the rear panel.
Turn on the machine by means of the switch F.
Do not touch live parts and output terminals while the machine
is powered.
Select the mode using the push-buttons B1 and B4 and the
welding parameters by means of the knob D1 as described in
paragraph 3.2.
In TIG procedure, the cooling fan is timed.
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 litters 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.
