General Notes; Tig Welding - Elettro TIG 2210AC/DC Betriebsanleitung

It lights when the operator exceeds the duty cycle or
percentage intermittence allowed for the machine and
simultaneously locks the current output.
N.B. Under this condition the fan goes on cooling the
power source.
T – Display
Displays the welding current and the settings which were
selected via the G push-button and adjusted via the R knob.
Y – Selector switch for programs in memory.
Selects and saves the programs in memory.
The welding machine can save nine welding programs
P01.....P09 and call them up via this button. A working
program PL is also available.
Selecting
When this push-button is pressed briefly, the T display shows
the program number next to the one in use. If this has not
been saved, the message will flash, otherwise it remains
steady.
Saving
Once the program has been selected, hold down for more
than 3 seconds to save the data in memory.
To confirm this, the program number on the T display will
stop flashing
A7 – 10-PIN CONNECTOR.
The following remote controls are to be connected to this
connector:
a) foot control
b) torch with start button
c) torch with potentiometer
d) torch with up/down
e) remote control, etc.
P – ¼ gas fitting.
This is where the gas hose of the TIG welding torch is to be
connected.
Q

A8
Positive output terminal (+)
B1 – Switch.
Turns the machine on and off.
B2 – Gas intake fitting.
A9 – Power supply cable.

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.
WARNING: This equipment does not comply with IEC
61000-3-12. If it is connected to a public low voltage
system, it is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution
network operator if necessary, that the equipment may be
connected.
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 B1 is in position 0, 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 B1.
- Select the MMA procedure by pressing the button C:
LED A lit.
- 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 A7.
Connect the torch gas hose fitting to the fitting P on the
machine, and the gas hose from the cylinder pressure
regulator to the gas fitting B2 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, X and A3 and the welding
parameters by means of the key G and the knob R as
described in paragraph 3.2 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,
