4.0 MACHINE DESCRIPTION

These constant current inverter power sources are able to per-
form the following types of welding with excellent results:
- MMA (see 9.1);
- TIG (with reduction in the current on short-circuiting, see 9.2);
In inverter welders, the output current is unaffected by va-
riations in the supply voltage and the length of the arc, and is
perfectly levelled, giving the best welding quality.
The generator is equipped with:
- positive (+) and negative (-) socket;,
- front panel,
- rear control panel
The Genesis models 282-352 TLE also feature:
- a socket for connection of the torch button wires
- a socket for the torch gas fitting

*
L1 : Voltage warning light green led.
Comes on with the start switch (Fig.3) "I1" in position "I" and
indicates that the plant is on and there is voltage.
*
L2 : Safety device warning light yellow led.
lndicates that the safety devices like thermal cut out, mains
overvoltage and undervoltage are activated (it turns on when
the mains voltage is out of the limits indicated in ch. 6.1 and
can jeopardize the electronic components).
With "L2" on, the power source remains connected to the
mains but does not deliver power at the output and an alarm
message will appear on "D".
"L2" remains on until the fault has been removed and in any
case until the inner temperatures or the tension are not within
the normal values (in this case it is necessary to leave the
power source on to exploit the operating ventilator and redu-
ce the time when it is not active).
Press any key to reset the alarm. If the alarm has not been elimi-
nated the display after the initial reset will show the error again.
* L3: pilot light indicating power at output.
Indicates the presence of output voltage, it is always lit in
MMA welding while in TIG welding it is sensitive to the wel-
ding cycles.
* C: Connector.
This is the socket used by all the remote controls for MMA
and TIG welding.
It is activated through selection on the keyboard; in the case that
no appliance is activated, the current will be maintained 6A.
* D: liquid crystal alphanumerical display.
It displays the set welding parameters.

* T1: Key selects the type of welding.
TIG welding and MMA welding
* T2: Key selects the welding current control.
Control from keyboard
* T3: Key allows you to select and change the welding para-
meters.
In the MMA process it allows you to switch between two dif-
ferent parameter setup modes (automatic, to select the type
of electrode and diameter, or manual).
* T4: Measurement key.
Allows you to view the metered welding current and voltage.
* T5: UP/DOWN keys.
keys for increasing and decreasing the data shown on the di-
splay. In MMA welding they allow the diameter of the selec-
ted electrode to increase or decrease, as well as selecting the
preset type of electrode.
* Switching on the machine.
When the machine is switched on, the display shows infor-
mation about the model and the software version installed.
After a few seconds, the machine is operating in the same
conditions as it was when it was last switched off.
At any time, you can:
- press key T1 to enable the required welding process.
- press key T2 to select welding current setting via keyboard
or remote control.
* Setting the MMA welding parameters.
MMA welding can be set in two different ways:
1) Setting of the electrode type and diameter with automatic
calculation of welding parameter
2) Manual setting of welding current, HOT-START and ARC-
FORCE.
To change from one enabling mode to the other press the
"SET" key for about 4 seconds.
* Manual setting.
Press the SET key to select the welding parameters successi-
vely.
Press keys T5 to increase to decrease the selected parameter.
* Automatic setting.
Press the SET key to change the selection mode from diame-
ters to type of electrode.
Press keys T5 to display the required item in the preselected
field, marked by square brackets.
