System Presentation; General - Selco Genesis 302 AC/DC Manuel D'instructions

Connection for TIG welding
- Connect the gas hose (1) from the cylinder to the rear gas
connection.
- Connect the TIG torch to the central adapter (2), ensuring that
the fastening ring is fully tightened.
- Connect the red colored
inlet quick connector of the cooling unit (3).
- Connect the blue colored
outlet quick connector of the cooling unit (4).

4 SYSTEM PRESENTATION

4.1 General

The Genesis 302 AC/DC - Genesis 382 AC/DC are constant cur-
rent inverter power sources developed for electrode (MMA), TIG
DC (direct current) and TIG AC (alternating current) welding.
3.2 Front control panel
1 Power supply
Indicates that the equipment is connected to the mains
and is on.
2 General alarm
Indicates the possible intervention of protection devices
such as the temperature protection.
3 Power on
Indicates the presence of voltage on the equipment
outlet connections.
4 7-segment display
Allows the general welding machine parameters to be
displayed during start-up, settings, current and voltage
readings, while welding, and encoding of the alarms.

5 Main adjustment handle
Allows the welding current to be continuously adjusted.
Allows adjustment of the selected parameter on graph 6.
The value is shown on display 4.
6 Welding parameters
The graph on the panel allows the selection and adjust-
ment of the welding parameters.
Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 6A, Maximum Imax, Default 100A
Slope-up
Allows you to set a gradual passage between the initial
current and the welding current. Parameter set in sec-
onds (s).
Minimum 0.0s, Maximum 10.0s, Default 0.0s
Bilevel current
Permits adjustment of the secondary current in the
bilevel welding mode.
On first pressing the torch button, the pre-gas starts,
the arc strikes and the initial current will be used when
welding.
On first releasing it, the raising ramp of the welding current
"I1" occurs. If the welder now presses and releases the
button quickly, "I2" can be used; by pressing and releasing
it quickly again, "I1" is used again, and so on.
If you press the button for a longer time, the lowering ramp
for the current starts, thus reaching the final current.
By releasing the button again, the arc goes out and the
gas continues to flow for the post-gas stage.
Parameter setting: Amperes (A).
Minimum 6A, Maximum Imax, Default 50A
Basic current
Permits adjustment of the basic current in pulsed and
fast pulse modes.
Parameter set in Amps (A).
Minimum 6A-1%, Maximum Weld current-100%,
Default 50%
Peak time
Permits adjustment of the peak time during pulse and
fast pulse operation.
Parameter setting: seconds (s).
Minimum 0.02s, Maximum 2.00s, Default 0.24s
Background time
Permits adjustment of the background current time dur-
ing pulse and fast pulse operation.
Parameter setting: seconds (s).
Minimum 0.02s, Maximum 2.00s, Default 0.24s
Fast Pulse frequency
Allows regulation of the pulse frequency.
Allows focusing action and better stability of the electric
arc to be obtained.
Parameter setting: Hertz (Hz).
Minimum 20Hz, Maximum 500Hz, Default 100Hz
