Connection for TIG welding
- Separately connect the torch gas pipe connector to the gas
distribution.
The protection gas flow is adjusted using the tap
normally located on the torch.
3 SYSTEM PRESENTATION
3.1 Generalities
These constant current inverter power sources are able to per-
form the following types of welding with excellent results:
- MMA,
- TIG (with reduction in the current on short-circuiting for
URANOS 1500).
In inverter welders, the output current is unaffected by va-ria-
tions 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.

Comes on as soon as the power source is powe-red.

Indicates cut-in of any protection devices such as the
thermal protection.
3 Potentiometer for setting the welding current
Allows you to continuously adjust the current both in
TIG and in MMA welding. This current stays unchanged
when the supply and welding conditions vary within the
allowed ranges.
In MMA welding, the presence of HOT-START and
ARC- FORCE means that the average output current
may be higher than that set.
4 MMA/TIG selection switch
With the lever down: it is in electrode welding (MMA)
mode, and thus the HOT-START, ARC-FORCE and
ANTI-STICKING are automatically activated.
With the lever up: it is in the mode for welding with
non-consumable tungsten electrode in an inert atmos-
phere (TIG). The MMA functions are removed, and the
LIFT start is activated.
5 4-pole military standard connector
For connection of the remote controls RC18.
3.3 Rear panel
1 Power supply cable
Connects the system to the mains.
2 Off/On switch
Turns on the electric power to the welder.
It has two positions, "O" off, and "I" on.
