8 Arc force
Allows adjustment of the Arc force value in MMA.
Permits an adjustable energetic dynamic response in
welding, facilitating the welder's operations.
Increasing the value of the arc force to reduce the risks
of sticking of the electrode.
Parameter set as a percentage (%) of the welding current.
Minimum Off, Maximum 500%, Default 30%
204 Dynamic power control (DPC)
It enables the desired V/I characteristic to be selected.
I = C Constant current
The increase or reduction in arc length has no effect on
the welding current required.
Basic, Rutile, Acid, Steel, Cast iron
1÷ 20* Falling characteristic with adjustable slope
The increase in arc length causes a reduction in welding
current (and vice versa) according to the value imposed
by 1 to 20 amps per volt.
Cellulose, Aluminium
P = C* Constant power
The increase in arc length causes a reduction in the
welding current (and vice versa) according to the law:
V.I = K.
Cellulose, Aluminium
205 MMA Synergy
Allows you to set the best arc dynamics, selecting the
type of electrode used:
1 Standard (Basic/Rutile)
2 Cellulose
3 Steel
4 Aluminium
5 Cast iron
Default standard (1)
Selecting the correct arc dynamics enables maximum
benefit to be derived from the power source to achieve
the best possible welding performances.
Perfect weldability of the electrode used is not guaran-
teed (weldability depends on the quality of the consum-
ables and their preservation, the operating and welding
conditions, the numerous possible applications, etc.).
312 Arc detachment voltage
Allows you to set the voltage value at which the electric
arc switch-off is forced.
It permits improved management of the various operating
conditions that occur. In the spot welding phase, for exam-
ple, a low arc detachment voltage reduces re-striking of
the arc when moving the electrode away from the piece,
reducing spatter, burning and oxidisation of the piece.
If using electrodes that require high voltages, you are
advised to set a high threshold to prevent arc extinction
during welding.
Never set an arc detachment voltage higher than
the no-load voltage of the power source.
Parameter set in Volts (V).
Minimum 0V, Maximum 99.9V, Default 57V

551 Lock/unlock
Allows the locking of the panel controls and the inser-
tion of a protection code (consult the "Lock/unlock"
section).
601 Regulation step
Allows the regulation of a parameter with a step that can
be personalised by the operator.
Minimum 1, Maximum Imax, Default 1
602 External parameter CH1
Allows the management of external parameter 1 (mini-
mum value).
603 External parameter CH1
Allows the management of external parameter 1 (maxi-
mum value).
751 Current reading
Allow the real value of the welding current to be dis-
played.
Allows the welding current display method to be set.
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
Allows the welding voltage display method to be set.
852 TIG DC LIFT START enabling
On=Active, Off=No active
3.3.2 List of set up parameters (MIG/MAG)
(URANOS...Classic)
0 Save and quit
Allows you to save the changes and exit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
3 Wire speed
Allows the regulation of the wire feed rate.
Minimum 0.5 m/min, Maximum 22 m/min, Default
1.0m/min
7 Voltage
Allows the regulation of the arc voltage.
Allows regulation of the arc length during welding.
High voltage = long arc
Low voltage = short arc
Minimum 5V, Maximum 55.5V
10 Pre-gas
Allows you to set and adjust the gas flow prior to striking
of the arc.
Permits filling of the torch with gas and preparation of
the environment for welding.
Minimum off, Maximum 25 sec., Default 0.1 sec.
11 Soft start
Permits adjustment of the wire feed speed in the phases
prior to arc striking.
Given as a % of the wire speed set.
Permits striking at reduced speed, therefore softer and
with less spatter.
Minimum 10%, Maximum 100%, Default 50% (syn)
12 Motor slope
Allows you to set a gradual transition between the
sparking wire speed and the welding wire speed.
Minimum off, Maximum 1.0 sec., Default off
