List of set up parameters (MMA)
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 Hot start
Allows adjustment of the hot start value in MMA.
Permits an adjustable hot start in the arc striking phases,
facilitating the start operations.
Parameter set as a percentage (%) of the welding current.
Minimum Off, Maximum 500%, Default std 80%,
Default cls 150%
7 Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 5A, Maximum Imax, Default 100A
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 std 30%,
Default cls 350%
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
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 oper-
ating conditions that occur. In the spot welding phase,
for example, a low arc detachment voltage reduces
re-striking of the arc when moving the electrode away
from the piece, reducing spatter, burning and oxidisa-
tion of the piece.
42
If using electrodes that require high voltages, you are
advised to set a high threshold to prevent arc extinction
during welding.
Parameter set in Volts (V).
Minimum 0V, Maximum 60V, Default std 57V
500 Allows access to the higher set-up levels:
SERV: service
vaBW:vaBW
551 Lock/unlock
Allows the locking of the panel controls and the inser-
tion of a protection code (consult the "Lock/unlock"
section).
552 Buzzer tone
Permits adjustment of the buzzer tone.
Minimum Off, Maximum 10, Default 5
751 Current reading
Allow the real value of the welding current to be dis-
played.
752 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
List of set up parameters (TIG)
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.
2 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 0.0sec., Maximum 99.9sec., Default 0.1sec.
3 Initial current
Allows regulation of the weld starting current.
Allows a hotter or cooler welding pool to be obtained
immediately after the arc striking.
Parameter setting: Amperes (A) - Percentage (%).
Minimum 5A-1%, Maximum Imax-500%, Default 50%
5 Initial current time
Allows setting of the time for which the initial current is
maintained.
Parameter setting: seconds (s).
Minimum off, Maximum 99.9s, Default off
6 Slope-up
Allows you to set a gradual passage between the initial
current and the welding current. Parameter set in sec-
onds (s).
Minimum off, Maximum 99.9s, Default off
7 Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 5A, Maximum Imax, Default 100A
8 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.
