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 80%
4 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%
40 Current reading
Allow the real value of the welding current to be dis-
played.
Allows the welding current display method to be set
(consult the "Interface personalisation" section).
41 Voltage reading
Allows the real value of the welding voltage to be dis-
played.
Allows the welding voltage display method to be set
(consult the "Interface personalisation" section).
44 Regulation step
Allows the regulation of a parameter with a step that
can be personalised by the operator.
Minimum 1, Maximum Imax, Default 1
45 CH1 External parameter
Allows the management of external parameter 1 (mini-
mum value, maximum value).
(Consult the "External controls management" section).
46 CH2 External parameter
Allows the management of external parameter 2 (mini-
mum value, maximum value).
(Consult the "External controls management" section).
47 Lock/unlock
Allows the locking of the panel controls and the inser-
tion of a protection code (consult the "Lock/unlock"
section).
48 Buzzer tone
Permits adjustment of the buzzer tone.
Minimum Off, Maximum 10, Default 5

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 3A-1%, Maximum Imax-500%, Default 50%
5 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
6 Welding current
Permits adjustment of the welding current.
Parameter set in Amps (A).
Minimum 3A, Maximum Imax, Default 100A
7 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 cur-
rent "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) - Percentage (%).
Minimum 3A-1%, Maximum Imax-500%, Default 50%
9 Basic current
Permits adjustment of the basic current in pulsed and
fast pulse modes.
Parameter set in Amps (A).
Minimum 3A-1%, Maximum Weld current-100%,
Default 50%
11 Pulsed frequency
Allows regulation of the pulse frequency.
Allows better results to be obtained in the welding of
thin materials and better aesthetic quality of the bead.
Parameter setting: Hertz (Hz) - KiloHertz (kHz).
Minimum 0.1Hz, Maximum 250Hz, Default 1.0Hz
12 Pulsed duty cycle
Allows regulation of the duty cycle in pulse welding.
Allows the peak current to be maintained for a shorter
or longer time.
Parameter setting: percentage (%).
Minimum 1%, Maximum 99%, Default 50%
13 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
14 Slope-down
Allows you to set a gradual passage between the weld-
ing current and the final current.
Parameter set in seconds (s).
Minimum off, Maximum 99.9s, Default off
