To choose the welding start mode, 2T, 4T or 3L, select
the corresponding symbol.
Mode 2T.
The machine begins welding when the torch trigger is
pressed, and stops when released. With mode 2T , you
can also choose the parameter HSA (Automatic Hot Start)
and the parameter CRA (Final Crater filler).
The 2 parameters HSA and CRA can be enabled at the
same time, or individually.
Once the parameter HSA has been enabled, the opera-
tor can adjust the Start current from 10 to 200% of the
welding current.
The Current time can also be adjusted from 0.1 to 10
seconds. The Connection time between the Start cur-
rent and the welding current can also be adjusted from 0.1
to 10 seconds. To adjust Start current values, Current
time and Connection time, enter Main Menu by select-
ing the key F MENU and using the key PARAMETERS enter
the process parameters menu. Turn knob 2 to select
the parameter, press it to enter the regulation screen and
turn it to adjust the value.
and the crater filling current (Crater Current) from 0.1 to
10 seconds. The operator can also adjust the crater filling
current from 10 to 200% of the welding current.
The duration of this current can also be adjusted from 0.1 to
10 seconds of the Crater filling time.

Mode 4T.
To begin welding press and release the torch trigger; to
stop welding press and release it again. Together with
mode 4T you may also select function HSA (automatic
hot start) and function CRA (final crater filling). (See 2T
Mode).
Mode 3L.
Specially well suited to weld aluminium. The HSA and
CRA functions are inhibited when mode 3L is activated.
3 currents are available that can be used in welding by
means of the welding torch start key.
The current and the connection time values are set as
follows:
Start Current. Start current, adjustable from 10 to 200%
of set welding current.
Connection Time. Possibility of adjusting from 0.1 to
10 seconds. Defines the connection time between Start
Current and welding current and between welding
current and crater filling current (crater filling at the
welding end)
Crater current may be adjusted from 10 to 200% of set
welding current.
Welding starts at the welding torch key pressure.
The recalled current will be the Start current.
This current is kept as long as the welding torch trigger
is held down; when the welding torch trigger is released
this current connects to the welding current, which is
