Remove the gas nozzle and unscrew the current nozzle
of the torch. Press the torch button until the wire comes
out. BE CAREFUL to keep your face away from the end
lance while the wire is coming out, screw up the current
nozzle and fit the gas nozzle.
Open the canister adapter and adjust the gas flow to 8 –
10 l/min.
During welding, the display screen 1 displays the actual
work current and voltage. The displayed values may
be slightly different to those set. This can depend on
numerous different factors - type of torch, thickness
different to nominal thickness, distance between current
nozzle and the material being welded, and the welding
speed.
The current and voltage values, at the end of the welding
operation remain stored on the display 1 where the word
"HOLD is displayed. To display the set values, the handle
2 will have to be moved slightly, while, by pushing the
torch button without welding, the display screen 1 shows
the empty voltage value and a current value of 0.
If, while welding the maximum current and voltage values
are exceeded, said values are not stored on the display
and the written "HOLD" is not displayed.
• In order to mount the cooling unit Art.1681 (optional)
remove the closing panel (see drawing) and follow the
instructions located inside the relevant compartment.
NOTE If 0.6mm diameter wires are used the welding torch
sheath should be replaced with one of suitable internal
diameter. If the internal diameter of the sheath is too big it
does not guarantee smooth wire feeding.
Sloping planes.
Since this welding machine is equipped with wheels with-
out brake, do not position it on sloping planes, to prevent
machine tilting or uncontrolled movement.

The screen displays the welding current in Amperes,
la welding voltage in Volts, the suggested thickness
in mm and the welding wire speed in m/min. During weld-
ing the display shows the current and voltage values in a
continuous manner and, once welding is completed, the
last value in Amperes and Volts is displayed along with
the HOLD word.
When the display is in HOLD, BLUE color appears. If If
we press on the center of the display opens a screen that
displays the main parameters of the last welding: the arc
time in seconds switched on, the main current time in
seconds, the average current in amperes, the average
voltage Volt and the total energy in Kj.
Ampere and volt parameters are synergically adjusted by
means of knob 2.
