ENGLISH
1) Hold down the gas PURGE button (ref.12 page 9) for a few seconds to purge the
gas.
2) Press the INCH button (ref.13 page 9) for manual advance of the wire, so as to
make the wire run through the torch until it is just protruding from the nozzle.
3) Set the welding parameters.
4) Perform welding: press and hold down the torch button (the green Led (ref.2 page
9) lights up); for a short time (0.5 seconds) the gas will come out (pre-gas), then the
wire will start to come out and the arc will be lit; the arc will remain lit as long as the
button is held down.
5) It is possible to vary the characteristic of the arc using the ARC TRIM function. It
is recommended to start welding with the value set at 0. If any splashes occur during
welding, increase the ARC TRIM value; instead, if the wire tends to stick and burns
with difficulty, decrease the ARC TRIM value.
6) During welding the left-hand display (ref.5 page 9) shows the value of the set wire
speed (expressed in m/min) or of the real current (expressed in Ampere), depending
on whether the reading of the current with the button A (ref.25 page 9) is enabled;
on the right-hand display (ref.7 page 9) you can see the real voltage value
(expressed in Volt).
End of welding:
7) When the button is released the arc goes out; gas will then start to come out for
the time set with the post-gas function.
8) At the end of welding, both displays will keep for a few seconds the real current
and voltage values obtained during welding.
MIG 4 TIME WELDING
Preparing the machine
Proceed as described for MIG 2 TIME welding.
Regulating the MIG 4T welding parameters: manual regulation
1) Press the SELECT MODE button (ref.29 page 9) until the MIG 4T mode led
(ref.31 page 9) lights up.
2) The letters MIG 4t will appear on the displays (ref.5-7 page 9) for 2 seconds.
3) Regulating the wire speed – proceed as described for MIG 2 TIME welding
