If voltage needs to be modified, open the machine and
change the connection as specified.

HANDLING AND TRANSPORTING THE POWER
SOURCE
OPERATOR SAFETY: WELDER’S HELMET - GLOWES -
SHOES WITH HIGH INSTEPS.
The machine is easy to lift, transport and handle, though the fol-
lowing procedures must always be observed:
1.
Do not lift by means of the handle
2.
Always disconnect the power source and accessories from
main supply before lifting or handling operations.
3.
Do not drag, pull or lift equipment by the cables.
To lift these machines take them from the bottom with a suitable
nylon strap, pay attention to the pulling set. If necessary discon-
nect it and carry it in two lifts.
2.4
SELECTING A LOCATION
Special installation may be required where gasoline or volatile liq-
uids are present. When locating equipment, ensure that the fol-
lowing guidelines are followed:
1.
The operator must have unobstructed access to controls and
equipment connections.
2.
Use rating plate to determine input power needs.
3.
Do not position equipment in confined, closed places. Venti-
lation of the power source is extremely important. Avoid
dusty or dirty locations, where dust or other objects could be
aspirated by the system.
4.
Equipment (Including connecting leads) must not obstruct
corridors or work activities of other personnel.
5.
Position the power source securely to avoid falling or over-
turning. Bear in mind the risk of falling of equipment situated
in overhead positions.
2.5
SAFETY GAS CYLINDER INSTALLATION
1.
Place the cylinder on the rear section of the welder and se-
cure by means of the relative chain.
2.
Bolt the pressure reducer to the cylinder.
3.
Connect the tube coming out from the umbilical cord to the
reducer.
4.
Set the pressure reducer outlet to minimum.
5.
Open the cylinder valve slowly.
2.6
WIRE REEL INSTALLATION
1.
Put the wire reel in the relative spool so that the two rotate to-
gether.
2.
Adjust the spool brake by means of the central nut on the lat-
ter, so that the reel rotates easily (on some spools the adjust-
ment nut is not visible, but is accessible after withdrawing the
retainer tab).
3.
Open the upper bridge of the wire feed unit
4.
Check that the rollers are suited to the diameter of the wire to
be used; otherwise change.
5.
Straighten an end section of the wire and cut it.
6.
Pass the wire over the two lower rollers and insert in the torch
connector tube until it protrudes from the latter by approx. 10
cm.
7.
Close the upper bridge of the wire feed unit and check that
the wire is positioned in the relative groove.
8.
Connect the torch and insert the protruding wire section into
the sleeve, taking care that the control pins are fitted correctly
in the seats and the connector nut is tightened fully down.
2.7
START-UP
1.
Switch on the machine
2.
Set the power switch (Ref. 10 - Picture 1 Page 4., Ref. 16 -
Picture 2 Page 5.) to an intermediate position.
3.
Remove the nozzle and wire guide tube from the torch, press
the button (Ref. 8 - Picture 3 Page 5., Ref. 12 - Picture 1 Page
4.) and feed the wire until it protrudes from the front section
of the torch. While feeding wire through the torch, use the
handwheel to adjust the force that the wire pressure roller ex-
erts on the feed roller; the setting must ensure that the weld-
ing wire moves regularly without slipping on the rollers and
without deforming. Fit the torch with a suitable wire guide
tube according to the type of wire used.
4.
Secure the wire guide tube, and ensure that the diameter cor-
responds to the wire used.
5.
Refit the gas nozzle.
6.
Open the gas cylinder valve.
7.
Connect the ground clamp to the workpiece on a section free
of rust, paint, grease or plastic.
