INSTALLATION

IMPORTANT: BEFORE CONNECTING, PREPARING OR US-
ING EQUIPMENT, READ SAFETY PRECAUTIONS.
2.1

MACHINE ACCESSORIES

1. Unpack the equipment and components to complete the ma-
chine assembly.
2. Leave the machine on the wood pallet (if used) or lift it after
fitting the special eye-bolts. With a 13 hex wrench to remove
the eight screws (four on the left and four on the right) under
the front panel; fit the two castor wheels and refit the screws.
3. Remove the two screws securing the machine to the pallet,
located on the cylinder support.
4. Raise the rear section of the machine slightly to rotate the
pallet and thus release the rear section.
5. Remove the screws from the axle and proceed with assem-
bly of the fixed wheels.
6. Fit the handles.
7. Assemble the pulling set stand using the four screws provid-
ed on the top centre of the generator cover.
8. Remove the pulling set packaging and position it on the stand
as soon as it is assembled. Make sure that the two stands are
coupled.
9. Connect the multi polar plug and the umbilical cord power
plug to the appropriate generator sockets.
2.2 CONNECTING THE POWER SOURCE TO THE MAINS
ELECTRICITY SUPPLY.
SERIOUS DAMAGE TO THE EQUIPMENT MAY RESULT IF
THE POWER SOURCE IS SWITCHED OFF DURING WELDING
OPERATIONS.
1. Ensure that the power supply socket is equipped with the
fuse specified in the table.
2. Before inserting the power plug, to avoid damage to the gen-
erator, check that the mains voltage corresponds to the re-
quired power supply.
3. 3-phase welders are factory-set to be powered at 400 V.
4. If voltage needs to be modified, open the machine and
change the connection as specified.

2.3 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.
For models 250A, 300A and 350A
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.
For models 450A
To lift these machines use the special eye-bolts provided.

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.
