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.
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.
4.
To handle this machine, lift from below by means of a suitable
nylon belt.
2.4
SELECTING A LOCATION
SPECIAL INSTALLATION MAY BE REQUIRED WHERE GAS-
OLINE OR VOLATILE LIQUIDS ARE PRESENT. WHEN LO-
CATING EQUIPMENT, ENSURE THAT THE FOLLOWING
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 from the rear panel of the welder to the
pressure 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.

START-UP
1.
Switch on the machine (Ref. 3 - Picture 1 Page 3.)
2.
Set the power switch (Ref. 4 - Picture 1 Page 3.) to an inter-
mediate position.
3.
Remove the nozzle and wire guide tube from the torch, press
the torch button 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 exerts on the feed roller; the setting must en-
sure that the welding 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.
WELDING WIRE CAN CAUSE INJURY.
Never point the torch towards the body or towards
other metals when unwinding welding wire.
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.
