DUTY CYCLE AND OVERHEATING

The duty cycle is the percentage of a 10 minute period for which
the welder can continue to weld without overheating. If the ma-
chine overheats, the welding current is shut off and the relative in-
dicator lamp illuminates. In this case, leave the machine to cool for
approx. 15 minutes and, before restarting, lower the welding cur-
rent value and relative voltage or reduce the work time.
Example: 250 A - 30% means working for 3 minutes at 250 A with
7 minutes rest time.

VOLT - AMPERE CURVES

Volt-ampere curves show the welder's maximum voltage and am-
perage output capabilities of the welding power source. Curves of
other settings fall under curves shown. See page XIII.

INSTALLATION

IMPORTANT: BEFORE CONNECTING, PREPARING OR USING
EQUIPMENT, READ SECTION 1.0 SAFETY PRECAUTIONS.
2.1

MACHINE ACCESSORIES

1. Unpack the equipment and components to complete the ma-
chine assembly.
2. Leave the machine on the wooden pallet, and use 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.
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.
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.
