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.

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.
