4.1 MAINTENANCE OF THE WELDING INVERTER

In the case of maintenance inside the machine, make sure
that the switch (5) is in position "O" and
that the power cord is disconnected from the mains. It is
also necessary to periodically clean the
interior of the machine from the accumulated metal dust,
using compressed air.

4.2 PRECAUTIONS AFTER REPAIRS

After making repairs, take care to organize the wiring so
that there is secure insulation between the primary and
secondary sides of the machine. Do not allow the wires
to come into contact with moving parts or those that heat
up during operation. Reassemble all clamps as they were
on the original machine, to prevent a connection from
occurring between the primary and secondary circuits
should a wire accidentally break or be disconnected. Also
mount the screws with geared washers as on the
original machine.
