WARNING
Machine and Circuit Protection
Power Source is protected against overheating, overload
and accidental short-circuits.
If the machine is overheated, the thermal protection
circuit will decrease the output current to 0. The thermal
protection indicator [3] will turn on.
The Power Source is also electronically protected
against overload and accidental short-circuit. The
overload and short-circuit protection circuit automatically
reduces the output current to a safe value when it
detects an overload.
Maintenance
For any maintenance or repair operations it is
recommended to contact the nearest technical service
center or Lincoln Electric.
performed by unauthorized service centers or personnel
will null and void the manufacturers warranty.
The frequency of the maintenance operations may vary
in accordance with the working environment where the
machine is placed.
Any noticeable damage should be reported immediately.
Routine maintenance (everyday)

Check cables and connections integrity. Replace, if
necessary.

Remove the spatters from the welding gun nozzle.
Spatters could interfere with the shielding gas flow
to the arc.

Check the welding gun condition: replace it, if
necessary.

Check condition and operation of the cooling fan.
Keep clean its airflow slots.
Periodic maintenance (every 200 working hours but
not more rarely than once a year)
Perform the routine maintenance and, in addition:

Keep clean the machine. Using a dry ( and low
pressure) airflow, remove the dust from the external
case and from inside of the cabinet.

Check and tighten all screws.
Mains supply network must be disconnected from the
machine before each maintenance and service. After
each repair, perform proper tests to ensure safety.
