Insert the plug of input supply cable into the main
socket.
•
Switch ON the machine with the "Power Switch".
•
Insert the electrode wire into the torch.
•
According to selected welding mode and material
thickness set proper welding voltage and wire
feeding speed. The chart below can be useful for
welding setting selection:
•
Obeying the appropriate rules, you can begin to
weld.
Changing Polarity
1.
For Positive Polarity (DC +):
•
connect Welding Torch Cable to the Positive
(+) output terminal.
•
connect Return Welding Cable to the Negative
(-) output terminal.
This is the typical configuration for the Metal Inert
Gas (MIG).
2.
For Negative Polarity (DC -):
•
connect Welding Torch Cable to the Negative
(-) output terminal.
•
connect Return Welding Cable to the Positive
(+) output terminal.
This is the typical configuration for most of the
Innershield wires (Flux Cored Arc Welding Self-
Shielded / FCAW-S).
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.
WARNING
Maintenance or repairs
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.
