Welding Cables Connections
Insert the plug of the work cable into the socket [4] or [5].
The other end of this cable connects to the work piece
with the work clamp.
Connect the wire feeder to the power source:

insert the positive welding cable into the output
socket [8].

insert the wire feeder control cable into the socket [6]
(see "Accessories" section, Source/wire feeder cable
K10347-PG-xM or K10347-PGW-xM).
Use the shortest possible cable lengths
Machine and Circuit Protection
The CV425 / CV510 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 thermal
protection circuit will turn on the output current again,
when the machine is cooled.
The CV425 / CV510 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.
Transport
Figure 4.
To ensure safety transport it is to:

Lift only power source without gas cylinder , cooler
and wire feeder,

Screw down an eye bolt and apply load axially in 45
degree angle in accordance to the drawing.

Ensure equal length of lifting lines.

Maintenance
For any repair
maintenances, it is recommended to contact the nearest
Technical Service Center or Lincoln Electric. Repairs
and modifications performed by unauthorized service or
personnel will cause, that the manufacturer's warranty
will become null and void.
Any noticeable damage should be reported immediately
and repaired.
Routine maintenance (everyday)

Check condition of insulation and connections of the
work leads and insulation of power lead. If any
insulation damage
immediately.

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
at list once every year)
Perform the routine maintenance and, in addition:

Keep the machine clean. Using a dry (and low
pressure) airflow, remove the dust from the external
case and from the cabinet inside.

If it is required, clean and tighten all weld terminals.
The frequency of the maintenance operations may vary
in accordance with the working environment where the
machine is placed.
Do not touch electrically live parts.
Before the case of welding machine will be removed, the
welding machine had to be turned off and the power lead
had to be disconnected from mains socket.
Mains supply network must be disconnected from the
machine before each maintenance and service. After
each repair, perform proper tests to ensure safety.
