Welding Cables Connections - Lincoln Electric IDEALARC CV 420 Bedienungsanleitung

1. Power Switch ON/OFF (O/I): It controls the
machine power input. Be sure the power source is
connected to the mains supply before turning power
on ("I").
2. Power Indicator Light: It indicates that the power is
on.
3. Thermal Indicator Light: It indicates that the
machine is overloaded or that the cooling is not
sufficient.
4. Low Inductance Negative Output Socket: The low
inductance connection is typically used for short arc
welding of mild steel, particularly on thin materials or
when using CO shielding gas.
2
5. High Inductance Negative Output Socket: The high
inductance connection is more suitable for short arc
welding in heavier work or when using 75% Argon /
25% CO shielding gas. The connection produces a
2
softer arc and a flatter bead with more wash-in than
the low inductance connection. Spray type transfer
is possible with either connection.
6. Wire Feeder Receptacle: 14-pins receptacle for
wire feeder. Provides connections for auxiliary
power of wire feeder.
7. Wire Feeder Voltmeter Switch: This switch selects
the polarity of the wire feeder voltmeter, if so
equipped. When the welding torch is positive (MIG,
Outershield and some Innershield processes), set
the switch to "+". When the welding torch is
negative (most Innershield applications), set the
switch to "-".
8. Positive Output Socket: Allows the connection, with
the power cable, to the wire feeder.
9. Covered Hole: For CO
accessories, K14009-1 CO
10. Fuse: This fuse protects the wire feeder supply
circuit (see Spare Parts).
11. Power Input Cable: Connect the proper plug to the
input cable then into the rated output according to
appropriate rules. Only qualified personnel shall
connect this plug.
12. Cooler Power Supply Socket (For water cooled
model only): For supplying the cooler unit. The
socket has an output of 230V, 2.5A and is protected
by the circuit breaker [13].
13. Circuit Breaker (For water cooled model only):
Protects the Cooler Power Supply socket [12]. It
shuts off the power supply when the current
exceeds 2.5A. Press it to restore the power supply.
14. Cooler (For water cooled model only): It refrigerates
the water cooled welding torch. The cooler works
continuously.
Read and understand the cooler manual before
connecting it to the machine.

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 LINC FEED 33 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,
cable K10347-PG-xM or K10347-PGW-xM)
Use the shortest possible cable lengths.
Machine and Circuit Protection
The CV420 / CV505 is protected against overheating,
overload and accidental short-circuits.
