Output Connections - Lincoln Electric POWER WAVE 345M C Bedienungsanleitung

G. Remote control receptacle.
H. Water connector (as standard on water cooled
models): For connecting water cooled torches.
I. Fast Mate adaptor (Female): For Ground cable.
NOTE: The rating plate is located on the rear panel of
the machine.
Water Cooler Connection and Supply
Socket Enabling
Connect the welding gun cooling unit to the auxiliary
socket placed on the PW345M C rear side; then press
the pusbutton near the socket for enabling the supply to
the cooler.
Be sure to disable the auxiliary socket if the cooler is
disconnected or not used.

Output Connections

Ground cable delivered with the machine has Twist-
Mate™ plugs for connection to the POWER WAVE 345M
C. Use the shortest possible cable lengths.
Changing Polarity
Connect the output lead of the Euroconnector to the
desired polarity and the ground lead to the other
terminal: the positive terminal marked (+) is the standard
configuration (see photo). This polarity is mainly used
on GMAW and FCAW-GS welding mode. The negative
terminal marked (-) is mainly used on FCAW-SS
(Innershield) welding mode.

Drive Rolls and Guide Tubes
Installation
•
Mount the wire spool on the output shaft so that, by
dragging the extremity of the wire, the spool turns
anticlockwise.
• The wire diameter must fit the diameter stenciled on
the visible side of drive rolls. If it is not the case,

unscrew the screws holding the rolls, turn them or
replace them with rolls that fit the wire diameter
used.
•
Every drive roll is provided with 2 grooves to allow
the feeding of wires with different diameters.
• Specific drive rolls are available for cored or
aluminium wires. It is also possible to configure the
wire feeder with 4 driven rolls (see "Accessories").
•
Lift the levers of ball bearings which press on drive
rolls.
•
Insert the wire inside the fitting inlet guide and let it
out from the torch adapter. Lower the levers
regulating the bearings. Use the adjustment nut to
modify the pressure of the bearings.
Idle Roll Pressure Setting
For small wire sizes and aluminum wires, the idle roll
pressure varies with type of wire, surface condition,
lubrication and hardness. An excessive pressure may
cause wire distortion. It may be jammed or break which
may cause an early wear and tear of the feeding motor.
Turn back the adjusting knob and repeat the operation.
A too low pressure may cause wire feeding irregularities.
Connecting the Welding Gun
• Position the gun connector located at the end of the
torch in front of the gun connector machine. Gently
push and screw the black locking nut.
•
Connect the gun to the gun adapter.
• Take off the gas guide from the gun extremity and
unscrew the contact tip. The wire must feed
regularly without any variation in wire feed speed. If
it is not the case, or if the wire slips, increase the
pressure setting using the with the adjustment nut
until the wire feed speed becomes regular.
•
Mount again the contact tip and the gas nozzle. Be
sure the that both the wire feed speed and the size
of contact tip are correct.
•
Connect the work clamp to the work piece or to the
welding table making sure that the clamp is
provided with a good quality contact (the surface of
work piece must be clean and must not show any
rust, paint or oily stains).
Internal switches (M)
