Lincoln Electric IM981 RED-D-ARC DX300e (CE) - Manual (Page 17)

A-6 INSTALLATION
DX300e (CE) (RED-D-ARC)
A-6
Connection of the LN-25 to the DX300e (CE).
Shut off welder before making any electrical con-
nections.
------------------------------------------------------------------------
The LN-25 with or without an internal contactor may
be used with the DX300e (CE). See the appropriate
connection diagram in Section F.
NOTE: The LN-25 (K431) Remote Control Module
and (K432) Remote Cable are not recommended for
use with the DX300e (CE).
1. Shut the welder off.
2. For electrode Positive, connect the electrode
cable from the LN-25 to the "+" terminal of the
welder and work cable to the "-" terminal of the
welder. For electrode Negative, connect the elec-
trode cable from the LN-25 to the "-" terminal of
the welder and work cable to the "+" terminal of
the welder.
3. Attach the single lead from the front of the LN-25
to work using the spring clip at the end of the lead.
This is a control lead to supply current to the wire
feeder motor; it does not carry welding current.
4. Set the MODE switch to the "CV-WIRE " position.
5. Set the "WELD TERMINALS" switch to "WELD
TERMINALS ON".
6. Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
7. Set the "IDLE" switch to the "AUTO" position.
When not welding, the DX300e (CE) engine will
be at the low idle speed. If you are using an LN-25
with an internal contactor, the electrode is not
energized until the gun trigger is closed.
8. When the gun trigger is closed, the current sensing
circuit will cause the DX300e (CE) engine to go to
the high idle speed, the wire will begin to feed and
the welding process started. When welding is
stopped, the engine will revert to low idle speed
after approximately 12 seconds unless welding is
resumed.
If you are using an LN-25 without an internal con-
tactor, the electrode will be energized when the
DX300e (CE) is started.
------------------------------------------------------------------------
WARNING
CAUTION
• The installation complies with the National
Electrical Code and all other applicable electri-
cal codes.
• The premises is isolated and no feedback into
the utility system can occur. Certain laws require
the premises to be isolated before the generator
is linked to the premises. Check your local
requirements.

CONNECTION OF LINCOLN ELECTRIC
WIRE FEEDERS
Connection of LN-15 to the DX300e (CE)
These connections instructions apply to both the LN-
15 Across The-Arc and Control Cable models. The
LN-15 has an internal contactor and the electrode is
not energized until the gun trigger is closed. When the
gun trigger is closed the wire will begin to feed and the
welding process is started.
• Shut the welder off.
• For electrode Positive, connect the electrode cable
to the "+" terminal of the welder and work cable to
the "-" terminal of the welder. For electrode
Negative, connect the electrode cable "-" terminal
of the welder and work cable to the "+" terminal of
the welder.
• Across The-Arc Model:
Attach the single lead from the front of the LN-15 to
work using the spring clip at the end of the lead. This
is a control lead to supply current to the wire feeder
motor; it does not carry welding current.
Set the "WELD TERMINALS" switch to "WELD TER-
MINALS ON".
• Control Cable Model:
Connect Control Cable between Engine Welder and
Feeder.
Set the MODE switch to the "CV-WIRE " position.
Set the "WELD TERMINALS" switch to "REMOTELY
CONTROLLED".
Set the "WIRE FEEDER VOLTMETER" switch to
either "+" or "-" as required by the electrode polarity
being used.
Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
Set the "IDLE" switch to the "AUTO" position.
