Lincoln Electric IM982 RED-D-ARC DX500e (CE) - Manual (Page 19)

A-8 INSTALLATION
DX500e (CE) (RED-D-ARC)
A-8
Connection of the LN-25 to the DX500e (CE). Shut
off welder before making any electrical connec-
tions.
------------------------------------------------------------------------
The LN-25 with or without an internal contactor may
be used with the DX500e (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 DX500e (CE).
1. Shut the welder off.
2. For electrode Positive, connect the electrode
cable to the "+" terminal of the welder and work
cable to the "-" terminal of the welder. For elec-
trode Negative, connect the electrode cable 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 DX500e (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 sens-
ing circuit will cause the DX500e (CE) engine to
go to the high idle speed, the wire will begin to
feed and the welding process started. When weld-
ing 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
DX500e (CE) is started.
