CONNECTION OF THE LN-25 TO THE
CLASSIC III OR CLASSIC IIID (EQUIPPED
WITH K623-1 WIRE FEED MODULE)
“ACROSS THE ARC” (SEE FIGURE C.4.)
1. Shut the welder off.
2. Connect the electrode cable from the LN-25 to the
“+” terminal of the welder. Connect the work cable
to the “CV–” terminal of the welder.
NOTE: Welding cable must be sized for current and
duty cycle of application.
NOTE: Figure C.4 shows the electrode connected for
positive polarity. To change polarity, shut the welder
off and reverse the electrode and work cables at the
Classic III or Classic IIID
output terminals. Reverse the
LN-25 polarity switch.
3. Connect the K444-2 remote control cable to the 14
pin amphenol on the wire feed module.
4. Attach the single lead from the LN-25 control box
to the work using the spring clip on the end of the
lead. This is only a control lead — it carries no
welding current.
5. Place the IDLER switch in the “HIGH” position.
6. Adjust wire feed speed and voltage at the LN-25.
