The Lincoln Electric LN-25 wire feeder is recommend-
ed for wire feed welding with the Classic I.
CONNECTION OF THE LN-25 TO THE
CLASSIC I “ACROSS THE ARC” WITH
WIRE FEED MODULE (SEE FIGURE C.1.)
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.1 shows the electrode connect-
ed for positive polarity. To change polari-
ty, shut the welder off and reverse the
electrode and work cables at the Classic I
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.
