CONNECTION OF THE LN-25 TO THE
CLASSIC II “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 connect-
ed for positive polarity. To change polari-
ty, shut the welder off and reverse the
electrode and work cables at the Classic II
output terminals. Reverse the LN-25
polarity switch.
3. 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.
4. Place the IDLER switch in the “HIGH” position.
5. Adjust wire feed speed and voltage at the LN-25.
