CONNECTION OF THE LN-25 TO THE
RANGER 300 D AND DLX "ACROSS
THE ARC" USING THE K444-1 REMOTE
CONTROL (SEE FIGURE C.2.)
1. Shut the welder off.
2. Connect the electrode cable from the LN-25 to the
ELECTRODE terminal of the welder. Connect the
work cable to the WORK terminal of the welder.
NOTE: Welding cable must be sized for current and
duty cycle of application.
NOTE: Figure C.2 shows the electrode connected for
negative polarity. Use the Polarity switch on the
Ranger 300 to select the desired electrode polarity.
Change the LN-25 polarity switch.
3. Attach the single lead from the LN-25 to the work
using the spring clip on the end of the lead. This is
only a sense lead - it carries no welding current.
4. Place the IDLER switch in the "AUTO" or "HIGH"
position as desired.
