N.B. If LN-7 is equipped with a meter kit, extend LN-7 control cable

lead #21 from control cable with terminal strip connectors or from

14-pin receptacle using #14 AWG or larger insulated wire physically

suitable for the installation. An S16586-[LENGTH] remote

voltage sensing work lead may be ordered for this purpose.

Connect it directly to the work piece independent of the welding

Above diagram shows electrode connected positive. To change polarity,

turn power off, reverse the electrode and work leads at the power source and position the switch on wire feeder (if equipped )

to proper polarity. Also refer to note N.F.

For proper setting of switches on power source, see power source operating manual.
