FIGURE A.3 – CONNECTION OF LN-8 TO AN IDEALARC R3S-400, 600 OR 800

N.A.

N.B.

THE ABOVE DIAGRAM SHOWS THE ELECTRODE CONNECTED FOR POSITIVE POLARITY. TO CHANGE POLARITY, TURN OFF THE POWER,

REVERSE THE ELECTRODE AND "TO WORK" LEADS AT THE POWER SOURCE, AND REVERSE THE "CONTROL SWITCH" AT THE POWER

SOURCE.

CONNECT THE LN-8 CONTROL CABLE GROUND LEAD TO THE FRAME TERMINAL MARKED

OR TO AN UNPAINTED FRAME SCREW. THE POWER SOURCE MUST BE PROPERLY GROUNDED.

N.A. ON EARLIER R3S-400, -600, AND -800 MACHINES, TERMINALS #67 AND #1 WERE ALSO ON THE TERMINAL STRIP.

N.B. WELDING CABLES MUST BE OF PROPER CAPACITY FOR THE CURRENT AND DUTY CYCLE OF IMMEDIATE AND FUTURE APPLICATIONS.

N.C. EXTEND LEAD #21 USING #14 OR LARGER INSULATED WIRE PHYSICALLY SUITABLE FOR THE INSTALLATION. AN S16586-[ ]

REMOTE VOLTAGE SENSING WORK LEAD IS AVAILABLE FOR THIS PURPOSE. CONNECT IT DIRECTLY TO THE WORK PIECE, KEEPING IT

ELECTRICALLY SEPARATE FROM THE WELDING WORK LEAD CIRCUIT AND CONNECTION. FOR CONVENIENCE, THIS EXTENDED LEAD

#21 SHOULD BE TAPED TO THE WELDING WORK LEAD. (THIS EXTENDED #21 LEAD CONNECTION REPLACES THE NEED TO EMPLOY THE

REMOTE WORK LEAD ACCESSORY ON LN-8 METER KITS WHICH HAVE A DIRECT WORK LEAD JACK).

N.D. IF USING AN OLDER LN-8 CONTROL CABLE (PRIOR TO USE OF A, B, AND C MARKING): CONNECT LEAD #75 TO #75 ON THE TERMINAL

STRIP, CONNECT LEAD #76 TO #76 ON THE TERMINAL STRIP, AND CONNECT LEAD #77 TO #77 ON THE TERMINAL STRIP.

N.E. UPPER TERMINAL STRIP (#75, #76 AND #77) MAY NOT APPEAR ON OLDER R3S MACHINES. LEADS A, B, AND C SHOULD BE TAPED UP.

THERE WILL BE NO ADJUSTMENT OF VOLTAGE BY THE LN-8 VOLTAGE CONTROL.
