FIGURA A.12 – CONEXIÓN DE NA-3 A R3S-400, 600, O 800 CON COMPENSADOR DE LA
N.D.
N.A.
THE ABOVE DIAGRAM SHOWS THE ELECTRODE CONNECTED POSITIVE. 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 CONTROL CABLE GROUND LEAD TO THE FRAME TERMINAL MARKED
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 AWG 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.
N.D. UPPER TERMINAL STRIP DOES NOT APPEAR ON OLDER R3S MACHINES. LEADS A, B, AND C SHOULD THEN BE TAPED UP. THERE WILL
BE NO ADJUSTMENT OF VOLTAGE BY THE AUTOMATIC CONTROL BOX VOLTAGE CONTROLS.
N.E. IF A VARIABLE VOLTAGE (V.V.) BOARD IS PRESENT IN THE AUTOMATIC CONTROLS, THE JUMPER LEAD ON THE V.V. BOARD MUST BE
CONNECTED TO PIN "L."
N.F. IF USING AN OLDER CONTROL CABLE, CONNECT LEADS #75, #76, AND #77 TO LEADS #75, #76, AND #77 OF THE TERMINAL STRIP,
RESPECTIVELY.
