NEGATIVE
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 POSITION THE SWITCH ON THE POWER SOURCE (IF EQUIPPED) TO
PROPER POLARITY. REVERSE THE LEADS ON THE BACK OF THE AMMETER AND VOLTMETER IN THE AUTOMATIC CONTROL BOX. ALSO
REFER TO NOTE N.F.
N.A. WELDING CABLES MUST BE OF PROPER CAPACITY FOR THE CURRENT AND DUTY CYCLE OF IMMEDIATE AND FUTURE APPLICATIONS.
N.B. 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. IF THE LENGTH OF THE WORK LEAD CIRCUIT IS SHORT, AND CONNECTIONS CAN BE
EXPECTED TO BE RELIABLE, THEN CONTROL CABLE LEAD #21 DOES NOT NEED TO BE EXTENDED AND CAN BE DIRECTLY CONNECTED
TO TERMINAL #21 ON THE TERMINAL STRIP. NOTE THAT THIS IS NOT THE PREFERRED CONNECTION BECAUSE IT ADDS ERRORS TO THE
WIRE FEEDER VOLTMETER READING.
N.C. TAPE UP BOLTED CONNECTION.
N.D. CONNECT THE CONTROL CABLE GROUND LEAD TO THE FRAME TERMINAL MARKED
THE POWER SOURCE GROUNDING TERMINAL STIP (MARKED
MUST BE PROPERLY CONNECTED TO ELECTRICAL GROUND PER THE POWER SOURCE OPERATING MANUAL.
N.E. IF A VARIABLE VOLTAGE BOARD IS PRESENT IN THE AUTOMATIC CONTROLS AND THE DC-400 DIODE KIT OR CV-400 OR CVI-500 DIODE
OPTION IS NOT USED, THE JUMPER LEAD ON THE V.V. BOARD MUST BE CONNECTED TO PIN "L" TO PERMIT THE INCH DOWN BUTTON
TO OPERATE. THIS JUMPER, HOWEVER, WILL DISABLE THE COLD START/AUTOSTOP FEATURE OF THE AUTOMATIC CONTROLS, PERMITTING
ONLY HOT STARTING TECHNIQUES TO BE USED.
N.F. IF LEAD #21 IS TO BE CONNECTED TO THE TERMINAL STRIP, CONNECT TO TERMINAL #21 THAT MATCHES WORK POLARITY. THIS
CONNECTION MUST BE CHANGED WHENEVER THE ELECTRODE POLARITY IS CHANGED. THIS DOES NOT APPLY TO DC-400S BELOW CODE
9200 WITH POLARITY SWITCH.
