WITHOUT A MULTI-PROCESS SWITCH INSTALLED, DISCONNECT ALL ELECTRODE, WORK, AND CONTROL LEADS TO ANY WIRE FEEDERS. JUMPER 2 TO 4. OUTPUT TERMINALS WILL NOW BE ENERGIZED. PLACE MODE SWITCH IN VV FOR STICK AND CV (I) FOR AIR CARBON ARC. SEE OPERATING MANUAL FOR FURTHER INSTRUCTIONS.
N.C. CENTER TERMINAL OF FUSE HOLDER. N.D. WELDING CABLE MUST BE OF THE PROPER
CAPACITY FOR THE CURRENT AND DUTY CYCLE OF IMMEDIATE AND FUTURE APPLICATIONS. "POSITIVE". TO CHANGE THE POLARITY, TURN THE DC-600 OFF, AND REVERSE THE LEADS AT THE MULTI-PROCESS SWITCH. CONNECTION DIAGRAM, CONNECT ELECTRODE AND WORK LEADS TO THESE TERMINALS INSTEAD OF THE POWER SOURCE OUTPUT TERMINALS.
