NOTES

1. CONNECT PORTABLE FIELD CONTROL TO TERMINALS #75 AND #76.

2. WHEN NOT USING PORTABLE FIELD CONTROL, CONNECT A JUMPER ACROSS TERMINALS #75 AND *77.

4. FOR NORMAL VOLTAGE WELDING, CONNECT LEADS 7, 8 AND 9 TOGETHER AND INSULATE CONNECTION. INSULATE LEADS 10, 11 AND 12 SEPARATELY. FOR UNITS WITH LOW VOLTAGE OPTION SEE INSERT ABOVE. (THESE CONNECTIONS ARE MADE INTERNALLY ON LATEST MACHINES
