4-5. Voltage Sensing Lead And Work Cable Connections For Multiple Welding Arcs A. Bad Setup 804 460-A 1 Welding Power Source 2 Electrode Cable 3 Feeder Cable 4 Work Cable 5 Voltage Sensing Lead 6 Wire Feeder 7 Workpiece This arrangement is a bad setup due to sensing leads being directly in the current flow path of the welding arc. Interaction between welding circuits will affect voltage drop in the workpiece. The voltage drop across the workpiece will not be measured correctly for the voltage feedback signal. Voltage feedback to the welding power sources will not be correct ...

MOVING PARTS can cause injury.  Keep away from moving parts such as fans.  Keep away from pinch points such as drive rolls.  Have only qualified persons remove doors, panels, covers, or guards for maintenance as necessary.  Keep hands, hair, loose clothing, and tools away from moving parts.  Reinstall doors, panels, covers, or guards when maintenance is finished and before re- connecting input power. MAGNETIC FIELDS can affect pacemakers.  Pacemaker wearers keep away from servicing areas until consulting your doctor. OVERUSE can cause OVERHEATING.  Allow cooling perio ...

3-11. Electrical Service Guide  CAUTION: INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of 50/60 Hz (10%) power at 10% of rated input voltage. Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a generator with automatic idle device (that idles engine when no load is sensed) to supply input power to this welding power source. Actual input voltage should not exceed ± 10% of indicated required input voltage. If actual input voltage is outside of this range, output may not be a ...

3-8. Connecting To Weld Terminals Tools Needed: 803 410-B / 803 778-A 1 2 3/4 in (19mm) 6 4 5 Do not place anything between 3 weld cable terminal and copper bar.  Turn off power before connecting to weld output terminals.  Failure to properly connect weld cables may cause excessive heat and start a fire, or damage your machine. Determine total cable length in weld circuit (both positive and negative cables combined) and maximum welding amperes. See Section 4-1 to select proper cable size. 1 Positive (+) Weld Output Terminal 2 Negative (−) Weld Output Terminal Connect p ...
