POWER SOURCES (SUPPLIED BY USER) FOR THE N6000 SYSTEM
WARNING
Direct current/electrode positive (reverse polarity) is required for the N6000
System. Use direct current/electrode negative (straight polarity) for special
applications. Do not use alternating current with the system.
CAUTION
Power sources must be rated for 100% duty cycle at the amperage required
for the size (diameter) electrode used. Contact the manufacturer of the power
source for paralleling procedures or with questions concerning amperage ratings
and duty cycles.
NOTE
Recommendations are based on a 4-volt DC drop per 100 Ft. Length given is
one-half the sum of lengths of electrode and ground leads. Inadequate grounding
may cause cable overheating. There should be at least 1 square inch of contact
per 1000 amps.
DC welding power sources with a minimum O.C.V. of 60 volts and 45 volts at rated load supply
the DC current for the N6000 system. Use single power sources rated at 1,000 or 1,500 amperes
to get enough amperage for larger diameter electrodes. Power sources may be paralleled in
combinations of two or more similar units. Anytime power sources are paralleled Use N6000
Torches with either rectifier or motor-generator power sources.
