INPUT FUSE AND SUPPLY WIRE
CONSIDERATIONS
Refer to Specification Section for recommended fuse,
wire sizes and type of the copper wires. Fuse the
input circuit with the recommended super lag fuse or
delay type breakers (also called "inverse time" or
"thermal/magnetic" circuit breakers). Choose input
and grounding wire size according to local or national
electrical codes. Using input wire sizes, fuses or cir-
cuit breakers smaller than recommended may result in
"nuisance" shut-offs from welder inrush currents, even
if the machine is not being used at high currents.
INPUT VOLTAGE SELECTION
The POWER WAVE ® C300 automatically adjusts to
work with different input voltages. No reconnect
switches settings are required.
