INPUT CONNECTION
Only a qualified electrician should connect
the input leads to the POWER WAVE
®
S350.
Connections should be made in accor-
dance with all local and national electrical
codes and the connection diagrams.
Failure to do so may result in bodily injury or death.
--------------------------------------------------------------------
A 15 ft. (4.6m) power cord may be provided and wired into the
machine
*
.
For Single Phase Input
Connect green lead to ground per National Electrical Code.
Connect black and white leads to power.
Wrap red lead with tape to provide 600V insulation.
For Three Phase Input

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 circuit 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
®
S350 automatically adjusts to work with dif-
ferent input voltages. No reconnect switches settings are
required.
