Input Connection
WARNING
ELECTRIC SHOCK can kill
Only a qualified electrician should connect the input
leads to the Power Wave. Connections should be made
in accordance with all local and national electrical codes
and the connection diagrams located on the inside of the
reconnect/input access door of the machine. Failure to
do so may result in bodily injury or death.
Use a three-phrase supply line. A 45mm diameter
access hole for the input supply is located on the case
back. Connect L1, L2, L3 and ground according to the
Input Supply Connection Diagram.
Input Fuse and Supply Wire
Considerations
Refer to Specifications page for recommended fuse and
wire sizes. 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 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
Welders are shipped connected for the highest input
voltage listed on the rating plate. To move this
connection to a different input voltage, see the diagram
located on the inside of the input access door, or the
Input Supply Connection Diagram below. If the Auxiliary
lead (indicated as ‘A’) is placed in the wrong position,
there are two possible results.
a) If the lead is placed in a position higher than the
applied line voltage, the welder may not come on at
all.
b) If the Auxiliary lead is placed in a position lower than
the applied line voltage, the welder will not come on,
and the two circuit breakers in the reconnect area
will open. If this occurs, turn off the input voltage,
properly connect the auxiliary lead, reset the
breakers, and try again.
