Input Fuse and Supply Wire Considerations
Refer to Page A-1 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
is
currents.
