BLW-400SSW — LOAD APPLICATION
Single Phase Load
Always be sure to check the nameplate on the welder/AC
generator and equipment to insure the wattage, amperage
and frequency requirements are satisfactorily supplied by
the welder/AC generator for operating the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require 130—
150% more wattage than the rating on the nameplate, as
the wattage is influenced by the efficiency, power factor
and starting system of the equipment.
The power factor of this welder/AC generator is 1.0. See
Table 11 below when connecting loads.
!
When connecting a resistance load such as an
incandescent lamp or electric heater, a capacity of up
to the generating set’s rated output (kW) can be used.
!
When connecting a fluorescent or mercury lamp, a
capacity of up to the generating set’s rated output (kW)
multiplied by 0.6 can be used.
!
When connecting an electric drill or other power tools,
pay close attention to the required starting current
capacity.
CAUTION:
Motors and motor-driven equipment draw
much greater current for starting than
during operation.
An inadequate size connecting cable which cannot carry
the required load can cause a voltage drop which can burn
out the appliance or tool and overheat the cable.
The idle control is operated at minimum load capacity of
100W. If the load capacity is less than 100W, change the
idle control switch to the "OFF" position.
CAUTION:
Before connecting this welder/AC
generator to any building’s electrical
system, a licensed electrician must install
an isolation (transfer) switch. Serious
injury or death may result without this
transfer switch.
When connecting ordinary power tools, a capacity of up to
the generating set’s rated output (kW) multiplied by 0.8 can
be used. Use Table 12 below for proper welding electrode
size for power capacity.
With AC loads of more than 150W (such as lighting
equipment, motor-powered tools, submersible water pumps,
etc.), the engine runs at high speed. When a no load condition
is produced, the engine automatically slows down.
Turn the idle control switch to the “ON” (up) position when
AC loads of more than 150W are connected. Turn the idle
control switch to the “OFF” (down) position when AC loads
of less than 100W or when a magnetic switch is used.

NOTE
If wattage is not given on the
equipment's name plate, approximate
wattage may be determined by
multiplying nameplate voltage by the
nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
