clockwise increases the amperage or voltage, and
turning the power dial counterclockwise decreases the
amperage or voltage. The power dial may be adjusted
while welding.

Any combination of the 300 Power System output functions (compressor, generator, welder) used simultaneously at
capacity will have an adverse affect on engine running at full throttle.

Consult
Appendix A, Section A.3, Wattage Requirements for Common Receptacle Units
for a listing of wattage
requirements of various implements.
NOTE
The amps/volts display will read the set
value for five (5) seconds when the dial is
adjusted, and the actual output value five
(5) seconds after the dial has been
adjusted.
WARNING
Do not rely on the thermal overload
circuit breakers on the generator to
protect personnel, power tools, or the
generator. The thermal overload circuit
breakers on the generator require time to
overheat when the generator is operating
in an overload condition — they do not
provide instant protection against short
circuiting or overload conditions. Always
use GFCI protected extension cords and
power strips when using the generator.
