5.4.1 WELDER OPERATING PROCEDURE
5.4.1.1 CC (CONSTANT CURRENT) MODE
CC (Constant Current) Mode is commonly referred to as -
Stick Welding, Arc Welding, or Shielded Metal Arc
Welding (SMAW)
1. With the motor shut off, insert the twist lock
connections of the ground clamp and the
electrode holder cables into the welder
connection ports on the control panel. For
Direct Current Electrode Positive (DCEP)
connect the electrode holder to the positive
(+) port, and the ground clamp to the
negative (–) port. For Direct Current
Electrode Negative (DCEN) connect the

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.
