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 engine 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
electrode holder to the negative (–) port, and
the ground clamp to the positive (+) port.
2. Select the appropriate electrode for the
material and process being performed. See
Table 5B
for selecting an electrode.
3. Place the ground clamp on the work piece
and insert the appropriate welding rod into
the electrode clamp.
4. Start the engine (
See Section 5.2, Engine
Start-up and Shutdown Procedure
).
