How to Set the Controls
Assume you want a normal soft arc and about 135
amps, using a 5/32" (4.0 mm) electrode:
1. Set the "Job Selector" at the center of the black
range.
2. Set the "Current Control" to read 135 amps on the
black dial.
3. Start to weld.
4. If you want a little more current, turn the "Job
Selector" up (counterclockwise) to increase cur-
rent. If you want a little less current, turn the "Job
Selector" down (clockwise) to decrease current.
5. If dialing the desired current with the "Job
Selector" moves the setting outside the black
range causing undesirable arc characteristics, turn
the "Job Selector" back to the center of the black
range. Then turn the "Current Control" up or down
a little as needed. Readjust the "Job Selector" for
the exact characteristics and current desired.
REMOTE CONTROL
A receptacle and "Local/Remote" control switch on the
lower front control panel and a remote control box with
100 ft. (30.5 m) of cord for adjusting the OCV at the
welding site are standard. Putting the switch in the
"REMOTE" position allows fine current control at the
remote control box while placing the switch in the
"LOCAL" position allows fine current control at the "Job
Selector" on the machine. When using the optional
field installed CV adapter (K385-[ ]) the "Local/Remote"
switch is only active in the "VV" mode.
AUXILIARY POWER CONTROLS
NOTE: GFCI receptacles our an option and if installed,
see the MAINTENANCE section for detailed informa-
tion on testing and resetting the GFCI receptacle.
115 VAC Receptacle
One 20 amp, 115 VAC duplex receptacle provides 115
VAC for auxiliary power. A total of 26 amps can be
drawn from this receptacle.
OPERATION
230 VAC Receptacle
One 15 amp, 230 VAC duplex receptacle provides 230
VAC for auxiliary power. A total of 13 amps can be
drawn from this receptacle.
Circuit Breakers
The circuit breakers provide separate overload current
protection for each half of the 115 V duplex receptacle.
The circuit breakers provide overload current protec-
tion in both current carrying wires of the 230 V duplex
receptacle.
Ground Stud
Provides a connection point for connecting the
machine to earth ground. For the safest grounding pro-
cedure refer to "Machine Grounding" in the INSTALLA-
TION section of this manual.
