1. POWER SWITCH
- Place the lever in the “ON”
position to energize the machine. When the power is on
the output will be energized in STICK (SMAW) mode and
TIG (GTAW) if the remote is set to local control. At
power up the thermal Light and Fan will turn on for
approximately 3 seconds.
2. OUTPUT CONTROL
- This controls the output
current. Control is provided over the entire output range
of the power source with (1) turn of the control knob. This
control may be adjusted while under load to change
power source output. When using remote control this
function becomes the limit setting.
3. LOCAL/REMOTE SWITCH
- Place in the
“LOCAL” position to allow output adjustment at the
machine. Place in the “REMOTE” position to allow output
adjustment at remote pot or amptrol. In Remote, the
machine output control pot is the limit setting for remote
control.
4. MODE SWITCH
CC -Stick (SMAW) Use this mode for all stick welding.
Output energized when machine is on.
TIG (GTAW) Optimized for touch start use. Short circuit
current is limited to approximately 20 amps to aid in touch
starting.
In TIG (GTAW) mode, the Local/Remote switch also con-
trols if the output is energized.

gy in CC Stick (SMAW). The Hot Start can be either
turned on or off. When on, it provides a striking current at
160% of the set current or 275A whichever is larger then
quickly reverts to the set current in 0.4 second.
