SAFETY PRECAUTIONS

DO NOT OPERATE SWITCHES ON CV ADAPTER
WHILE WELDING.

------------------------------------------------------------------------

VV OR CV WELDING

ANY LN-23P WIRE FEEDER OR CABLES
ATTACHED TO CV ADAPTER OUTPUT TERMINAL
AND STANDARD OUTPUT TERMINALS ARE
ALWAYS ENERGIZED WHEN ENGINE IS RUNNING
REGARDLESS OF MODE SWITCH POSITION.
STORE LN-23P GUN OR ELECTRODE HOLDER
SO THEY DO NOT CONTACT WORK WHEN NOT
WELDING.

------------------------------------------------------------------------

VV STICK WELDING

Place both mode switches on the CV Adapter to VV
Stick position. For units with remote control, place the
Remote Control Switch in the desired position.

NOTE: THE UPPER SWITCH MUST IN VV POSI-
TION BEFORE THE LOWER SWITCH CAN BE
PLACED IN VV POSITION. An interlocking handle
prevents operation of the switches in the wrong
sequence.

Connect the welding cables to the standard output ter-
minals of the engine welder and use the standard con-
trols to set the welding current. On the SAE-400, SAE-
500 and SAE-400 WELD’N AIR engine welders, the
polarity switch is disconnected so the standard “To
Work” terminal that has been relabeled “Positive” is
always positive, and the standard “Electrode” terminal
that has been relabeled “Negative” is always negative.

CV INNERSHIELD WELDING

Place both switches in CV Innershield position.

NOTE: THE LOWER SWITCH MUST BE IN THE
“CV” POSITION BEFORE THE UPPER SWITCH
CAN BE PLACED IN “CV” POSITION. An interlocking
handle prevents operation of the switches in the
wrong sequence. The “Job Selector” must be at
maximum.

For electrode negative Innershield welding, connect
the electrode lead of an LN-23P wire feeder to the
output terminal on the CV Adapter and connect the
work to the “To Work” standard SAE output terminal
that is relabeled “Positive”.

The standard SAE “Electrode” output terminal that is

relabeled “Negative” is not used for CV welding.

The output voltage is set in one of two ways. With the
CV Adapter Remote Control switch set in the “LOCAL”
position, the voltage is controlled with the control dial
on the CV Adapter. With the CV Adapter switch set in
“REMOTE” position, the voltage is controlled at the
LN-23P. Set the SAE “Current Control” to the 9
o’clock position for optimum welding characteristics
with innershield electrodes.
Changing the “Current Control” affects arc character-
istics.

For proper CV Adapter operation, the “Job Selector”
must be at maximum.
