K385-1 Cv Adapter To Sae-300, Sae-400 Or Sae-400 Weld'n Air Engine Welders - Lincoln Electric CV ADAPTER IM309-D Operator's Manual

B-13
K385-1 CV ADAPTER TO SAE-300, SAE-400 OR
SAE-400 WELD'N AIR ENGINE WELDER
NOTE: BEFORE INSTALLING CV ADAPTER ON ENGINE
WELDERS WITH DC AUXILIARY POWER, START ENGINE
WELDER AND USE A DC VOLTMETER TO CHECK THE POLAR-
ITY OF THE RED AND BLACK LEADS CONNECTED TO THE
AUXILIARY POWER RECEPTACLE. THE RED LEAD SHOULD
BE NEGATIVE AND THE BLACK LEAD SHOULD BE POSITIVE.
IF THE POLARITY IS NOT CORRECT, REFER TO ENGINE
WELDER OPERATING MANUAL FOR INSTRUCTIONS TO
FLASH THE EXCITER TO OBTAIN THE CORRECT POLARITY.
Only use K385-1 CV Adapter that has a code number
above 8785 on SAE-300, SAE-400 and SAE-400
WELD'N AIR engine welders with AC auxiliary power
and Code Number above 8812.
WARNING
• TURN THE ENGINE OFF WHILE INSTALLING
THIS ACCESSORY.
• KEEP HANDS, HAIR, CLOTHING AND TOOLS
AWAY FROM MOVING PARTS WHEN STARTING
OR OPERATING ENGINE.
-----------------------------------------------------------------------
1. Remove the upper bracket cover or the wrap-
around bracket cover on older welders with AC
auxiliary power. Also, remove the two fuel tank
support mounting bolts on the side opposite the
output terminals. See Figure 12. On the SAE-400
(with codes 10601, 10856 and 10884) and all
WELD'N AIR, remove the guards mounted on the
inside of the front control panel.
2. Mount the K385-1 loosely in position as shown in
Figure B and Figure 13 for SAE-400 (Codes 9783
and above) or loosely in position as shown in
Figure A and Figure 13 for SAE-400 WELD'N AIR.
It is important that the CV Adapter be positioned
flush against the fuel tank rail. Take care not to
pinch any leads or lines.

NOTE: FOR STEPS 3 THROUGH 13, REFER TO THE
PROPER CONNECTION DIAGRAM IN THIS MANU-
AL FOR THE WELDER WITH THE APPROPRIATE
TYPE OF AUXILIARY POWER AND CODE NUMBER.
CV ADAPTER CONTROL LEADS ARE NOT COLOR
CODED ON ALL UNITS.

point and connect it to CV Adapter lead 503 using
#10 x 1/4 screw and nut provided. Insulate con-
nection with tape.
• (For codes 8812 through 10400, 10549 and 10664,
10665) Disconnect existing brown field lead (that
runs from the generator field) from the center ter-
minal of the Job Selector rheostat, and connect it
to the CV Adapter lead 509 using #10x1/4 screw
and nut provided. Insulate the connection with tape
(requires 115V insulation). On SAE-400 WELD'N
AIR models a second brown lead exists on the Job
Selector rheostat center terminal. This lead runs to
the remote control switch and is to be left in place.
• (For SAE 400 and WELD N' AIR with codes
10601, 10602, 10856, 10884 and 10885) Remove
the existing brown field lead from the 500Ω resister
and connect it to the CV Adapter lead 509 using the
#10-1/4 screw and nut that is provided. Insulate the
connection with tape.
