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.

3. Remove existing yellow lead from the outside ter- minal of the reversing switch and connect it to the same terminal on the reversing switch that is con- nected to the red lead (a green lead may also be on this terminal).

4. Remove existing blue resistor lead from reversing switch and connect both ends of this blue lead to the same resistor terminal to store lead.

5. Remove existing blue field lead from its connection point and connect it to CV Adapter lead 503 using #10 x 1/4 screw and nut provided. Insulate con- nection with tape.

6.

•(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.
