WARNING

HAVE QUALIFIED PERSONNEL DO THE INSTAL- LATION WORK. TURN THE ENGINE OFF BEFORE WORKING INSIDE THE MACHINE. IN SOME CASES IT MAY BE NECESSARY TO REMOVE SAFETY GUARDS TO PERFORM REQUIRED INSTALLATION. REMOVE GUARDS ONLY WHEN NECESSARY AND REPLACE THEM WHEN THE INSTALLATION REQUIRING THEIR REMOVAL IS COMPLETE. ALWAYS USE THE GREATEST CARE WHEN WORKING NEAR MOVING PARTS.

LN-15, LN-22, LN-25 Connection — Instructions cov- ered under “Operation”.

LN-7 Connection — An LN-7 can be connected to SA- 250, SAE-300, SAE-350, SAE-400 and SAE-400 WELD’N AIR engine welders that have AC auxiliary power by using a K240 Contactor Kit. Connect the con- tactor kit to the engine welder and LN-7 per S17525 or S15416 connection diagram that is sent with the K240 Contactor Kit. The engine welder 115 volt receptacle will supply the AC power that is needed. Place the welder idler control in the high position before welding. When the LN-7 is connected to an SA-250 or SAE-350, it will not run at low idle when the idle control is in the automatic position. The plug connecting the K240 Contactor Kit to the SA-250 or SAE-350 auxiliary power receptacle must be disconnected to allow the engine to run at low idle.

CAUTION

ANY SPEED UP OF THE ENGINE RPM BY CHANGING THE GOVERNOR SETTING OR OVER- RIDING THE THROTTLE LINKAGE WILL CAUSE AN INCREASE IN THE AC AUXILIARY VOLTAGE. IF THIS VOLTAGE GOES ABOVE 140 VOLTS, THE LN-7 CONTROL CIRCUIT AND/OR THE CV ADAPTER CIRCUIT WILL BE DAMAGED! THE ENGINE GOVERNOR SETTING IS PRESET AT THE FACTORY — DO NOT ADJUST ABOVE RPM SPECIFICATIONS LISTED IN ENGINE WELDER OPERATING MANUAL.

The following tools and materials are recommended for attaching the CV Adapter to an engine welder:

1.Measuring tape, hammer, center punch and electric drill with 13/32" drill bit. This is only needed for SA- 250 engine welders that do not have mounting holes in fuel tank rail.

2.Set of socket wrenches.

3.11/32" wrench and 3/8" nut driver or pliers.

4.1/2" open end wrench and 9/16" wrench.

5.Screwdriver.

6.Electrical insulating tape.

K384 CV ADAPTER TO SA-200 ENGINE WELDER

NOTE: BEFORE INSTALLING CV ADAPTER, START ENGINE WELDER AND USE A DC VOLTMETER TO CHECK THE POLARITY OF THE RED AND BLACK LEADS CONNECTED TO THE AUXILIARY POWER RECEPTACLE. THE RED LEAD SHOULD BE NEGA- TIVE AND THE BLACK LEAD SHOULD BE POSI- TIVE. IF THE POLARITY IS NOT CORRECT, REFER TO ENGINE WELDER OPERATING MANUAL FOR INSTRUCTIONS TO FLASH THE EXCITER TO OBTAIN THE CORRECT POLARITY.

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 roof assembly and bracket cover (cover on top and at rear of generator). (See Figure 2.) Also, remove the two gas tank support mounting bolts on the side opposite the output studs.

2.Mount CV Adapter (nameplate should have an “SA” above the code number) to the gas tank sup- port holes. Use one 3/8" bolt with hardware removed in Step 1 and one stud on Adapter. One 3/8" bolt will not be used as a 3/8" stud from the Adapter case replaces it. In mounting the unit, be sure the fuel line and choke cable are not pinched. (See Figure 1.)

NOTE: FOR STEPS 3 THROUGH 10, REFER TO S17514 OR S17515 CONNECTION DIAGRAMS FOR THE APPROPRIATE WELDER CODE NUMBER. CV ADAPTER CONTROL LEADS ARE NOT COLOR CODED ON ALL UNITS.
