For Negative polarity, connect the electrode cable to the “-” stud. These connections should be checked periodically and tightened if necessary. When welding at a considerable distance from the welder, be sure you use ample size welding cables. RECOMMENDED COPPER CABLE SIZES Amps Duty Cycle Cables Sizes for Combined Length of Electrode Plus Work Cable Up to 200 ft. 60.96 m 200 to 250 ft. 200 to76.2 m 250 100% 1 1/0 300 60% 1/0 2/0 PRE-OPERATION SERVICE CAUTION READ the engine operating and maintenance instructions supplied with this machine. WARNING • Stop engine while fueling. • Do not smoke when fueling. • Keep sparks and flame away from tank. • Do not leave unattended while fueling. • Wipe up spilled fuel and allow GASOLINE fumes to clear before starting can cause fire engine. or explosion. • Do not overfill tank, fuel expansion may cause overflow. GASOLINE FUEL ONLY OIL This unit is supplied from the factory with the engine crankcase filled with a high quality SAE 10W/30 oil. This oil should be acceptable for most typical ambient temperatures. Consult the engine operation manual for specific engine manufacturer’s recommendations. Upon receipt of the welder, check the engine dipstick to be sure the oil is at the “full” mark. DO NOT overfill. FUEL Fill the fuel tank with the grade of fuel recommended in the Engine Operator’s manual. Make sure the fuel valves on the sediment bowl and the water separator are in the open positions. COOLING SYSTEM The radiator has been filled at the factory with a 50-50 mixture of ethylene glycol antifreeze and water. Check the radiator level and add a 50-50 solution as needed (see engine manual or antifreeze container for alternate antifreeze recommendations) CLASSIC 300G A-4 A-4 INSTALLATION BATTERY CHARGING WARNING GASES FROM BATTERY can explode. • Keep sparks, flame and cigarettes away. BATTERY ACID can burn eyes and skin. • Wear gloves and eye protection and be careful when boosting, charging or working near battery. To prevent EXPLOSION when: • Installing a new battery - disconnect the negative cable from the old battery first and connect the negative cable to the new battery last. • Connecting a battery charger remove the battery from the welder by disconnecting the negative cable first, then the positive cable and battery clamp. When reinstalling, connect the negative cable last. • Using a booster - connect the positive lead to the battery first, then connect the negative lead to the ground lead on the base. To prevent ELECTRICAL DAMAGE when: • Installing a new battery. • Using a booster. Use correct polarity - Negative Ground. • To prevent BATTERY DISCHARGE, if you have an ignition switch, turn it off when engine is not running. • To prevent BATTERY BUCKLING, tighten nuts on battery clamp until snug. The Classic 300G is equipped with a wet charged battery. The charging current is automatically regulated when the battery is low (after starting the engine) to a trickle current when the battery is fully charged. When replacing, jumping or otherwise connecting the battery to the battery cables, the proper polarity must be observed. This system is NEGATIVE GROUND. CLASSIC 300G B-1 B-1 OPERATION SAFETY PRECAUTIONS WARNING Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions, and parts lists. ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing. • Insulate yourself from work and ground • Always wear dry insulating gloves. ENGINE EXHAUST can kill. • Use in open, well ventilated areas or vent exhaust outside. MOVING PARTS can injure. • Do not operate with doors open or guards off. • Stop engine before servicing. • Keep away from moving parts. See additional warning information at the front of this operator’s manual. Operate the welder with the doors closed. Leaving the doors open changes the designed air flow and can cause overheating. GENERAL DESCRIPTION The Classic® 300G is a heavy duty, engine driven, DC arc welding power source, capable of providing constant current output for stick welding or DC TIG welding. This welder is wound with all copper coils, rated at 300 amps/32 Volts, and provides other Classic features such as improved door latches and stainless hinges. With the addition of the optional K623-1 Wire Feed Module™ the Classic 300G will provide constant voltage output for running the LN-7, LN-23P, or LN-25 wire feeders. The optional K924-4 Remote Control Kit (field installed) provides a switch, or K924-5 Remote Control Kits provide a receptacle and a remote control rheostat for remote fine current and open circuit voltage adjustment. The Classic 300G has an electronic Engine Protection system. In the event of sudden low oil pressure or high coolant temperature, the engine immediately shuts down. The Classic 300G has a current range of ...
