Lincoln Electric SVM194-A A2.3, Engine, When starting and stopping welding or using auxil

These units are also capable of providing 3 KVA of 115/230 volts of 60 cycle AC auxiliary power.

The Classic® 300D Perkins uses the Perkins 404C-22 industrial water-cooled diesel engine.

DESIGN FEATURES Control Panel

Both the engine and the welder controls are located on one recessed panel at the exciter end of the machine. The welder controls consist of a five step “Current Range Selector” switch and a “Fine Current Adjustment” rheostat. The welder is equipped with a “Start” button, an “Ignition” switch, an “Idler” control switch, and a “Glow Plug” button for easier cold weath- er starting.

The control panel also contains an engine temperature gauge, a battery charging ammeter, an oil pressure gauge, for auxiliary power one three prong grounding type receptacles, one GFCI receptacle and circuit breakers for protection.

RATED OUTPUT

250A @ 30V

300A @ 32V

The Classic® 300D Perkins has an Electronic Engine Protection System. In the event of sudden low oil pres- sure or high coolant temperature, the engine immedi- ately shuts down. The Classic® 300D Perkins has a current range of 40-350 DC amps with output ratings as follows:

The Classic® 300D Perkins is a heavy duty, engine dri- ven, DC arc welding power source, capable of provid- ing 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® 300D Perkins will provide constant voltage output for running the LN-7,LN-23P, or LN-25 wire feeders. (The Wire Feed Module is factory installed on the K1643-4). The optional K924-5 Remote Control Kit, provides a remote control rheostat for remote fine current and open circuit voltage adjustment.

INSTALLATION				A2.3
	All Copper Windings - For long life and dependable
	operation.		Idler - The Classic®	300D Perkins is
	Engine
	equipped with an electronic automatic engine idler. It
	automatically increases and decreases engine speed
	when starting and stopping welding or using auxil-
	iary power. A built-in time delay permits changing
	electrodes before the engine slows to its low idle
	speed. The “Idler” control switch on the panel locks the
	idler in high idle position when desired.
	Auxiliary Power - 3.0 KVA of nominal 115/230V, 60Hz,
	AC. Output voltage is maintained within ± 10% at all
	loads up to rated capacity. (See			Optional Features
	Section C for Power Plug Kit.)
	GFCI Receptacle - One UL approved 115V ground
	fault circuit interrupter duplex type receptacle is stan-
	dard. See the MAINTENANCE section for detailed
	information on testing and resetting the GFCI recepta-
	cle.
	Welder Enclosure - The complete welder is rubber
	mounted on a rugged steel “C” channel base.
	The output terminals are placed at the side of the
	machines so that they are protected by the door. The
DUTY CYCLE	output terminals are labeled (+) and (-).
	Cranking System - A 12 volt electric starter is stan-
100%	dard.
60%	Air Cleaner - Heavy duty two stage dry type.
	Muffler	- A muffler and stainless steel exhaust outlet
	elbow are standard.

Engine Hour Meter - A meter to record hours of oper- ation.

Engine Protection - The system shuts the engine down in the event of sudden low oil pressure or high coolant temperature. A warning light on the control panel will indicate such a fault. To reset the engine for restarting, turn the ignition switch off then on.

Oil Drain Valve - A ball valve, hose and clamp are standard.

Remote Control - The Remote / Local Switch and Receptacle are standard.
