GENERAL DESCRIPTION

The Classic® 300 D 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 300 D 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 K1643-2). The optional K924-4 or K924-5 Remote Control Kit (Both field installed) See Section C for description.

The Classic 300 D has Diesel Engine Protection. In the event of sudden low oil pressure or high coolant temperature, the engine immediately shuts down. The Classic 300 D has a current range of 40-350 DC amps with output ratings as follows:

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

The Classic 300 D uses the Perkins 104-22 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 weather starting.

The control panel also contains an engine tempera- ture gauge, a battery charging ammeter, an oil pres- sure gauge, two three prong grounding type recepta- cles and four circuit breakers for auxiliary power.

All Copper Windings - For long life and dependable operation.

Engine Idler - The Classic 300 D is equipped with an electronic automatic engine idler. It automatically increases and decreases engine speed when start- ing and stopping welding or using auxiliary power. A built-in time delay permits changing elec- trodes 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 for Power Plug Kit.)

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 output terminals are labeled (+) and (-).

Cranking System - A 12 volt electric starter is stan- dard.

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.
