Lincoln Electric IM514-A manual General Description, Design Summary

A-2 INSTALLATION A-2

GENERAL DESCRIPTION

The Classic I is a heavy duty engine driven DC arc welding power source capable of providing DC con- stant current output for stick welding and DC TIG welding. With the addition of the optional K384 CV Adapter for K6090 thru -4 or the K623-1 Wire Feed Module for K6090-5, -6, the Classic I will provide con- stant voltage output for running the LN-25 wire feeder.

The Classic I has a current range of 40-300 DC amps with output ratings as follows:

RATED	OUTPUT	DUTY CYCLE
200A	@ 28V	60%
200A	@ 40V	60%

The units are also capable of providing 1.75 kw of 115V DC auxiliary power.

This unit uses the Continental TM27 industrial water- cooled gasoline engine.

DESIGN SUMMARY

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, “Ignition” switch, “Idler” control switch, hour meter, choke cable, a battery charging ammeter, and an oil pressure light.

The control panel also contains a three prong ground- ing type receptacle for auxiliary power.

Welding Generator

The Classic I uses the old style, round, all copper FJW Generator frame which provides the customer with the original “Classic” pipe welding arc.

Engine Idler

The Classic I is equipped with an electronic automatic engine idler. It automatically increases and decreases engine speed when using starting and stopping weld- ing or using auxiliary power. A built-in time delay per- mits changing electrodes before the engine slows to its low idle speed. The “Idler” control switch on the panel locks the idler in full speed position when desired.

Auxiliary Power

1.75kw of nominal 120V DC. Output voltage is main- tained within ± 10% at all loads up to rated capacity. (See Optional Features for power plug kits).

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 machine so that they are protected by the door. The output terminals are labeled (+) and (-).

Ignition System

A Distributor Type electronic ignition is standard.

Cranking System

A 12V electric starter is standard.

Air Cleaner

Heavy duty two-stage dry type

Exhaust

A muffler and rain cap are standard.

Engine Hour Meter

A meter to record the hours of operation.

Carburetor Deicing Kit

Prevents carburetor icing when outside temperature is 60°F/15.5°C or lower.
