CLASSIC I
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
1.75 kw 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.
