SAFETY PRECAUTIONS
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
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 Pipeliner 200G is a heavy duty engine driven DC
arc welding power source capable of providing DC
constant current output for stick welding and DC TIG
welding. With the addition of the optional K623-1 Wire
Feed Module the Pipeliner 200G will provide constant
voltage output for running the LN-25 wire feeder.
The Pipeliner 200G 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 GM 3.0L 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, a battery charging ammeter, an oil pres-
sure gauge and engine coolant temperature gauge.
The control panel also contains a three prong ground-
ing type receptacle for auxiliary power.
Welding Generator
The Pipeliner 200G uses the old style, round, all cop-
per FJW Generator frame which provides the cus-
tomer with the original “Classic” pipe welding arc.
Engine Idler
The Pipeliner 200G is equipped with an electronic
automatic engine idler. It automatically increases and
decreases engine speed when starting and stopping
welding or using auxiliary 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 the 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 High Energy Distributor Type electronic ignition is
standard.
