GENERAL DESCRIPTION
The BIG RED™ 600 is a diesel engine driven welder,
offering reliable DC arc welding performance, with
outstanding arc characteristics for all welding applica-
tions. The BIG RED™ 600 is both a rugged three
cylinder, diesel engine driven 600 amp DC arc welder
and 3.6 KW AC power generator. This powerful gen-
erator can be used to provide electricity for lights,
power tools, etc.
The BIG RED™ 600 delivers ideal DC arc characteris-
tic for each welding process. Stick electrode welding,
Scratch-Start TIG, or carbon arc gouging, to make the
BIG RED™ 600 the ideal all purpose engine driven
welder for on-site work.
The BIG RED™ 600 has “no PC Boards” and “no
electronics”.
The BIG RED™ 600 is service friendly with a minimal
number of major parts, simplifying in field servicing of
the BIG RED™ 600. The generator is a dual stator
and rotor design with two sealed bearings for mainte-
nance free service. The rotors are copper wound
design with two slip rings and brushes. The stators
are wound entirely with heavy gauge copper wire and
insulated with NEMA class F insulation material. The
stator is then impregnated with three layers of high
quality varnish. After the stator is assembled using tie
bars, the entire assembly Is covered with an environ-
mentally protective coating . These measures insure
trouble-free operation in the harshest environments.
RECOMMENDED APPLICATIONS
WELDER
The BIG RED™ 600 provides constant current DC
welding output for stick (SMAW) and TIG (GTAW)
welding (scratch start). In addition the Big Red can be
used for Arc Gouging with carbons up to 9.5 mm
(3/8”) diameter.
The BIG RED™ 600 is not recommended
for pipe
thawing.
GENERATOR
The BIG RED™ 600 provides smooth output for auxiliary
power and emergency standby power. The auxiliary power
is independent of the welding power and thus not effected
by the weld control settings. Full power is available provided
welding output is below 200 amps. Above 200 amps refer to
the Simultaneous Welding and Auxiliary Power chart in the
operation section of this manual.

SAFETY INSTRUCTIONS
Read and understand this entire section before
operating your BIG RED™ 600.
Do not attempt to use this equipment until you
have thoroughly read all operating and mainte-
nance manuals supplied with your machine. They
include important safety precautions, detailed
engine starting, operating and maintenance
instructions and parts lists.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
such as output terminals or internal
wiring.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside
• Do not stack anything near the engine.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts
------------------------------------------------------------------------
Only qualified personnel should operate this
equipment.

ADDITIONAL SAFETY PRECAUTIONS
Always operate the welder with the hinged door
closed and the side panels in place as these pro-
vide maximum protection from moving parts and
insure proper cooling air flow.
