GENERAL DESCRIPTION

The BIG RED ® 600 is a diesel engine driven welder,
offering reliable DC arc welding performance, with out-
standing arc characteristics for all welding applications.
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 generator can
be used to provide electricity for lights, power tools,
etc.
The BIG RED ® 600 delivers ideal DC arc characteristic
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 elec-
®
tronics".
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 maintenance
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 var-
nish. After the stator is assembled using tie bars, the
entire assembly Is covered with an environmentally
protective coating . These measures insure trouble-
free operation in the harshest environments.

RECOMMENDED APPLICATIONS

WELDER
The BIG RED ® 600 provides constant current DC weld-
ing 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") diame-
ter.
The BIG RED ® 600 is not recommended for pipe
thawing.

GENERATOR

The BIG RED ® 600 provides smooth output for auxil-
iary power and emergency standby power. The auxil-
iary 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.
