MIG Welding
Power Source
Issued January 2005 • Index No. DC/20
Fan-On-Demand
™
cooling system
operates only when needed,
reducing noise, energy use and the
amount of contaminants pulled
through machine.
Primary voltage display saves time
and assures operator that power
source is correctly set for available
input voltage without having to
remove side panels.
85% power efficiency means unit
costs less to operate.
The Power of Blue
®
.
115 VAC auxiliary power provides 10 A of circuit-
breaker-protected power for water circulators, etc.
600 A maximum output (450 A at 100% duty cycle)
meets the high output needs of demanding applications.
Optional remote on/off provides
ability to turn the power source on
and off when power source is
located away from your work.
Wind Tunnel Technology
™
protects
electrical components and PC
boards from contamination.
Variable, electronic inductance
control
helps to minimize spatter and
optimize weld-bead wetting action.

Power source is warranted for 3 years, parts and labor.
Original main power rectified parts are warranted for 5 years.
Quick
Specs
Line voltage compensation keeps
power constant even if power input
varies by ±10%. Ensures consistent
weld performance.
Pulsed MIG capabilities with
optional Optima control reduces
spatter and distortion, allows better
out-of-position puddle control, and
provides potential reduction of fume
particle emission.
Lightweight, aerospace-grade
aluminum case offers protection
with the benefit of reduced weight.
Unique case design protects internal
components from dirt and dust. To
connect power cord and/or set unit
up for correct input power, remove
the easy-to-handle panel (1/3 case).
The remaining two-thirds of the case
never needs to be removed!.
Auto Remote Sense enables unit to
automatically use remote control if
connected to remote control receptacle.
Remote control circuit protection
prevents damage from high frequency
and shorted control cables.
Large, dual digital meters
display both volts and amps for
quick and easy viewing by an
operator. Voltmeter is presettable
for ease of setting weld output.
A hold function lets the operators
view actual welding output when
the arc is broken.
