Issued May 2007 • Index No. DC/19.2

14-pin receptacle provides quick,

direct connection to Miller 14-pin

wire feeders and accessories.

Internal digital voltage control

(DVC) enables operator to preset

weld voltage in the CV mode before

striking an arc.

Built-in arc control lets you get in

tight without sticking the electrode.

An electrode compensation circuit

ensures consistent arc control

performance regardless of the

electrode size.

DC multiprocess capability

provides versatility and outstanding

arc performance in CV (MIG) and

CC (Stick, TIG).

Power efficient for exceptional value

and return on your investment.

Fan-On-Demand

™

operates only

when needed reducing noise, power

consumption, and the amount of

airborne contaminants pulled

through the machine.

The Power of Blue

Power source is warranted for 3 years, parts and labor.

Original main power rectified parts are warranted for 5 years.

Input Power 3-Phase Power on all models

Rated Output 302: 300 A at 32 VDC, 100% Duty Cycle

452/562: 450 A at 38 VDC, 100% Duty Cycle

652/812: 650 A at 44 VDC, 100% Duty Cycle

Weight 302: 361 lb (164 kg)

452/562: 424 lb (192 kg)

652/812: 545 lb (247 kg)

115 V duplex receptacle provides

15 amps of auxiliary power.

Hot Start

™

makes it easier to start

difficult-to-start Stick electrodes

such as E-6010 and E-7018.

Simple control panel features single

range amperage/voltage adjustment.

Provides easy, efficient operation.

Digital voltmeter and ammeter are

easy to read, even at 30 ft (9.2 m).

Line voltage compensation ensures

consistent weld performance by

keeping output power constant even if

primary input power varies by ±10%.

Dimension 452/562

Power cord strain relief provided

for your convenience at installation.

Remote on/off capabilities allow

operator to turn power source

on/off from a distance.

Remote voltage control allows

operator to change voltage from

feeder.

Thermal overload protection light indicates

power shutdown. Helps prevent machine damage

if the duty cycle is exceeded or airflow is blocked.

PC board protection prevents the

wire feeder power or other stray

voltages (less than 115 VAC) from

harming the power source PC board.

Enclosed circuit boards provide

additional protection from

contaminants resulting in longer

service life.
