Miller Electric DU-OP User manual

Quick

Specs

Weld meters — digital ammeter

and presettable voltmeter allow

monitoring of welding output for

each welder.

Multi-arc welding is here! One

dependable engine and two high-

performance arcs allow operators

to work independent of each other.

It’s a one-of-a-kind, go-anywhere

engine drive.

Miller Du-Op®Engine-Driven

Welder/Generator

Issued May 2008 • Index No. ED/10.9

Thermal overload protection

prevents machine damage if the

duty cycle is exceeded or airflow

is blocked.

Two 14-pin remote controls can

be used for precise adjustment

of amperage or voltage along

with contactor.

Increase profits with this multi-arc

machine by completing even your

most demanding jobs in half the

time compared to conventional

engine-driven welders. With two

arcs in one engine drive, fewer

machines are required for a job.

Double the amperage output

with a switch that parallels both

outputs to a single side. This

provides a safe and easy way to

run large electrodes, stud weld,

or carbon-arc gouge.

5,500 watts of AC generator

power independent of welding

output. Two 120 V, 20 A GFCI

duplex receptacles. Two 230 V,

20 A duplex receptacles.

Hot Start™provides positive stick

electrode starts to make it easy

to start all types of electrodes.

The Power of Blue®

Welder/generator is warranted by Miller for 3 years, parts and labor.

Engine is warranted by Deutz for 2 years.
