Thank you and congratulations on choosing Miller. Now
you can get the job done and get it done right. We know
you don’t have time to do it any other way.

That’s why when Niels Miller first started building arc
welders in 1929, he made sure his products offered
long-lasting value and superior quality. Like you, his
customers couldn’t afford anything less. Miller products
had to be more than the best they could be. They had to
be the best you could buy.

Today, the people that build and sell Miller products continue the
tradition. They’re just as committed to providing equipment and service
that meets the high standards of quality and value established in 1929.

This Owner’s Manual is designed to help you get the most out of your
Miller products. Please take time to read the Safety precautions. They will
help you protect yourself against potential hazards on the worksite. We’ve

made installation and operation quick and easy.
With Miller you can count on years of reliable
service with proper maintenance. And if for
some reason the unit needs repair, there’s a
Troubleshooting section that will help you
figure out what the problem is. The parts list
will then help you to decide which exact part
you may need to fix the problem. Warranty and
service information for your particular model
are also provided.

Miller is the first welding
equipment manufacturer in
the U.S.A. to be registered to
the ISO 9001 Quality System
Standard.

Working as hard as you do
– every power source from
Miller is backed by the most
hassle-free warranty in the
business.

From Miller to You

Miller offers a Technical
Manual which provides
more detailed service and
parts information for your
unit. To obtain a Technical
Manual, contact your local
distributor. Your distributor
can also supply you with
Welding Process Manuals
such as SMAW, GTAW,
GMAW, and GMAW-P.
