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, and our extensive service
network is there to help fix the problem.
Warranty and maintenance 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
