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 the

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 9001:2000 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
