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 Electric manufactures a full line of

welders and welding related equipment. For

information on other quality Miller products, contact your local Miller

distributor to receive the latest full line catalog or individual catalog sheets.

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

B. Information On Electromagnetic Fields (EMF)

!This equipment shall not be used by the general public as the EMF limits for the general public might be exceeded during welding.

This equipment is built in accordance with EN 60974−1 and is intended to be used only in an occupational environment (where the general public

access is prohibited or regulated in such a way as to be similar to occupational use) by an expert or an instructed person.

Wire feeders and ancillary equipment (such as torches, liquid cooling systems and arc striking and stabilizing devices) as part of the welding

circuit may not be a major contributor to the EMF. See the Owner’s Manuals for all components of the welding circuit for additional EMF exposure

information.

The EMF assessment on this equipment was conducted at 0.5 meter.

At a distance of 1 meter the EMF exposure values were less than 20% of the permissible values.
