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