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.

S Use a towing vehicle prepared and capable of handling the

load.

S Be sure load is properly secured. Load includes welder/

generator, cables, tools, and approved accessories.

S Towing any trailer requires special awareness because of

the changed driving situation.

S When towing, it takes longer to start, stop, and pass − use

training and practice to avoid accidents.

S Turning and backing up present new problems − plan ah-

ead.

S Require each driver to be fully trained and experienced in

trailer towing before going out on the road.

S Holes are provided for mounting weld/power generator.

S Be sure trailer is fully prepared and connected to towing ve-

hicle.

S Observe maximum speed of 45 mph (72 kph) when towing.

S Do not modify or change the trailer in any way − changes

void the warranty. Read Owner’s Manual.

S Use only genuine factory parts as replacements.

S Adjust load on trailer so tongue weight is approximately 10%

of the gross trailer weight and center load side-to-side to re-

duce fishtailing.

S Tighten all parts, bolts, nuts, and mounting hardware.

OVERLOADING can cause serious injury or equipment

damage.

S Do not overload the trailer.

S The Gross Vehicle Weight Rating (GVWR) is the maximum total

trailer weight with the engine driven welding generator and all

equipment,

such as tools, cables, and shielding gas cylinder,

installed.

S The Gross Axle Weight Rating (GAWR) is the maximum

load-bearing capacity of the axle(s).

S Weigh trailer − adjust weight by removing accessory equipment if

necessary − call local authorities for nearest scale location.

S Use gross trailer weight to select a proper towing vehicle.

UNCONTROLLED TILTING OF TRAILER can result in personal

injury or equipment damage.

S Install generator according to Owner’s Manual with engine end

toward hitch end of trailer.

S Distribute weight so that trailer tongue weight is approximately

10% of the gross trailer weight.

INCORRECT TONGUE WEIGHT can cause fishtailing and loss

of control of towing vehicle resulting in serious injury and

equipment damage.

S Tongue weight is the amount of trailer weight that rests on the

towing vehicle hitch − that is, the downward pressure on the

coupler.

S Remove or adjust trailer load to get correct tongue weight.

S Do not let tongue weight exceed coupler and hitch rating.

S Use slower speeds when towing a trailer − never above 45 mph

(72 km/h) − to prevent fishtailing.

Miller’s True Blue® Limited Warranty shall not apply to:

1. Consumable components; such as contact tips,

cutting nozzles, contactors, brushes, relays, work

station table tops and welding curtains, or parts that

fail due to normal wear. (Exception: brushes and

relays are covered on all engine-driven products.)

2. Items furnished by Miller, but manufactured by others,

such as engines or trade accessories. These items are

covered by the manufacturer’s warranty, if any.

3. Equipment that has been modified by any party other than

Miller, or equipment that has been improperly installed,

improperly operated or misused based upon industry

standards, or equipment which has not had reasonable

and necessary maintenance, or equipment which has

been used for operation outside of the specifications for

the equipment.

4. Defects caused by accident, unauthorized repair, or

improper testing.

MILLER PRODUCTS ARE INTENDED FOR COMMERCIAL

AND INDUSTRIAL USERS TRAINED AND EXPERIENCED IN

THE USE AND MAINTENANCE OF WELDING EQUIPMENT.

The exclusive remedies for warranty claims are, at Miller’s

option, either: (1) repair; or (2) replacement; or, if approved in

writing by Miller, (3) the pre-approved cost of repair or

replacement at an authorized Miller service station; or (4)

payment of or credit for the purchase price (less reasonable

depreciation based upon use). Products may not be returned

without Miller’s written approval. Return shipment shall be at

customer’s risk and expense.

The above remedies are F.O.B. Appleton, WI, or Miller’s

authorized service facility. Transportation and freight are the

customer’s responsibility. TO THE EXTENT PERMITTED BY

LAW, THE REMEDIES HEREIN ARE THE SOLE AND

EXCLUSIVE REMEDIES REGARDLESS OF THE LEGAL

THEORY. IN NO EVENT SHALL MILLER BE LIABLE FOR

DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR

CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF

PROFIT) REGARDLESS OF THE LEGAL THEORY. ANY

WARRANTY NOT PROVIDED HEREIN AND ANY IMPLIED

WARRANTY, GUARANTY, OR REPRESENTATION,

INCLUDING ANY IMPLIED WARRANTY OF

MERCHANTABILITY OR FITNESS FOR PARTICULAR

PURPOSE, ARE EXCLUDED AND DISCLAIMED BY

MILLER.

Some US states do not allow limiting the duration of an implied

warranty or the exclusion of certain damages, so the above

limitations may not apply to you. This warranty provides

specific legal rights, and other rights may be available

depending on your state. In Canada, some provinces provide

additional warranties or remedies, and to the extent the law

prohibits their waiver, the limitations set out above may not

apply. This Limited Warranty provides specific legal rights, and

other rights may be available, but may vary by province.
