 Limited Warranty shall not apply to:

1.

Consumable components; such as contact tips,

fail due to normal wear. (Exception: brushes and
relays are covered on all engine-driven products.)

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

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.
