The serviceability of a product or structure utilizing
the LF-72 wire feeder is and must be the sole respon-
sibility of the builder/user. Many variables beyond
the control of The Lincoln Electric Company affect the

These variables include, but are not limited to, weld-
ing procedure, plate chemistry and temperature,
weldment design, fabrication methods and service
requirements. The available range of the LF-72 wire
feeder may not be suitable for all applications, and
the builder/user is and must be solely responsible for
welding settings.
