The serviceability of a product or structure utilizing the LF-72 wire feeder is and must be the sole responsibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in using the LF-72 wire feeder. These variables include, but are not limited to, welding procedure, plate chemistry and tempera- ture, weldment design, fabrication methods and ser- vice 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 responsi- ble for welding settings.
