LF-74 Wire Feeder, Bench Model, Heavy Duty
4-Roll Heavy Duty Industrial Feeder

Product Number:  K2426-5

Designed for MIG and cored wire welding in job shop and manufacturing environments, the rugged LF-72 and LF-74 wire feeders are built to deliver reliable performance day after day. The heart of these feeders is the highly engineered 2-roll or 4-roll MAXTRAC™ drive system, delivering strong and consistent feeding force for tough applications.

Select the 2-roll LF-72 for most .035-.045 wire applications. Select the 4-roll LF-74 for large diameter wires, longer gun cables or long boom conduit or hard automation applications.
