K345-10 - Lincoln Magnum 350 Innershield Gun, 10ft, .068-5/64 Wire

Lincoln Electric Magnum 350A FCAW-SS Welding Gun (K345-10)

The Lincoln Electric Magnum 350A FCAW-SS Welding Gun (K345-10) represents over four decades of engineering excellence in the field of semiautomatic flux-cored, self-shielded (FCAW-S) welding. Designed to meet the rigorous demands of heavy industrial environments, this gun combines a high amperage rating with a durable, user-friendly design. It is specifically rated for 350 amps at a 60% duty cycle, making it a robust choice for continuous welding operations where reliability is paramount. The gun is engineered to handle wire diameters ranging from .068 to 5/64 inches (1.7-2.0 mm), catering to a specific range of structural and fabrication applications.

Construction quality is a hallmark of the Magnum Classic series. The K345-10 features a reinforced rubber jacket that encases the cable, adding significant strength and resistance to cuts, abrasion, and heat—common hazards on active job sites. Despite its rugged build, the gun remains lightweight and flexible, ensuring that operators can maneuver the tool with ease during long shifts. The 10-foot (3-meter) cable length provides a practical balance between reach and wire feedability, suitable for standard bench work or localized structural repairs.

Operational efficiency is enhanced by the inclusion of a heavy-duty gun trigger switch, designed for positive electrical contact and long service life, reducing the frequency of maintenance or replacement. Additionally, the gun features a reduced wire feed speed thumb switch, placing critical control directly at the operator's fingertips. The 90-degree gun tube angle is standard on this model, offering optimal ergonomics for vertical and overhead positions or when accessing tight corners. Meeting NEMA specification EW3, the Lincoln Magnum 350 provides professional welders with a dependable tool for high-quality Innershield welding.
