Improve productivity with the NA-3S, NA-4, or NA-5 automatic wire feeders. These systems have been specially designed to deposit more weld metal at faster travel speeds which eliminates bottlenecks and cuts costs.



• Solid-state controls allow precise control of welding procedures, striking characteristics, as well as bead size and shape.

• Easily adjusted for a wide range of processes, feed speeds and wire sizes.

• Compact units with excellent flexibility to fit into simple fixtures or the most complex automated production lines.

• Rugged construction minimizes downtime and maintenance costs.



• Submerged arc Recommended
