Submerged Arc DC Wire Feeder
Improve productivity with the NA-3 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. Used for heavy duty fabrication and assembly line production, these units feature solid state controls for precise control of welding procedures – even to the most exacting requirements. Trust Lincoln automatic welding systems for troublefree operation!
ADVANTAGE
The LT-7 Tractor is a self-propelled mechanized wire feeder, designed for the submerged arc process with track system capabilities. It is self-guiding and easy to operate – only one operator is usually required. It is designed to be used with a variety of Lincoln DC constant voltage and constant current power sources. The rugged, lightweight unit permits quick movement to the next joint. Its compact size fits through small openings and confined spaces. Butt and fillet welds can be made on heavy plate or steel as light as 12 gauge (2.5mm). The LT-7 Tractor is ideal for the following applications: ship and barge building, storage tank erection, bridge deck installation, beam, girder or column fabrication, and long seams on heavy weldments.
► Solid state controls allow for precise control of welding
