The Spreadarc™is designed to oscillate an automatic
welding head for continuous welding at high duty cycles.
The Spreadarc™is compatible with the NA-3, NA-4, NA-5
and Power Feed™10A Lincoln®automatic welding heads
and ideal for hardfacing applications.
The operator can set the oscillation travel speeds
and dwell times at either end of the stroke to provide
smoother bead edges through a digital control panel
on the front of the machine. Additionally, the jog mode
allows the operator to position the welding nozzle in
the correct starting location for a particular weld seam.
