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.

AUTOMATIC WIRE FEEDERS

• Arc length remains constant during oscillation to provide a more

uniform penetration.

• Dwell timers provide delay periods atthe end-points of the stroke for

smoother bead edges.

• The oscilation travel speed of the arc is uniform across the bead.

• Bright, digital displays and LEDs.

• Rugged 24VDC right angle gear motor.

•Heavy duty push buttons for everyday industrial use.

• Jog feature for positioning nozzle before welding procedure begins.

• Three-year warranty on parts and labor.
