SpreadarcOscillator

Automatic Welding Head Oscillator

The Spreadarcis designed to oscillate an automatic welding head for continuous welding at high duty cycles.

The Spreadarcis compatible with the NA-3, NA-4, NA-5 and Power Feed10A 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.

Advantage Lincoln

Arc length remains constant during oscillation to provide a more uniform penetration.

Dwell timers provide delay periods at the 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.
