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.

Spreadarc

™

Oscillator

• 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.
