nd ideal for hardfacing applications.
T
he 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.

• Arc length remains constant during oscillation to provide a more
uniform penetration.
• Dwell timers provide delay periods a
t 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.
