MODEL 3
ARC VOLTAGE CONTROLLER
WITH ARC GAP SETTER

Motorized slide is pictured mounted on a
lathe and WITHOUT the leadscrew guard.
Shown with optional wire feeder.
As shown on the attached pdf.

Use with either GTAW (TIG) or Plasma (PAW) Welding
processes to maintain a steady arc length by monitoring the
arc voltage and moving the torch up or down to compensate
for irregular surfaces. Benefits are:

Max welding current 300 Amps
Available in 50 amp and 100 amp versions in order to use the broadest scale of sensitivity at lower amperages
Max. Arc Voltage 70V
