Arc Length Controls

A Jetline Arc Length Control assures consistent, high quality welds on AC or DC applications by controlling the arc gap (arc length) between the torch tip and work surface. The control measures arc voltage and compares the measurements to the operator setting. It maintains the set arc length by moving the torch up or down as required via a motorized slide. 

  • Regulates the welding voltage resulting in precise, repeatable procedures using GTAW or PAW
  • User-friendly software interface
  • Automatically senses the welding arc voltage to maintain the arc length at the predefined distance within an accuracy of ±0.1 volt
  • Servo drive controls the torch height
  • Helps to maintain constant weld penetration on uneven surfaces
  • Automatically sets the starting arc gap with GTAW
  • Standard 6” (150 mm) actuator stroke
  • Actuator can handle up to 40 lb (18 kg) at torch mount
  • Compensates for electrode wear
  • Can be integrated with other Jetline controls or used as a stand-alone control
  • The ALC-701: easy to integrate with other controls
  • AC Enhancement Facility for AC GTAW applications


  • Optional actuator stroke of 1” (25.4 mm), 4” (100 mm), or 12” (300 mm)
  • Remote pendant control available
  • Cross slides available for torch positioning
