Torch Height Controller

Accurate control of Torch to work distance be it Cutting of Welding, plays very important role for the quality of the end result of the process.

Torch Height Controller (THC) also know as Arc Voltage Controller (AVC) is the device which maintains the arc gap between the torch & the work piece.

Stepper motor driven vertical slide with motor driver & the controller allows the torch to move up or down depending upon the parameters set.

Arc voltage which acts as a Feedback to the controller as reference voltage, allows operator to set the Torch to Job gap as per the process & the quality requirement.

Arcraft Plasma has introduced Digital model DigiTHC100

Features of the DigiTHC100 are..........

• Suitable for welding processes like TIG, Plasma welding, PTA or Powder plasma welding.
  
• Suitable for Plasma Arc cutting.
  
• Wide range of Arc voltage acceptability.
  
• Well protected from the High Frequency interference.
  
• Piercing program for plasma cutting.
  
• Programmability in terms of Arc Voltage or Arc Gap distance.
  
• Independently adaptable to any Plasma cutting or Welding power source
  
• Independently adaptable to CNC profile cutting machine.
  
• Independently adaptable to Welding Automation.
  
• Initial Height Sensing (IHS) comes in handy to pre-adjust the required gap before start of process.

Advantages of DigiTHC100

Plasma Cutting

• Improvement in cut quality
  
• Improvement in consumable life upto 20%
  
• High productivity at high dimensional accuracy of cut components.
  
• Elimination of near collision condition of Torch & job.

Welding

• Uniformity of weld beads
  
• Controlled weld heat input eliminates chances of higher percentage of dilution, lack of penetration, undercut etc.
  
• Easy adjustment of weld pool fluidity depending upon the application of weld & welding process by maintaining the
• constant gap & hence the heat input.
  
• Dramatic improvement in weld aesthetics.
