Torch Height Controller

Torch Height Controller (THC) is also known as Arc Voltage Controller (AVC) it 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.
