Product Code : PW 200
Brand Name : Arcraft Plasma
Product Description


  • IGBT inverter based with analog/digital controls & integrated HF arcing system that tremendously increases its efficiency and switching characteristic.
  • Sensitivity - Less sensitivity to changes in Arc length.
  • Cool Operation, Long Life - Recessed electrode reduces the possibility of tungsten inclusions in the weld and can substantially increase the period between electrode dressings resulting in increased life.
  • High Productivity - Weld in a single pass up to 6 mm plates in square butt position and 10 mm plates in only two passes.
  • Low degree of Deformability - Keyhole mode of welding gives smaller heat affected zone resulting in reduced strength loss at the joint for heat treated metals, promotes less grain growth which gives better ductility.
  • Less Embrittlement - Reduced weld time and effective gas shielding results in less embrittlement by carbides and complex inter-metallic compounds for stainless steel and super alloys.
  • Less Residual Stress - Equalization of distortion stresses results in less residual stress.
  • Reduced Porosity - Less filler metal required in keyhole mode significantly reduces porosity, lowers cost of welding with faster welding speed. 
  • Less Power Consumption: Advanced welding system as compared to TIG welding, Plasma Welding Machine gives higher amount of usefull heat energy at 50% less power consumption than TIG welding.
  • Narrow and Deeper Penetration: Highly constricted arc formed by Plasma which is covered by shielding gas results in narrow & deeper penetration.
  • Low heat affected zone.
  • Excellent fluidity of weld pool.
  • Better weld metallurgy.
  • Advantages over TIG welding.
  • Increase in welding speed by 25 to 30%.
  • Narrow Heat Affected Zone (HAZ).
  • 100% penetration possible in single pass.
  • Saving in filler wire upto 80%.
  • Easy to automate.
