Product Description

Micro Plasma Welding Machine



Plasma welding is very similar to TIG as the arc is formed between a pointed tungsten electrode and the work-piece. However, by positioning the electrode within the body of the torch, the plasma arc can be separated from the shielding gas envelope. Plasma is then forced through a fine-bore copper nozzle which constricts the arc. The micro-plasma arc can be operated at very low welding currents. Micro-plasma is traditionally used for welding thin sheets (down to 0.1 mm thickness), and wire and mesh sections, tubes and various delicate assemblies and parts with great precision and reliability.


  • IGBT inverter based with integrated HF start system. PLC sequencer for automatic operation and integration with welding lathe / positioner / turntable / linear welding fixture etc.Wave Correction Technique - Milli second square wave correction technique for fast correction of welding current irrespective of arc length or input voltage variation.
  • Stable Arc - PLL based closed loop system for highly stable arc.
  • Low Metal Thickness - The Machine is capable of welding metal sheet of capability from 10 microns to 3mm thickness.
  • Low distortion and less tension.
  • Pulsed current at high frequency, up slope and down slope for current provided.
  • Manual as well as Robotic Torch - A manual torch and a machine torch available for manual or mechanized operation.
  • Programmable - The machine is fully programmable with built in welding cycle timer in the auto mode.
  • Digital Version - Digital version available on demand with computer interface for automatic welding with turntable / welding lathe / linear welding automation as required.
  • Interface provided for welding automation.
  • Heat transfer type refrigerated water cooling system.
