Tungsten Inert Gas (TIG) welding, also known as gas tungsten arc welding, uses a non-consumable tungsten electrode to produce a weld. A variety of industries use TIG welding for high-quality welding purposes usually on thin metals, such as aluminum. Renesas' TIG Welding Controller solution is a complete DC + AC/DC TIG programmable welding control system.

System Benefits​:

  • Precise, wide range, arc-current measurement on the secondary side
  • Detection of ozone and other dangerous gases concentration
  • Isolated controller for high-side measurements/control
  • IR multi-touch HMI display, operable with gloves
  • Connected via Wi-Fi/Bluetooth® Low Energy (LE)
  • Control circuitry for water cooling (enabling compact tool)



  • High-class 230V DC + AC/DC TIG (WIG) welding machines
  • Welding machines with water cooling
