MATRIX X AC/DC’s are high efficiency TIG AC/DC inverter power sources, studied to satisfy the most advance and sophisticate request in the TIG welding market.
MATRIX X AC/DC’s are standard equipped with the new X VISION interface, simple and complete, for the total control and monitoring of all the welding parameters.
Their excellent characteristics, coupled with the high technology of the digital control, allow a perfect stability of the welding arc, granting high performance TIG welding in the more sophisticated industrial applications and maintenance.
MATRIX X AC/DC’s enable TIG welding of all metals including Aluminium and its alloys and they also offer excellent performance in MMA welding with the most difficult basic and cellulosic electrodes.
The single phase MATRIX X220 AC/DC, thanks to the PFC, optimizes the amount of energy consumption by allowing the use of this powerful power source, without problems, with 16 A fuse mains and power generator sets.

Innovative spot welding device to achieve precise and safe joining with a minimal thermal input. “Multi-coldTACK” function grants cold spotting in a rapid sequence, thus further widening the benefits of the single spot. Thanks to “Perfect-Point” function, coldTACK allows to obtain the most precise spot positioning.

RCT – Running coldTACK

RCT is the acronyms of Running coldTACK; indeed, the TIG RCT process allows to benefit of all the coldTACK advantages, by repeating the single coldTACK point in a continuous way, in order to achieve a cold and perfect welding seam. Using TIG RCT the welding seam is much colder in comparison to the one achievable with Pulse TIG and it represents the ideal solution to weld thin materials with a very low heat transfer. TIG RCT is a direct current process not available in AC welding.


  • DYNAMIC TIG – Square wave: high arc dynamics for all applications.
  • SOFT TIG – Sinusoidal wave: smoother and softer with reduced noise, ideal for medium thickness.––
  • SPEED TIG – Mixed wave: optimal penetration at high welding speed and low consumption of the electrode.
  • COLD TIG – Triangular wave: low heat transfer with reduced deformation, ideal for small thickness.


Possibility of independently adjust both current time and its amplitude while staying in either positive or negative polarity, by offering a perfect control of penetration and arc cleaning with a drastic reduction in lateral undercuts.

VRD Voltage Reduction Device

VRD device reduces the open circuit voltage to values below 12 V, by enabling the use of the machine in highly hazardous environments for the operator’s maximum safety.

PFC – Power Factor Correction (Cos f=1)
The wave shape of the current drawn from the mains is made sinusoidal by the PFC device with a consequent total lack of harmonic disturbances in the mains and consumption optimization, which enables to utilize the power source at full range on a 16 A fuse.
