The Cruxweld iTIG250ACDC Pulse TIG Welding Machine is a rugged, portable, and versatile dual-function (TIG and Stick) all-in-one welding machine. The unit can switch between AC or DC TIG welding, making it suitable for use with most ferrous and ferrous materials such as stainless steel, mild steel, brass, titanium, and aluminum. The pulse function of this aluminum welding machine combined with the HF start makes it the ideal choice for welders who want to perform high-quality TIG welding on very thin materials without distortion.


The Cruxweld iTIG250ACDC is designed for superior industrial performance. This single-phase TIG welder features digital inverter technology and a welding power of up to 250A, making it the top choice for welders. The modular design of the IGBT creates a highly reliable platform that is built to last for years. This machine has many features that add value to users.
One of the extremely useful features is the Advanced Pulse in AC which can greatly increase penetration while welding aluminum. It combines waveform control, AC frequency, and AC balance control to turn your welder into an advanced aluminum welder. A toggle switch can be used to change AC or DC mode, making setup quick and easy for novice or advanced users.
The iTIG250ACDC Pulse TIG Welder is versatile to meet the needs of both hobbyists and professional welders. Especially for TIG AC and TIG pulsed AC aluminum welding. High performance with a set of pulse characteristics Includes TIG welding at 250 amps AC or DC with a current range from 5 to 250 amps, as well as the stick welding function.


  • IGBT module technology improves reliability and performance.
  • High frequency (HF) starting for precise arc control.
  • A simple menu design allows you to quickly select and adjust settings.
  • Suitable for welding stainless steel, mild steel, aluminum, brass, and other materials.
  • Capable of welding very thin materials, especially aluminum.
  • The iTIG250ACDC square wave inverter enables precise welding of fine aluminum materials.
  • Excellent stick welding properties with the most common sticks (6010, 6013, 7018) available on the market.
  • Self-adjustable arc force for stable operation while under long-distance welding.
  • Easy setting of pre-flow, post-flow, start current, up and down slope time, and end current level.
