W1009300 - ESAB ET 220i AC/DC HF TIG/Stick Inverter Welder

Precision AC/DC TIG Welding in a Portable Package

The ESAB ET 220i AC/DC HF is a revolutionary step forward in portable welding technology, designed to meet the rigorous demands of professional fabricators who require flexibility and precision. This high-output inverter power supply is engineered for both Stick and TIG welding, offering a comprehensive solution for joining all weldable materials, including aluminum, magnesium, stainless steel, and mild steel. At the heart of the ET 220i is an embedded microprocessor with full digital controls, ensuring stable arc characteristics and repeatable results every time you strike an arc.

One of the standout features of this unit is its true square wave output. This advanced waveform technology provides superior cleaning action and penetration control when welding aluminum alloys, significantly extending tungsten life and improving weld quality. The machine eliminates the need for continuous high frequency during AC welding, reducing interference with sensitive electronics nearby. Operators can easily switch between High-Frequency (HF) start and Liftarc TIG start depending on the application environment, ensuring reliable ignition without tungsten contamination.

Versatility is key with the ET 220i. It boasts expanded input voltage capabilities, accepting 208-230V or 460V input on either single or three-phase power. This flexibility allows the machine to be used in a wide variety of locations, from industrial manufacturing plants to remote job sites powered by generators. Weighing in at just 29.5 lbs (13.4 kg), the unit is enclosed in a robust aluminum metal case that protects internal components while remaining light enough to carry by the convenient handle. Whether you are climbing scaffolding or moving between workstations, the ET 220i travels with you effortlessly.

The user interface is designed for efficiency, featuring Tiptronic memory functions that allow operators to save and recall their favorite welding parameters. This reduces setup time for recurring jobs and ensures consistency across shifts. Additional features like automatic downslope, pulse control, and automatic gas management further enhance the operator's control over the weld puddle, making this machine a top choice for precision applications in aerospace, automotive, and general fabrication.
