W1009400 - ESAB ET 301i AC/DC TIG/Stick Inverter Welder

Precision TIG Performance for All Materials

The ESAB ET 301i AC/DC (Part Number W1009400) represents the next generation of digital inverter technology, engineered specifically for precision TIG and Stick welding. This unit replaces the legacy Fabricator and ET 220i models, offering expanded capabilities and higher output. At its core, the ET 301i features a true square wave AC output, which is essential for breaking through the oxide layer on aluminum and magnesium alloys. Operators can fine-tune the AC balance and cleaning action to optimize penetration and bead profile while maximizing tungsten electrode life. With High Frequency (HF) start and LiftArc capabilities, arc ignition is smooth and reliable, minimizing contamination and ensuring clean starts every time.

Industrial Specifications in a Portable Package

Despite its compact size (19 x 7.25 x 13 inches), the ET 301i is a heavy-duty performer. On 3-phase power, it delivers a robust 300 Amps at 30% duty cycle for TIG welding, and 200 Amps at 60% duty cycle for Stick welding. Even on single-phase power, the machine provides a substantial 200 Amps of TIG output, sufficient for most fabrication tasks. The Stick welding mode is equally impressive, capable of running a wide range of electrodes including E6010 and E7018, thanks to adjustable Hot Start and Arc Force controls. The machine's high efficiency and power factor correction contribute to lower energy consumption compared to traditional transformer-rectifier welders.

Smart Features for Professional Welders

Efficiency is key in production environments, and the ET 301i is designed to maximize arc-on time. The integrated Tiptronic memory stores 100 parameter sets, allowing operators to instantly switch between different joint configurations or material thicknesses without manual recalibration. Advanced pulse TIG functions help control heat input, reducing distortion on thin materials and improving weld appearance. The unit also features automatic gas control to prevent shielding gas waste. With a weight of only 16.3 kg (35.9 lbs), this machine offers the ultimate combination of power, intelligence, and portability for the serious welding professional.
