OVERVIEW

Professional AC/DC TIG Welding Power

The ESAB ET 301i AC/DC is a powerhouse of precision and portability, designed to meet the rigorous demands of modern fabrication. Whether you are welding aluminum in a clean room or repairing stainless steel components in the field, this inverter-based power source delivers exceptional arc characteristics. With a maximum output of 300 Amps on three-phase power, it rivals much larger, heavier machines while maintaining a compact footprint that weighs just under 36 pounds. This high power-to-weight ratio makes it an ideal choice for maintenance trucks, construction sites, and workshops where space and mobility are premium assets.

Versatile Input Power

One of the standout features of the ET 301i is its input voltage flexibility. It automatically detects and adjusts to 208-230V or 460V inputs and operates seamlessly on both single-phase and three-phase power. This versatility ensures that you can plug in and weld virtually anywhere, from a residential garage to a heavy industrial plant, without worrying about power compatibility. The unit is also generator-friendly, requiring approximately 13 kW for full output, making it a reliable companion for remote field work.

Advanced Digital Control

The ET 301i puts total control at your fingertips. The fully digital interface allows for precise adjustment of all welding parameters, including pulse frequency, downslope, and gas post-flow. The Tiptronic Memory System is a favorite among professionals, allowing you to store and recall up to 100 distinct welding programs. This feature eliminates setup time for recurring jobs and ensures consistent weld quality every time you strike an arc. For aluminum welding, the machine offers true square wave output with adjustable balance and cleaning, extending tungsten life and producing aesthetically pleasing, high-quality welds.

Rugged and Reliable

Built to withstand the tough conditions of industrial environments, the ET 301i is housed in a durable aluminum case that protects internal components from impact and debris. It is backed by ESAB's 3-year power source warranty, giving you peace of mind that your investment is protected. Whether you are performing critical aerospace welds or general maintenance repairs, the ESAB ET 301i AC/DC provides the reliability and performance necessary to get the job done right.
