W1009401 - ESAB ET 301i AC/DC Water-Cooled TIG Welder Package

ESAB ET 301i AC/DC TIG/Stick Welder Overview

The ESAB ET 301i AC/DC is a high-performance inverter power supply engineered for precision industrial welding applications. This fully digital unit offers exceptional versatility, supporting AC/DC TIG, Liftarc TIG, High Frequency (HF) TIG, and Stick (SMAW) processes. Designed to meet the rigorous demands of modern fabrication, the ET 301i features automatic input voltage selection, allowing seamless operation on 208-230V or 460V single or three-phase power grids. This flexibility makes it an ideal choice for facilities with varying power infrastructure or for mobile repair operations requiring high-output capabilities.

At the core of the ET 301i is its true square wave output technology, which provides superior arc stability and cleaning action when welding aluminum and magnesium alloys. The machine eliminates the need for continuous high frequency, thereby extending tungsten life and reducing electromagnetic interference. Operators can fine-tune the arc with advanced balance and cleaning features, ensuring optimal penetration and bead profile. The unit boasts a substantial output range, delivering up to 300 Amps for TIG welding (3-phase) and 200 Amps for Stick welding, making it suitable for a wide array of material thicknesses.

This specific SKU (W1009401) is a comprehensive package designed for immediate productivity. It includes the power source, a dedicated water cooler, a robust trolley with a cylinder rack, and a high-capacity 300 Amp water-cooled TIG torch. The inclusion of the Tiptronic memory function allows users to save and recall up to 100 specific welding parameters, significantly reducing setup time for recurring jobs. With a robust aluminum case rated to IP23S standards, the ET 301i is built to withstand harsh industrial environments while maintaining a lightweight profile of just 16.3 kg for the power source itself.
