Esab 0445-100921 Tig Stick Welding System 300A

Product Description

The ESAB 0445-100921 is a portable TIG and Stick welding power supply built for demanding field and shop applications. Weighing 33 pounds, the Renegade ET 300iP delivers 300 amps at 40 percent duty cycle while maintaining a compact, rugged form factor suited for extreme environments. The unit automatically accepts single- and three-phase input power from 208 volts to 460 volts, requiring no manual switching. Output range spans 5 to 300 amps, providing flexibility across a wide range of TIG and Stick welding tasks. Licensed welders and skilled trade professionals working in industrial, construction, and maintenance environments are the primary installers and operators of this system.

The Renegade ET 300iP is designed for both in-shop use and remote jobsite deployment. Its three-handle design allows easy transport through manholes and other restricted-access areas. The pulse HF TIG function covers a frequency range of 0.1 to 1000 Hz, supporting precise arc control, improved penetration, and faster travel speeds. The package ships with a 10-foot input cable, a shoulder strap, and two male 50mm OKC connectors. Air-cooled and water-cooled torch packages are available separately for different process requirements.
