ESAB Buddy ARC 630i ARC/TIG Heavy Duty Inverter Welder | 0700300905 .
The ESAB Buddy ARC 630i is a high-performance, industrial-grade inverter welding machine engineered for continuous 24x7 operation. Designed for MMA (Stick) welding, Scratch TIG and Air Carbon Arc Gouging (A-CAG), this robust power source delivers up to 630 amps, making it ideal for heavy fabrication, construction and industrial maintenance applications.
Built with advanced IGBT inverter technology, the Buddy ARC 630i ensures excellent arc stability, improved energy efficiency and consistent welding performance. Moreover, it maintains stable operation even when using long welding leads with E6013 and E7018 electrodes. Thanks to its wide operating window of 20 – 630 A and wide mains voltage tolerance of 400 V (-15% to +20%), it adapts easily to demanding site conditions.
The machine features user-friendly controls, including adjustable Arc Force and Hot Start in MMA mode, as well as a process selection switch for MMA and Scratch TIG. In addition, integrated protection systems guard against mains over-voltage, under-voltage and overheating, thereby enhancing reliability and operational safety.
Its durable industrial construction allows it to withstand harsh environments such as cement plants, process plants and large construction sites. At the same time, the compact inverter design improves efficiency while maintaining powerful output performance.
