The ESAB TIG 300i is a compact yet heavy-duty IGBT inverter-based TIG and MMA welding machine designed for industrial fabrication, pipe welding, repair, and maintenance applications. Equipped with High Frequency (HF) Arc Start, it provides smooth arc ignition and exceptional welding performance for both TIG and Stick welding.
Advanced welding controls including Pre-Flow, Post-Flow, Start Current, End Current, Up Slope, and Down Slope enable precise heat control, resulting in superior weld quality on stainless steel, mild steel, and alloy materials.
With a robust duty cycle, energy-efficient inverter technology, and comprehensive protection against over-temperature, under-voltage, over-voltage, and single-phasing, the TIG 300i is built for continuous industrial operation.
