Lincoln Idealarc TM-300/300 Arc Welder, 300A, 60% Duty Cycle, AC/DC, 1PH, 230/460V

The Lincoln Idealarc TM-300/300 is a heavy-duty industrial arc welding power source designed for both AC and DC welding processes. This versatile machine is engineered to support a wide range of applications, including stick (SMAW) and TIG (GTAW) welding. Operating on single-phase power, it typically supports input voltages such as 230V or 460V at 60Hz. The unit features a rated output of 300 amperes at a 60% duty cycle, providing consistent performance for demanding fabrication tasks. The output current is adjustable across a broad range, allowing for precise control over the welding arc to accommodate different material thicknesses and electrode types. Built with a rugged cabinet design, the machine incorporates a large, easy-to-read current scale and a polarity switch for quick transitions between AC, DC positive, and DC negative outputs.
