The Miller CST™ 280 (SKU: 907563) is a premier solution for industrial construction, pipe fabrication, and maintenance operations requiring a robust yet highly portable welding power source. Engineered to deliver 280 Amps of superior Stick (SMAW) performance, this machine is capable of handling electrodes up to 3/16-inch in diameter, making it ideal for structural steel and pipe applications. Weighing in at just 41 lbs, the CST™ 280 is designed to be easily transported around job sites, from ground level to high-elevation scaffolding, without the need for heavy lifting equipment.
This specific model comes equipped with a digital meter, providing operators with precise amperage readouts for critical welding procedures where adherence to specifications is mandatory. The unit features Dinse-style connectors for secure and efficient cable management. One of the standout features for industrial procurement is the machine's input power flexibility. It accepts a wide range of input voltages (208-230/400-460 V) and operates on both single- and three-phase power, ensuring compatibility with the varied power supplies found in plants and field sites.
Reliability is central to the Miller CST™ design. The simple voltage changeover switch is easily accessible, reducing setup time and minimizing the risk of connection errors. For TIG applications, the Lift-Arc™ start provides contamination-free arc initiation without the use of high frequency, which is essential in sensitive electronic environments. Backed by Miller's True Blue 3-Year Warranty, this machine represents a secure investment for fleets and individual contractors alike.
