907770 - Miller CST 282 Stick/TIG Welder 208-575V Tweco

Miller CST 282 Stick/TIG Welder Overview

The Miller CST 282 Stick/TIG Welder (907770) is a powerhouse of portability and performance, engineered specifically for the rigorous demands of the construction and pipe welding industries. Weighing in at a mere 34.6 pounds, this machine is 20% lighter than its predecessor, making it exceptionally easy to transport around complex jobsites, scaffolding, and remote locations. Despite its compact footprint, it delivers a robust 280 Amps of output, providing the power necessary for heavy-duty applications.

At the core of the CST 282 is Miller's patented Auto-Line™ Technology. This advanced feature allows the power source to connect to any primary input voltage ranging from 208 to 575 volts, single- or three-phase, and 50 or 60 Hz. The machine automatically calibrates to the input power with no manual linking required, eliminating setup errors and ensuring consistent performance regardless of dirty or unreliable power often found on construction sites.

Superior Arc Performance

The CST 282 is designed with the professional pipe welder in mind. It features specialized settings for XX10 and XX18 electrodes, offering both stiff and soft arc preferences to suit specific welding positions and techniques. Whether you are welding pipe root passes or filling in the flat position, the machine provides optimized arc characteristics for flawless results. The Adaptive Hot Start™ technology automatically increases output amperage at the start of a weld to prevent electrode sticking, ensuring smooth, inclusion-free starts every time.

Advanced TIG Capabilities and Safety

For TIG applications, the unit utilizes Lift-Arc™ starting, which minimizes tungsten contamination without the need for high-frequency interference. Safety is also paramount with the inclusion of a Voltage Reducing Device (VRD), which lowers the Open Circuit Voltage (OCV) when the operator is not welding, significantly reducing the risk of electrical shock. This model comes equipped with Miller's exclusive Universal Connector System featuring Tweco-style receptacles, allowing for easy conversion to Dinse-style connectors without opening the machine.
