The Miller STH 270 is a portable, water-cooled DC TIG welding machine designed for both shop use and jobsite mobility. Weighing approximately 24 kg (52.9 lb.), it is equipped with a black protective frame and wheels, facilitating easy transport between locations. The machine features a robust blue casing with a black handlebar on top for enhanced mobility.
This inverter-based power source offers a simple, user-friendly operator interface that includes a digital display, multiple control buttons, and a central control knob, providing only the necessary controls in a compact design. The front panel also includes several connection ports for welding cables and accessories. The unit supports two types of arc starts: Lift-Arc™ start, which enables TIG arc initiation without high frequency or tungsten contamination risk, and HF start for non-contact arc initiation that avoids contamination of tungsten or the material.
Built-in pulsing capabilities allow operators to select from four fixed pulse frequencies to suit various applications. The machine delivers 270 A at 30.8 V with a 40% duty cycle, powered by a 400 V, 16 A, 3-phase, 50/60 Hz electrical supply.
Additional features observed include a black tray on top for tool or accessory storage and coiled welding cables properly stored on the side. The machine has visible warning labels with pictograms on the side panel for safety guidance. Both the frame and wheels show normal signs of use but no damage, indicating good physical condition with minor surface wear overall. Power plugs in orange and red colors are connected to cables near the front and side panels, respectively, enhancing connectivity options.
Overall, the Miller STH 270 combines portability, ease of use, and versatile TIG welding functions suitable for various professional welding tasks.
