The Miller is rated at 30 amps and can cut mild steel, stainless steel, or aluminium. Additionally, the auto-line technology and MVP adapters allows the unit to work with both 120V or 240V input power. The XT30 torch with ergonomic handle and flexible cable makes the cutting system most user-friendly. Despite being a fair-sized tool, it is quite light to transport.

The Great Feature That Makes IT Great -
Rated Cutting Capacity
Miller Spectrum 375 has a cut rating of 3/8 inch at 18 IPM which refers that you will achieve a smooth, steady cut at 18 inches per minute. This rating exceeds your typical cutting thickness requirements. This cutting capacity makes the tool ideal for most fabrication, HVAC applications, maintenance as well as home workshop or hobbyist application.
Spectrum removes your concern whether you have the correct machine for the shop or job. The unit features Auto-line and MVP (multi-voltage plug). The MVP enables the tool to switch between 120V and 240V easily. You just need to select the right plug for the receptacle and plugs it into the cord.
Auto-Line Technology enables the unit to adapt automatically to a wide range of voltages. Spectrum 375 accepts input voltage ranging 120 through 240V, 50/60 Hz. You don’t need to remove the covers to relink the power source.
Line Voltage Compensation (LVC)
Miller 375 plasma cutter features Line Voltage Compensation that allows the input power to fluctuate +/- 10 % without affecting the cutting performance. This is really an important feature if you plan to use the cutter in a location subject to power fluctuations.
Automatic Air Regulation
This feature allows the unit to automatically adjust the input pressure variation to ensure constant recommended torch pressure. Thus, it provides the optimum cutting performances.
Auto- Refire Technology enhances the user convenience by automatically controlling the pilot arc. With the change of the working surface, the tool automatically switch in and out as fast as needed. You don’t need to re-trigger the arc manually. Hence, this technology reduces user hand fatigue.
Spectrum 375 comes with XT30 Torch that features ergonomic handle with unique no-slip grip, finger contours and thumb guide. These features ensure user’s comfortability and prevent fatigue. Its flexible cable makes the tool easy to maneuver.
Wind Tunnel Technology And Fan-On-Demand
Spectrum 375 features Wind Tunnel Technology and Fan-On-Demand. The internal air flow protects internal components from abrasive dust and particles by blowing them through a tunnel. The tunnel runs down the center of the unit. The device also comes with a fan that allows you to run when needed. The fan reduces the amount of airborne dust in the air and thus maintain the performance of the tool by running the cooling system when needed. In addition, this also helps to save utility bills.
Protective And Durable X-Case
Miller Spectrum 375 comes with a hard plastic made X-case. It provides protection during storage and transport. The case is spacious enough to hold consumable box, MVP plugs, gloves and eye protection.
