Miller Spectrum 375 Plasma Cutter Features
Rated Cutting Capacity
The Miller Spectrum 375’s rated cutting capacity of approximately 15 inches per minute is the industry cutting thickness requirement that gives its user a steady and accurate cut.
XT30 Torch
It comes with an XT30 Torch that features a non-slip, ergonomic grip, finger contours, and thumb guide to help reduce user fatigue and a flexible cable that allows for easy maneuvering.
Auto-Line Technology
Its Auto-Line circuitry automatically connects to 120–240 VAC, single-phase power, 50/60 Hz, without you having to relink the power source. It provides extreme flexibility by allowing you to switch from one voltage to the other quite easily.
MVP Technology
The MVP or Multi-Voltage Plug technology allows connecting to 120 or 240 V receptacles without requiring tools; you just have to choose the plug that fits the receptacle and attach it to the power cord.
The line voltage compensation feature also allows you to use the cutter in places where there are power fluctuations within a range of +/-10% without affecting its cutting performance. You can still achieve that clean and precise cut, and enable you to get your work done on time without being bothered by the fluctuating power supply.
Auto-Refire Technology
The Miller Spectrum 375’s Auto-Refire Technology provides the utmost convenience for you by controlling the pilot arc to switch in and out as fast as needed, mostly when used on multiple pieces of metal or expanded metal. It gives you supreme power automatically, thereby reducing hand fatigue. No more manual re-triggering.
Wind Tunnel Technology
Its Wind Tunnel Technology protects the PC boards and electrical components from dust, debris, and dirt by providing an internal airflow that blows them out through the tunnel that runs along the center of the unit.
Fan-On-Demand
The Fan-On-Demand cooling system lessens the amount of dust and dirt that can be pulled through the unit during use. It also prevents overheating, which adds to the machine’s longevity. The best part is that it is designed to operate only when needed, reducing energy consumption, as well.
Automatic Air Regulation
The Automatic Air Regulation feature takes care of the variations in input pressure automatically, so you always have the recommended torch pressure for excellent cutting performance. Smooth and steady is what you will always get.
Protective X-CASE
The Miller Spectrum comes in a protective, hard plastic case that keeps the plasma cutter secure during storage and transport. It also has ample space for the XT30 torch, consumables, multi-voltage plugs, gloves, and eye protection.
Extreme Portability
Weighing approximately 19 lbs., it is light enough to move from one area of your shop or job site to another with relative ease, especially with the shoulder strap included in the package.
