Spectrum® 375 X-TREME™ with XT30 Torch
30 Amps for 3/8 in. mild steel capacity, XT30 torch with ergonomic handle and flexible cable, Auto-Line™ and MVP™ Plugs make this 19 lb unit the most portable plasma cutting system in the market!
Rated Cutting Capacity
The rated cutting capacity is based on traveling approximately 15 inches per minute to achieve a steady, precise cut. This is the key rating that should meet or exceed your typical cutting thickness requirements.
Auto-Line™ and MVP™ (multi-voltage plug)
Auto-Line provides state-of-the-art flexibility to the end user. The Auto-Line circuitry automatically connects to 120–240 VAC, single-phase power, 50/60 Hz, without removing the covers to relink the power source. Miller’s multi-voltage plug (MVP™) allows connection to 120 or 240 V receptacles without tools—choose the plug that fits the receptacle and connect it to the power cord.
Automatic Air Regulation
The unit automatically compensates for input pressure variation to provide constant recommended torch pressure for optimum cutting performance.
XT30 Torch
Ergonomic handle with unique no-slip grip, thumb guide and finger contours help prevent operator fatigue while the flexible cable makes maneuvering easy.
Auto-Refire™
Auto-Refire™ Technology provides ultimate customer convenience by automatically controlling the pilot arc when cutting expanded metal or multiple pieces of metal. The pilot arc will switch in and out as fast as needed when cutting expanded metal and provides maximum power for cutting thicker metal—all automatically! No need for manual re-triggering which reduces user hand fatigue.
Portability
Portable in the shop or at the job site—at 19 lb the shoulder strap allows the end user to easily move from location to location.
Wind Tunnel Technology™ and Fan-On-Demand™
Wind Tunnel Technology - internal air flow that protects electrical components and PC boards from dirt, dust, debris…greatly improving reliability. Fan-On-Demand cooling system only operates when needed. In dirty or dusty environments, this feature reduces the amount of airborne dust/dirt pulled through the unit. See how it works.
