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.  Learn More
XT30 Torch & Quick Connect Work Lead and Clamp
Ergonomic handle with unique no-slip grip, thumb guide and finger contours help prevent operator fatigue while the flexible cable makes maneuvering easy. Comes with the ultra flexible Quick Connect work lead with smaller heavy duty clamp.  Learn More
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. The Miller 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.  Learn More
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.  Learn More
Automatic Air Regulation
The unit automatically compensates for input pressure variation to provide constant recommended torch pressure for optimum cutting performance.
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.  Learn More
Protective X-CASE™
Miller's X-CASE provides ultimate protection during transport and storage. Additional space is ideal for MVP Plugs, consumable box, as well as gloves, eye protection, etc.  Learn More
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.  Learn More

Rated 5 out of 5 by from Worth it's weight in gold! After purchasing (and returning) another vendors inferior quality plasma cutter (assured to me by that vendor to be as good or better than a Miller), I quickly realized my mistake and their lie. The Specturm 375 X-TREME plasma cutter is tremendous value, as it's cut everything I've asked of it without any problems at all. Miller has found a customer for life in me.

Rated 5 out of 5 by from Tough little machine This is my second Miller plasma cutter. The first was lost to a lightening strike so I upgraded to the 375, It's been used A LOT! It's never failed and has done exactly what's been advertised. I mainly use it on sheet metal but it's cut thicker when needed. For automotive hobby use it's hard to beat.

Rated 5 out of 5 by from How many ways can you spell "OH YEAH"? Right out of the box this product oozes quality, Screams reliability, No need to take out "plasma Cutting for dummies" This plasma cutter takes the smallest amount of knowledge and experience of the user and down right magnifies "Professional" through out the cut and project. With this having been said, It has made my confidence and passion for metal working and art explode. Gone are days of cussing and metal shear throwing. LOL my shop walls thank you! Thank you, K.B. Bynon
