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
XT40 Torch
Ergonomic handle with unique no-slip grip, thumb guide and finger contours help prevent operator fatigue while the flexible cable makes maneuvering easy. Now comes with the new ultra flexible Quick Connect work lead with smaller heavy duty clamp.  Learn More
Auto-Line™ and MVP™ (multi-voltage plug) Adapters
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™) Adapters allow connection to 120 or 240 V receptacles without tools—choose the adapter 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 and gouging performance.
Portable in the shop or at the job site—at 21 pounds 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 Plug Adapters, consumable box, as well as gloves, eye protection, etc.  Learn More

Reviews & Ratings

Rated 4 out of 5 by from Really good cutter, bad bad storage box Would have been 5 stars if the box was useful. I love the cutter. It is powerful, small, can plug it in anywhere. I hardly ever use it. I have owned it for 2 years and avoid using it. I try to use a die grinder with carbide burr instead, or a body saw, or a band saw or saws all. If you are wondering why its because of the black storage box. The black plastic storage box is awful. I used it today. The cutter does a great job. Used it to cut out a small .5" x 1" rectangle is 1/8" hot rolled plate. It took just a minute or so to make the cut. Afterwards I screw around for 20 minutes trying to get the cutter and cords back into the box. That's why I avoid using it. Too much screwing around to put it away. Whoever designed the box designed it to put factory wrapped cords and hoses in for shipping rather than for a real workman to use. It needs a box intended for shop use. I also have a Maxstar 150 STH. Owned it for about 2 years. Same story but worse, has even more stuff to get back in the same size box. I have used it one time only. I use my Dynasty 200DX instead and bring the work to it. I purchased portable tools for use as portables not to sit on a cart. The Spectrum 625 and Maxstar 150 defeat that portability because of the poor box design.

Rated 1 out of 5 by from Complete disappointment After spending $1800 on a brand new, out of the box tool, I hook it up, turn it on, and it won't work. I've spent half a day trouble shooting and no luck. Apparently I'm not the only one who's had the problem I'm having. There's plenty of posts on the web with the same issue. So far the most reliable is to take it in to be fixed. This is the first miller product I've purchased. I always thought they were top of the line. I no longer have that perception.

Rated 5 out of 5 by from great machine, fast delivery Very happy with this plasma cutter, I bought it for my son who is a junior in High school ( taking metal fab in voc school), he said it is far superior to the machines they have in school. I was impressed with how easy it is to use and set up having never used one before.

Rated 5 out of 5 by from assume machine I run this off my Bobcat 225 or my shop 220v. Cuts great and the weight/size of it is much smaller than my older Hypertherm. Haven't tried the 120 yet but I'm sure it's fine.
