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

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

Rated 1 out of 5 by from No So Good I have only used it a few (literally a handful of times - ie. not many hours of use) and the pressure switch seems to have gone bad. Either the pressure switch of the control board, either way my machine is down! Not good since I'm trying to cut hurricane shutters in preparation for the next potential big storm.

Rated 1 out of 5 by from The best way through your money away After 2 weeks from purchase this new cutter just stop working. I try to return the cutter to the Dealer but they send me to the repair center (no body buy a 2,000 plasma cutter to take it to the repair center) On the repair center say is the main board and is a very common defect.

Rated 1 out of 5 by from Not trustworthy or durable My shop is "blue" I've got a MM210, MM252 with a Spoolmatic 30A. A syncrowave 351 and a maxstar 150. When the time came to upgrade my old thermal dynamics dinosaur, I didnt hesitate to buy the Spectrum 625 xtreme. I wish I had. I love my miller welders, but the plasma cutter has been a big mistake. Yes, it will cut 5/8" however, too slowly to consider it productive. 1/2" is slow even with new consumables. The consumables go quick! much quicker then my old dinosaur machine. I have refrigerated and filtered air at my shop, but still can't seem to get much life out of them. After just over a year the machine stopped working. After troubleshooting the issue I found what the issue was. Right after the strain relief on the torch the small gauge wires had broken that control the "cup saftey" micro switch on the head of the torch. After I found the pinout I was able to just jump the two wires to fool the machine. I did this for a week as I rely on and use the machine everyday. In the mean time I ordered a new 20' XT40 torch. That was in the end of January of 2017. Now it is August and 2 days ago the same thing has happened. Luckily its still covered by millers warrantee of 1 year. The extreme downside is I need to use the machine and I cannot mutilate this one in the meantime as I want to get the warrantee covered. I am disappointed in this product and feel as though miller needs to revise the type of wires they use in the torch cable as well as how rigid the cable sheething is. I also found many similar experiences after searching. Hope this helps others, I will begin the search for the replacement.

Rated 5 out of 5 by from Beyond Awesome!! Use this thing every day to cut a variety of things. Aluminum, copper, steel, stainless, rusted/painted stuff.. it has no problem!! it says its rated for 5/8 steel but really I used it on some 1" thick pipe and it cut straighter than I could with a cutoff wheel.. Even if you're limited to 120v you can still cut 1/4 no problem. This little dude Preforms way better than any other 60lb+ machine that I have ever used. Consumables are expensive but hey it's worth it. The box is strong it has taken the abuse getting thrown around and like others said it's tight to fit the cords in but if you're nice and tidy and take care of it, everything fits in smooth. Its about a year old and has never let me down.

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.
