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

Reviews & Ratings

Rated 5 out of 5 by from Spectrum® 375 X-TREME™ plasma cutter I love this machine. All i own is Miller would not buy any thing else. This Plasma Cutter will do anything I've asked it to do from the thinnest metal to 1/2" Material with very little trouble. Easy to pick up and take anywhere. Wish it had a handle to pickup easier.

Rated 5 out of 5 by from Spectrum 375 X-TREME I've used several different plasma cutters in the past, A very versatile machine this one is the easiest one to use yet. I've always been a miller fan, but I'm not afraid to buy another brand if it suits my needs better, well I'll have this one for a very long time!! I'd recommend it to the novice and even the professional.

Rated 5 out of 5 by from Great entry level product. After talking to several welders I got this machine along with a Millermatic 180 welder for prototype development and it has exceeded my expectations. Great product.

Rated 5 out of 5 by from Good things come in small packages This plasma cutter is a great little unit . I have cut metal heavier than 3/8 with good results and very easy to use . I recommend this Miller plasma.

Rated 5 out of 5 by from So much better than using a torch Light weight, very easy to use. I like that you have little work to clean up after cutting. The adapters lets use choose what voltage you want.

Rated 5 out of 5 by from Works Great Small, lt weight, dynamite in a small package. All employees love it. Wish I had purchased a long time ago.

Rated 5 out of 5 by from Easy to use, small, lightweight, and works Simple to set up and it works. I use compressed air and use the Miller inline filter at the machine. I also have a water filter at the compressor. My only complaint is that the ground cable is ridiculously stiff for a small portable unit. A more flexible cable, like the one on my Miller welder, is much easier to use. The MVP feature allows me to use either 240V or run less expensive 12 gauge 120V extension cords when the work is too far from the barn to plug directly into the 240V outlet.

Rated 5 out of 5 by from Great plasma!! I just use it around the garage. It takes a little bit to get through 1/2 plate but it still 1,000,000 times faster than a cut off wheel.

Rated 5 out of 5 by from Excellent and Precise Metal Cutting Made Simple The Spectrum ® 375 X-TREME™ Plasma Cutter is a must have for metal working. It's very simple to use and easily makes complicated cutting easy and clean. The metal you are cutting does not get as hot as cutting with a torch so the metal does not warp. I high recommend this plasma cutter!

Rated 5 out of 5 by from very easy to set up and use if you have your own compressor =this is the absolute ,top of the line way to go.......have had others and they did a good job , ,,but they do not get any better than this model////////

Rated 4 out of 5 by from Valuable shop tool Our first P/C lasted over 30 years with no problems. We bought this one 12 months ago and it has been in for repair twice for a total of 60 days. The whip seems to be a bit touchy. If several people are going to be using the P/C, you may want to check out a different model.

Rated 5 out of 5 by from Cuts cleaner than oxy-accetylene There's a little learning curve with a plasma cutter, mostly to do with thickness settings. Once you get past that, it's a breeze. The burrs left from the cut usually just scrape off. You need an air supply for this unit. If that's not a problem, it will serve you well. Nitrogen tanks work in locations where air isn't available. The machine runs on two voltages, 110 and 220 single phase. The 220 works best; 110 trips breakers in my shop. For those of you who lack a steady hand, a straightedge or roller guide will do the trick. Free handed cutting takes practice. The machine is about the size of a toaster and not too much heavier, making it quite portable. The 375 Extreme has 12 feet of torch cord instead of ten. The extra two feet of cord has been helpful more than once. I am pleased with this machine.

Rated 4 out of 5 by from Great product for my needs. I love that it automatically adjusts to the different voltages. And that it can be used on 110 and 220. This makes it very portable for my needs. The cut quality is exactly what you would expect from this Miller...Exellent.
