Miller’s Spectrum plasma cutters come in 5 different models, and each will provide some different features you’ll need to consider such as rated output, duty cycle, rated cutting thickness, the recommended generator power, and the plasma cutter’s weight. Here’s a look at some of the specs for Miller’s latest plasma cutters on sale and how they stack up to each other.
Miller Spectrum 375 X-TREME Plasma Cutter
Miller Spectrum 375 X-Treme Plasma Cutter can cut up to 3/8" thick mild steel and is portable enough to go anywhere at only 19 lbs. It has incredible versatility with the dual voltage MVP 120/240 volt adapter plugs. Perfect for light fabrication setting or out on the field. It can be powered off of a capable engine driven welder/generator. If you're looking to upgrade from an outdated cutting torch outfit, this is a great option.
Miller Spectrum 625 X-TREME Plasma Cutter
If you need a bigger jolt of power and a longer duty cycle, then a 625 X-TREME plasma cutter will be your best bet for a machine that can handle 5/8” mild steel and 1/2” stainless steel. It’s also quite light, weighing in at 21 pounds. This may be the best value and greatest versatility for a plasma cutter since you can cut more and take it just about anywhere, while the next model up
is over twice the weight.
You’ll be able to run the 625 X-TREME at 40 amps with 140 volts and a 50% duty cycle that will keep you at your welding set up with minimal interruption for cooling down. You’ll get a lot of power and time on task with this top of the line machine that is one of the newest additions to Miller’s Spectrum plasma cutter line.
Miller Spectrum 875 Plasma Cutter
This heavy duty plasma cutter delivers the most power and the highest cut rating available from the Spectrum line. You’ll be able to slice through mild and stainless steel that is just shy of an inch thick and aluminum as thick as 5/8” is well within its capabilities. Best yet, you’ll get 60 amps of cutting power with a 40-50% duty cycle.
