Miller Spectrum 875 Auto-Line Plasma Cutter

miller_spectrum.jpgWatching a plasma cutter in action is an impressive thing. We first saw one on a job site where we had to cut away a section of 1/4" stainless steel plate. It was far too big of a job for a recip saw and we couldn't get a band saw in the cramped conditions (and who knows if that would have even worked), so we called on the metal guys and their plasma cutter. The process took about 1/2 of a day, 7/8 of which consisted of the electrician wiring a plug, and everyone else setting up protection so nothing would catch on fire.

The actual work was done in about 15 minutes of light, sparks, and dropping blobs of hot metal. The ease with which the cutter diced the stainless was pretty intense and left us in awe of these 'anti-welders.'

So it was cool to hear that Miller has just released a new plasma cutter that makes the whole portability factor a whole lot easier. it's got a feature called Auto-Line which means it can run on a variety of input voltages without compromising the cutting quality. It can also handle changes in power input (say if it's running off a generator). This translates into not needing an electrician and a much quicker set-up. Not to mention the wider variety of situations it can handle.

The Spectrum weighs about 55 lbs so it's nice and portable. It's capable of cutting metal up to 1-1/4" thick, so it should be able to handle most jobsite issues.

The Miller costs about $1950 and it's at

The press release with more information is after the jump.

Spectrum 875 Auto-Line Plasma Cutter Offers Flexibility For Manual or Automated Cutting Applications

The Spectrum® 875 Auto-Line from Miller accepts any primary input voltage from 208 to 575 volts, single- or three-phase, 50 or 60 Hz and is available in handheld and machine torch packages for mechanized plasma cutting applications.

Highlights/Key Facts

• Auto-line technology allows unit to be used in virtually any location without the need for any physical linking mechanism.

• Machine torch packages enable use in semi- and fully-automated cutting applications.

• Compact, lightweight design increases portability and frees up valuable production space.

• Spectrum 875 Auto-Line replaces Spectrum® 2050 with upgraded features and lower cost.

APPLETON, Wis., August 18, 2010--Miller Electric Mfg. Co. today introduces the Spectrum 875 Auto-Line plasma cutter. Weighing 56 lbs. and able to cut metal up to 1-1/4-in. thick (7/8-in. at a rated quality of 10 inches per minute), the Spectrum 875 Auto-Line is ideal for fabricators, contractors and businesses that require job site versatility, portability and exceptional cutting performance.

The Spectrum 875 Auto-Line seamlessly recognizes and adjusts to any input voltage from 208 to 575 volts, single- or three-phase power and 50 or 60 Hz without the need for physical linking mechanisms. The Auto-Line technology enables the unit to operate on generator power without being affected by power fluctuations during the use of other power tools.

Fit for the Field
Auto-Line allows companies to simply plug the unit in and begin cutting in virtually any shop or field environment and location. When connected to the generator power from Miller's Bobcat or Trailblazer gas engine drives, the Spectrum 875 Auto-Line provides a 45-amp output to cut steel ½-in. thick. When connected to Miller's Big Blue "deluxe" model diesel engine drives with 12,000 watts or more of generator power options, the Spectrum 875 Auto-Line provides a full 60 amps of rated output to cut 7/8-in. steel at 10 ipm.

Replacing Miller's Spectrum 2050 plasma cutter, the Spectrum 875 Auto-Line offers increased cutting power and several upgraded features, yet with a lower price tag and in a package that weighs 30 lbs. less than the 2050. Among these upgrades, the Spectrum 875 Auto-Line provides automatic air regulation, eliminating the need to manually adjust the air pressure to match the cutting application, an additional 5 amps of output power and Miller's patented Ultra-Quick Connect™ torch and work cable for the fastest torch and cable connection and removal in the industry.

The Spectrum 875 Auto-Line's Auto-Refire technology automatically keeps the pilot arc lit while cutting expanded metal or multiple pieces of metal, eliminating the need for manual re-triggering and reducing operator hand fatigue.

For fabricators who want to take plasma cutting precision to the next level, the Spectrum 875 Auto-Line is also available with an optional machine torch package for mechanized cutting applications. The machine torch package includes a barrel-style torch for attachment to an automated cutting system, and a cable kit allowing easy access to remote on/off, ok to move and voltage sensing. In mechanized applications that require very precise output consistency, the Auto-Line technology provides a smooth, reliable cut in the event of brown-outs or other primary power fluctuations.

The Spectrum 875 Auto-Line will not replace the standard Spectrum 875, which operates solely using the most common input power in fabrication environments: 230-volt single-phase.
