Of all the plasma cutters in the industry, only the Spectrum 375 CutMateā„¢, Spectrum 2050 and Spectrum 3080 plasma cutters consistently cut steel at or greater than 3/8 in. when using generator power. In fact, the Spectrum 2050 offers 133 percent more cutting power than other units.

When powered by a welding engine drive with 12 kW of generator power, such as the PipePro 304, the Spectrum 2050 quality cuts steel up to 3/4 in. thick and stainless and aluminum up to 5/8 in. When connected to a generator with at least 8 kW of power, such as the Bobcat 225 NT, it cuts steel up to 5/8 in. The Spectrum 3080 cuts steel up to 7/8 in. thick and stainless and aluminum up to 3/4 in. when connected to 12 kW generator power. The Spectrum 375 CutMate cuts steel up to 3/8 in. thick and aluminum up to 1/4 in. when connected to a 6 kW generator.

Spectrum plasma cutters feature special circuitry that enables them to achieve full cutting power and maintain a steady cutting arc when connected to generator power," said Brian Schmidt, product manager, Miller Electric. "Other plasma cutters simply can't manage the voltage dips that inherently occur when using generator power. As a result, competitive 55 amps machines cannot cut metal thicker than 3/8 in. - that's a 133 percent loss of cutting power."

Schmidt also emphasized that machines without the Spectrum's circuitry are also prone to erratic arcs, inconsistent cutting performance and excessive circuit board failures.

The Spectrum 375 CutMate, Spectrum 2050 and Spectrum 3080 respectively deliver 27, 55 and 80 amps of cutting power and weigh just 49, 70 and 74 lb. Compared to cut-off wheels, saws or snips, they often complete jobs two to 10 times faster. The Spectrum 375 CutMate slices through 3/8 in. steel at 16 IPM, while the Spectrum 2050 and Spectrum 3080 slice through 1/4 in. steel at 70 IPM and 100 IPM, respectively.

Compared to an oxy-acetylene rig, which can only cut steel, plasma cutters offer more flexibility. They can cut any metal that can conduct electricity, making them the preferred cutting tool by mechanical contractors, independent owner-operators and other who often encounter stainless steel and aluminum on the job site.

Unmatched Flexibility

When considering a portable plasma cutter that will work at many different job sites, note that the Spectrum 2050 features Auto-Line. Auto-Line primary power management technology allows this unit to accept input voltages from 190 through 630 V, single- or three-phase, 50 or 60 Hz.

"You can plug the Spectrum 2050 into practically any outlet in the world," said Schmidt. "Even if the primary power spikes and dips, but stays within the 190 to 630 V range, the Auto-Line technology provides a steady, consistent arc and full cutting power."
