Hand-held air plasma cutting system designed for heavy fabrication

Miller Electric Mfg. Co. has introduced the Spectrum® 1251 air cutting and gouging system, designed for hand-held and automated cutting in heavy fabrication, manufacturing, demolition, and maintenance applications.

The cutting system, suitable for steel up to 1.75 in., has a 100-amp output and a 1.25-in. rated cutting capacity. The machine cuts -in. steel at 25 IPM, 5/8-in. steel at 40 IPM, and -in. steel at almost 140 IPM. It also cuts stainless steel, aluminum, copper, and any electricity-conducting metal.

The system, which also provides gouging capabilities, weighs 97 lbs. and includes Auto-Line™ power management technology. Maintaining a constant cutting arc, the technology enables direct connection to any 50- or 60-Hz, three-phase primary power level from 190 to 630 VAC, in addition to adjusting for spikes or losses in input voltage levels. Line voltage compensation (LVC™) provides peak power under variable input voltage conditions for steady, clean end cuts.

Auto-Refire™ technology automatically controls the pilot arc when cutting expanded metal or multiple pieces of metal. It switches the pilot arc to initiate the cutting arc on or off as fast as necessary, automatically providing maximum power for cutting thicker or hardened metals. It is designed to reduce operator hand fatigue and increase comfort.

A patented Ultra-Quick Connect™ torch allows simplified plasma torch connection and removal. The ICE-100T torch—in 25-ft. or 50-ft. cable options—includes a drag shield that attaches to the cup and holds the tip 1/8 in. off the workpiece, enabling the operator to drag the torch on the workpiece while cutting at full output. Torch automation packages come with cable assemblies for CNC/robotic interface.

Wind Tunnel Technology™ allows airborne contaminants to flow through a center channel instead of through the unit's internal components, helping to prevent abrasive dust and particle damage. The Fan-on-Demand™ cooling system, operating only when needed, reduces airborne contaminants pulled through the machine, helping to keep internal components cleaner and reduce maintenance.
