TheCommand THC workswith X-Y or robotic plasmacutting systems to controlthis crucial parameter andmaximize plasma cuttingquality and productivity.PERCENT OF CONSUMABLE LIFE(EITHER STARTS OR ARC HOURS)100%50%STAND-OFFVOLTSConsumable Life DeviationWork Piece SurfaceNominalHyperthermCompetitionx2 Nominal-8V -5 -1 0 -15 +8VTORCH HEIGHT ERRORCommand THC maximizes consumable life.PERCENT CHANGE FROMNOMINAL KERF WIDTH30%30%STAND-OFFVOLTS0%Kerf Width VariationWork Piece SurfaceNominalHyperthermCompetitionx2 Nominal-8V -5 -1 0 -15 +8VTORCH HEIGHT ERRORCommand THC maximizes the ability to maintaina constant kerf width because of the precise torchheight control.The SystemThe Command THC is a microprocessorbasedtorch height control system designedto accurately set the initial piercing heightand control the torch-to-work distanceof a plasma torch during cutting operation.The system includes a Command THCcontrol module, plasma system interfacemodule, a torch lifter assembly, severalinterconnecting cables and an optionaloperator control pendant.Superior Height Control■ Z-axis correction speed is variable anddepends on the amount of voltage error.■ The system will respond to arc voltagechanges of less than 1 volt.■ Maximum speed of retract exceeds200 ipm (5.0 m/min).■ Built-in Ohmic touch-retract initialheight sensing (IHS) feature ensuresaccurate, repeatable initial piercingheight settings.■ A work-clear feature senses the loss ofOhmic contact for accurate positioning,even on thin, flexible sheet metal.■ Built-in motor-stall IHS feature is alwaysactive and serves as a back-up forthe Ohmic IHS. This feature is the IHSmeans for non-conductive workpiecesurfaces, such as painted plate.■ Rapid pull-back feature moves the torchaway from the workpiece if a touch isdetected during cutting. (patents pendingworldwide). This collision avoidancefeature will prevent many unforeseentorch crashes such as workpieces thattip up or buckle.
