System description
General
The MAXPRO200 plasma system is designed to cut a wide range of thicknesses of mild steel, stainless steel, and
aluminum.
Power supply
The power supply is a 200 A, 165 VDC constant-current supply. It contains the circuitry to ignite a torch, plus a heat
exchanger and a pump to cool the chopper and torch. The power supply has a discrete machine interface to provide
communication with a CNC.
Ignition console
The ignition console is attached to the outside of the rear panel of the power supply enclosure. The ignition console uses
a spark-gap assembly. The ignition console converts 120 VAC control voltage from the power supply into high-frequency
and high-voltage pulses (9–10 kV) to initiate the pilot arc at the torch electrode-nozzle gap. The high-voltage,
high-frequency signal is coupled to the pilot arc lead.
Torch
• The maximum production cutting capacity is the maximum thickness that can be cut with a 100% duty
cycle. The maximum production cutting capacity of the MAXPRO200 torch is 32 mm (1-1/4 inches)
for mild steel using the 200 amp O
2
/Air process, 22 mm (7/8 inch) for stainless steel, and 19 mm (5/8
inch) for aluminum using the 200 amp Air/Air process.
• Maximum pierce capacity is 32 mm (1.25 inches) for mild steel, 25 mm (1 inch) for stainless steel, and
32 mm (1.25 inch) for aluminum.
• The maximum severance capacity is the maximum thickness that can be severed without regard for
speed and cut quality. This thickness should only be cut occasionally and cannot be cut with a 100%
duty cycle. The maximum severance capacity of the MAXPRO200 torch is 75 mm (3 inches) for mild
steel, 63 mm (2-1/2 inches) for stainless steel, and 75 mm (3 inches) for aluminum.
Gas system
The gas system manages the pressure and timing of the gas supplied to the torch. It consists of a regulator, proportional
valves, pressure transducers, and an inline valve located in the torch lead.
