Gas regulators
Low-quality gas regulators do not provide consistent supply pressures and can result in poor cut quality and system 
operation problems. Use a high-quality, 1-stage, gas regulator to maintain consistent gas supply pressure, if using liquid 
cryogenic or bulk storage. Use a high-quality, 2-stage, gas regulator to maintain consistent gas supply pressure from 
high pressure gas cylinders.
The high-quality gas regulators listed below are available from Hypertherm and meet U.S. Compressed Gas Association 
(CGA) specifications. In other countries, select gas regulators that conform to national and local codes.
