Gas supply pressures not within the specifications in the Specifications section can cause poor cut
quality, poor consumable life, and operational problems.
If the purity level of the gas is too low, or if there are leaks in the supply hoses or connections:
 Cut speeds can decrease.
 Cut quality can deteriorate.
 Cutting thickness capability can decrease.
 Consumables life can be shortened.
