Gas requirements
The customer must furnish all gases and gas-supply regulators for the system. Use high-quality, 2-stage pressure
regulators located within 3 m (10 ft) of the power supply or optional fuel-gas console. See Gas regulators in this section
for recommendations. See Section 2 for gas and flow specifications.
Caution: Gas supply pressures not within the specifications in Section 2 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
• Parts life can shorten
Setting the supply regulators
1. Make sure the power is OFF. Set the oxygen regulator pressure to 8.3 bar (120 psi). Set the air regulator pressure to
7.2 bar (95 psi). If an optional fuel-gas console is being used, set H35, F5, and N
2
pressures to 8.3 bar (120 psi).
2. Turn ON the power.
3. After the purge cycle stops, move the selection switch to the SET position.
4. Adjust all regulators while gas is flowing. Return to the supply regulators and adjust them to match the values in
step 1.
5. Move the selection switch back to the RUN position (center).
