*NOTE:Oxygen pressure: Set while cutting lever is depressed; pressure measured at the torch.
Natural gas or propane pressure: Set while cutting lever is depressed and fuel gas valve is wide
open; pressure measured at the torch.
OPERATING DATA
GENERAL NOTE:
1. 1/2" (12.7 mm) hose is recommended for oxygen, 3/8" (9.5 mm) hose is recommended for fuel gas.
2. Oxygen pressure is measured at the torch inlet connection.
3. The conditions listed in the table are based on typical conditions for cutting mild steel at ambient temperatures.
They should only be used as a starting point. Cut quality can vary depending on the temperature and metallurgical
content of the steel, steel quality, surface condition, oxygen purity, etc., in addition to the pressures and cutting
speed.
4. The post mix nozzles have divergent bore cutting orifices that are intended for applications where it is necessary
to cut quickly. For other specific applications, contact your ESAB representative or distributor.
