Final answer:
The oxyfuel welding station consists of an oxygen tank, fuel gas tank, welding torch, and regulators, with hoses and safety devices ensuring safe operation.
Step-by-step explanation:
The four main parts of an oxyfuel gas welding station are the oxygen tank, the fuel gas tank (commonly acetylene), the welding torch, and the regulators for each tank. The welding torch is used to mix the gases and control the flame, while the regulators are crucial for controlling the pressure and flow rate of the gases from their respective tanks to ensure a stable and appropriate flame for welding. Appropriate hoses and safety devices, such as check valves and flash arrestors, are also part of the station setup to provide safe operation.
