An oxygen cylinder is pressurized to __ pounds?

• A. Welding torch
• B. Striker
• C. 2,200
• D. 244

Answer: (C)

Oxygen cylinders are stored under very high internal pressure to hold enough gas for use. A full oxygen cylinder typically is pressurized to about 2,200 psi, which provides ample oxygen for welding tasks until the gas is drawn down by the regulator and torch. The other options aren’t appropriate: a welding torch and a striker are tools, not pressure values, and 244 psi is far too low to describe a full cylinder’s stored pressure. As you use gas, the cylinder pressure drops from roughly 2,200 psi down toward the regulator’s set working range.
