Zusammenfassung:	PURPOSE: A valve assembly of a vaporizer for a welding apparatus is provided to prevent gas leakage through fine cracks are generated in a packing member by installing packing members in a seat valve in multistage. CONSTITUTION: A valve assembly(100A) of a vaporizer for a welding apparatus comprises a valve housing, a seat valve(110), a plurality of packing materials(130), and a plurality of sealing protrusions(105). Gas passes through the inlet(102) and the outlet(103) of the valve housing. The seat valve is installed in the hollow portion of the valve housing and moved by the pressure of the gas. The seat valve opens/closes the exhausting hole and is stepped more than at least two stages.
