CHECK VALVES•Are installed to prevent the reverse flow of gases that would result in a combustible mixture in the welding hose, check valves are mounted to the welding torch handle and at the regulator outlet connection.

•Check valves are necessary safety devices attached between the hoses and the regulator outlets.

TORCH HANDLE

• The torch handle is probably the most frequently used item in a welding shop.

• Cutting attachments, welding tips and heating nozzles are all connected to the torch handle.

• Always inspect the torch handle head, valves and hose connections for oil, grease or damaged parts.

• Oxygen connection is usually marked “OXY”

• Acetylene connection is usually marked “FUEL”

WELDING NOZZLE

•Inspect the cone end, coupling nut, o-rings and welding nozzle for damage, oil or grease.

•Connect the welding nozzle to the torch handle. Tighten the coupling nut hand-tight only. Wrench tightening may damage o-rings and create a faulty seal allowing leaks.

•Note- There must always be two o-rings on the cone end of the nozzle. The absence or damage of either of these o-rings allows premixing and leaks of oxygen and acetylene.
