1.With cylinder securely supported, stand on side of cylinder opposite cylinder outlet then remove cylinder cap and open valve slightly by turning counterclockwise. When gas is emitted from cylinder, close valve by turning clockwise. This will blow out dust or dirt that may have accumulated around valve seat.
2.Install regulator onto cylinder valve. Tighten stem nut securely to gas valve.
3.Install one end of gas hose to fitting on the back of welder and other end of hose to fitting on regulator. Make sure gas hose is not kinked or twisted.
4.While standing opposite cylinder outlet, slowly open cylinder valve. Inspect for leaks in the connections.
5.Remember to close gas cylinder valve when finished welding.
