• Install and secure cylinders in an upright position by chaining them to stationary support or equipment cylinder rack to prevent falling or tipping. • Never allow a welding electrode to touch any cylinder. • Turn face away from valve outlet when opening cylinder valve. • Keep protective cap in place over valve except when cylinder is in use or connected for use. • Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1. ! DANGER Never use flammable gasses with MIG welders. Only inert or nonflammable gasses are suitable for MIG welding. Examples are carbon dioxide, argon, helium, or mixtures of one or more of these gasses. Never lift cylinders ! WARNING off the ground by their valves, caps, or with chains or slings. POLARITY For gas shielded welding, plug the cable coming out of the torch into the (+) socket and the ground clamp cable into the (-) socket on the welder. GAS TYPES There are 3 types of gas generally used for gas metal arc welding; 100% argon, a mixture of 75% argon and 25% carbon dioxide (C25) or 100% carbon dioxide. All can be used, but the 75/25 mixture is recommended for general welding. For aluminum welding, use 100% Argon. Either type gas may be obtained at your local welding supply outlet. Secure cylinder in place on your welding machine or other support to prevent the cylinder from falling over. REGULATOR This regulator is designed to be used with straight Argon or Argon mix gas. A threaded adapter is needed if CO2 is used. An adapter is available at your local welding gas supplier to change between the two. HOOKUP PROCEDURE Cylinder gas is ! WARNING under high pressure. Point cylinder outlet away from yourself and any bystanders before opening. 1. With the cylinder securely installed, remove the cylinder cap, stand to the side of the cylinder opposite the outlet, and open the valve slightly, turning counterclockwise. When gas is emitted from the cylinder, close the valve by turning clockwise. This will blow out dust or dirt that may have accumulated around the valve seat. 2. Install the gas regulator onto the gas cylinder and tighten the stem nut securely to the gas valve. 3. Install one end of the gas hose to the fitting on the rear of the welder and the other end to the fitting on the regulator using hose clamps on each connection. Make sure the gas hose is not kinked or twisted. 4. Once again, stand opposite the cylinder outlet and slowly open the cylinder valve. Inspect for leaks in the connections. 5. This regulator is factory preset at 30cfh. No adjustment is necessary. Also, a pop-out indicator in the end of the regulator shows the amount of gas left in the cylinder. When not extended, the cylinder is approximately 10 minutes away from empty. 6. Remember to close the gas valve when finished welding.
