WARNING

BUILDUP OF SHIELDING GAS may harm health or kill.

Shut off shielding gas supply

when not in use.

SEE AMERICAN NATIONAL STANDARD Z-49.1, SAFETY IN WELDING AND CUTTINGPUB- LISHED BY THE AMERICAN WELDING SOCIETY.

1.Chain the cylinder to a wall or other stationary sup- port to prevent the cylinder from falling over. Insulate the cylinder from the work circuit and earth ground.

3.Attach the flow regulator to the cylinder valve and tighten the union nut securely with a wrench. The flow regulator for carbon dioxide must have a plas- tic washer seated in the fitting that attaches to the cylinder to prevent leakage. Refer to K1800-1 in the accessories section.

4.Refer to Figure A.6. Attach one end of inlet gas hose to the outlet fitting of the flow regulator and tighten the union nut securely with a wrench. Connect the other end to the SP-135 PLUS Gas Solenoid Inlet Fitting (5/8-18 female threads for CGA 032 fitting). Make certain the gas hose is not kinked or twisted.

INPUT CONNECTIONS

Refer to Figure A.6.

The SP-135 PLUS has two input connections, the power input cable, and the Gas Solenoid Inlet Fitting. Both are located on the rear of the machine.

2. With the cylinder securely installed, remove the

 

cylinder cap. Stand to one side away from the out-

Power

let and open the cylinder valve very slightly for an

Input

instant. This blows away any dust or dirt which may

Cable

have accumulated in the valve outlet.

 

WARNING

BE SURE TO KEEP YOUR FACE AWAY FROM THE VALVE OUTLET WHEN CRACKINGTHE VALVE. Never stand directly in front of or behind the flow regulator when opening the cylinder valve. Always stand to one side.
