Item 63787 Installation Instructions Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product. 1. Wear ANSI-approved safety goggles. To clean the shielding gas cylinder’s valve, keep your face and ears away from the valve then open it slightly and immediately close it. This is called “cracking” the valve. It clears the valve of dust before connection. Note: Do not use thread seal tape or compound on the fittings on this Regulator. They will weaken any connection they are used on. 2. Connect the Regulator to the shielding gas cylinder’s valve and wrench tighten the connection. 3. Back the Knob on the Regulator off fully to prevent flow. 4. Connect the gas line from the outlet of the Regulator to your welding equipment. Wrench tighten all connections. Operation Instructions Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document including all text under subheadings therein before set up or use of this product. 1. Check that the gas line and welding system are completely set up and all connections are tight. 5. Open all gas valves that are downstream from the Regulator. 2. Check that the Regulator is securely fastened to the shielding gas cylinder and the Knob on the Regulator is backed off fully. 6. Slowly tighten the Knob on the Regulator while keeping an eye on the Flow Gauge until it indicates the desired SCFH flow rate. 3. Open the valve on the shielding gas cylinder slightly until the cylinder pressure gauge stops moving, then open it fully. 7. Close valve on welder until ready to start welding. 4. Close the gas valve on the welder. Check all pressurized connections for leaks using soapy water. Tighten or replace leaking connections as needed. Item 63787 8. After use, close cylinder valve fully and open all valves downstream from the Regulator to release all pressure on it. Back off the Knob on the Regulator until it is just loose and then tighten it back down 1 turn to prevent damage to the valve seat. For technical questions, please call 1-888-866-5797.
