5.01 Shielding Gas Regulator/Flowmeter Operating Instructions
!
WARNING
This equipment is designed for use with welding grade (Inert) shielding gases only.
Shielding Gas Regulator/Flowmeter Safety
This regulator/flowmeter is designed to reduce and control high pressure gas from a cylinder or pipeline to
the working pressure required for the equipment using it.
If the equipment is improperly used, hazardous conditions are created that may cause accidents. It is the users
responsibility to prevent such conditions. Before handing or using the equipment, understand and comply at
all times with the safe practices prescribed in this instruction.
SPECIFIC PROCEDURES for the use of regulators/flowmeters are listed below.
1. NEVER subject the regulator/flowmeter to inlet pressure greater than its rated inlet pressure.
2. NEVER pressurize a regulator/flowmeter that has loose or damaged parts or is in a questionable
condition. NEVER loosen a connection or attempt to remove any part of a regulator/flowmeter until
the gas pressure has been relieved. Under pressure, gas can dangerously propel a loose part.
3. DO NOT remove the regulator/flowmeter from a cylinder without first closing the cylinder valve and
releasing gas in the regulator/flowmeter high and low pressure chambers.
4. DO NOT use the regulator/flowmeter as a control valve. When downstream equipment is not in use for
extended periods of time, shut off the gas at the cylinder valve and release the gas from the equipment.
5. OPEN the cylinder valve SLOWLY. Close after use.
User Responsibilities
This equipment will perform safely and reliable only when installed, operated and maintained, and repaired in
accordance with the instructions provided. Equipment must be checked periodically and repaired, replaced,
or reset as necessary for continued safe and reliable performance. Defective equipment should not be used.
Parts that are broken, missing, obviously worn, distorted, or contaminated should be replaced immediately.
The user of this equipment will generally have the sole responsibility for any malfunction, which results from
improper use, faulty maintenance, or by repair by anyone other than an accredited repairer.
!
CAUTION
Match regulator/flowmeter to cylinder. NEVER CONNECT a regulator/flowmeter designed for a particular gas or gases to
a cylinder containing any other gas.
