Shielding Gas Regulator Safety
This regulator 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 are listed below.
1. NEVER subject the regulator to inlet pressure greater than its rated inlet pressure.
2. NEVER pressurize a regulator 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 until the gas pressure has been relieved. Under
pressure, gas can dangerously propel a loose part.
3. Do NOT remove the regulator from a cylinder without first closing the cylinder valve and releasing gas in the
regulator high and low pressure chambers.
4. Do NOT use the regulator 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 to cylinder. NEVER CONNECT a regulator designed for a particular gas or gases to a
cylinder containing any other gas.
