3-23 INSTALLATION/SETUP
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.

NOTE
The regulator/flow meters used with argon based and carbon dioxide shielding gases are different. The
regulator/flow meter supplied is for argon based shielding gases. If carbon dioxide is to be used a suitable
carbon dioxide regulator/flow meter will need to be fitted.
NOTE
All valves downstream of the regulator must be opened to obtain a true flow rate reading on the outlet
gauge. (Welding power source must be triggered) Close the valves after the pressure has been set.
