Operation
3.6 Shielding gas regulator operating instructions
WARNING
This equipment is designed for use with welding grade (Inert) shielding gases only.
NOTE
Shielding Gas is not required if the unit is used with self shielded FCAW (flux cored arc
welding) wires
Shielding Gas Regulator Safety
Gas regulators are 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 the manufacturer's instructions.
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/ ow meters used with argon based and carbon dioxide shielding gases are
different. A suit able regulator/ ow meter will need to be fitted.
NOTE
All valves downstream of the regulator must be opened to obtain a true ow rate reading on
the outlet gauge. (Welding power source must be triggered) Close the valves after the pressure
has been set.
Installation
1. Remove cylinder valve plastic dust seal. Clean the cylinder valve outlet of impurities that
may clog orifices and damage seats before connecting the regulator. Crack the valve
(open then close) momentarily, pointing the outlet away from people and sources of ignition.
Wipe with a clean lint free cloth.
2. Match regulator to cylinder. Before connecting, check that the regulator label and cylinder
marking agree and that the regulator inlet and cylinder outlet match. NEVER CONNECT
a regulator designed for a particular gas or gases to a cylinder containing any other gas.
3. Connect the regulator inlet connection to cylinder or pipeline and Tighten it firmly but
not excessively, with a suitable spanner.
4. Attach supplied gas line between the regulator output and the desired input at the rear
of the power source.
Ensure that the gas
cylinder is secured to
a building pillar, wall
bracket or otherwise
securely fixed in an
upright position.
