2.14 Shielding gas
NOTE! Handle shielding gas bottle with care. Assess the risks associated with handling and using
compressed gas. Always use a cylinder transport carriage and secure the cylinder safely.
There are many different suppliers of quality shielding gases for welding. Please ensure that
you are selecting the correct gas for your application. FastMig products use welding programs
for synergic and pulsed welding. These programs are created and recommend against a
particular shielding gas.
Shielding gas effects welding performance and is a fundamental component to overall weld
quality.

NOTE! Shielding gas flow rate from the welding gun is set according to the application, weld joint,
gas type and gas nozzle shape and size. The flow rate should be measured at the welding gun
nozzle before welding via a rotameter, and normally measure's between 10 – 20 litres per minute
for many welding applications.
2.14.1 Installing gas bottle
Always fasten the gas bottle properly in the vertical position, in a special holder against the
wall or on a cylinder carriage. Remember to close gas bottle valve after welding.
