Protect shielding gas cylinders containing compressed gas from excessive heat, mechan
-
ical impact, slag, naked flames, sparks and arcs.
Mount the shielding gas cylinders vertically and secure according to instructions to prevent
them falling over.
Keep the shielding gas cylinders well away from any welding or other electrical circuits.
Never hang a welding torch on a shielding gas cylinder.
Never touch a shielding gas cylinder with an electrode.
Risk of explosion - never attempt to weld a pressurised shielding gas cylinder.
Only use shielding gas cylinders suitable for the application in hand, along with the correct
and appropriate accessories (regulator, hoses and fittings). Only use shielding gas cylin
-
ders and accessories that are in good condition.
Turn your face to one side when opening the valve of a shielding gas cylinder.
Close the shielding gas cylinder valve if no welding is taking place.
If the shielding gas cylinder is not connected, leave the valve cap in place on the cylinder.
The manufacturer's instructions must be observed as well as applicable national and inter
-
national regulations for shielding gas cylinders and accessories.
Danger from es

caping shielding
gas
Risk of suffocation from the uncontrolled escape of shielding gas
Shielding gas is colourless and odourless and, in the event of a leak, can displace the ox
-
ygen in the ambient air.
-
Ensure an adequate supply of fresh air with a ventilation rate of at least 20 m³/hour.
-
Observe safety and maintenance instructions on the shielding gas cylinder or the main
gas supply.
-
Close the shielding gas cylinder valve or main gas supply if no welding is taking place.
-
Check the shielding gas cylinder or main gas supply for uncontrolled gas leakage be

fore every start-up.
Safety measures
at the installation
location and dur
-
ing transport
A device toppling over could easily kill someone. Place the device on a solid, level surface
such that it remains stable
-
The maximum permissible tilt angle is 10°.
Special regulations apply in rooms at risk of fire or explosion
-
Observe relevant national and international regulations.
Use internal directives and checks to ensure that the workplace environment is always
clean and clearly laid out.
Only set up and operate the device in accordance with the degree of protection shown on
the rating plate.
When setting up the device, ensure there is an all-round clearance of 0.5 m (1 ft. 7.69 in.)
to ensure that cooling air can flow in and out freely.
When transporting the device, observe the relevant national and local guidelines and ac
-
cident prevention regulations. This applies especially to guidelines regarding the risks aris
-
ing during transport.
Do not lift or transport operational devices. Switch off devices before transport or lifting.
