corrosion or changes caused by other environmental factors).
The testing interval and scope of testing must comply with applicable national
standards and directives as a minimum.
Danger from
shielding gas cyl-
inders
Shielding gas cylinders contain gas under pressure and can explode if damaged.
As the shielding gas cylinders are part of the welding equipment, they must be
handled with the greatest of care.
Protect shielding gas cylinders containing compressed gas from excessive heat,
mechanical 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 cylinders 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 international regulations for shielding gas cylinders and accessories.
Safety measures
at the installa-
tion location and
during 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 accident prevention regulations. This applies especially to guidelines regard-
ing the risks arising during transport.
After transporting the device, the device must be visually inspected for damage
before commissioning. Any damage must be repaired by trained service techni-
cians before commissioning the device.
