Requirement For The Shielding Gas; Danger From Shielding Gas Cylinders; Safety Measures At The Installation Location And During Transport - Fronius KD 7000 D-11 Operating Instructions Manual

Odourless and colourless shielding gas may escape unnoticed if an adapter is used for the
shielding gas connection. Prior to assembly, seal the device-side thread of the adapter for
the shielding gas connection using suitable Teflon tape.
Requirement for Especially with ring lines, contaminated shielding gas can cause damage to equipment and
the shielding gas
reduce welding quality.
Meet the following requirements regarding shielding gas quality:
-
-
-
Use filters if necessary.
Danger from
Shielding gas cylinders contain gas under pressure and can explode if damaged. As the
shielding gas cyl-
shielding gas cylinders are part of the welding equipment, they must be handled with the
inders greatest of care.
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.
Safety measures A device toppling over could easily kill someone. Place the device on a solid, level surface
at the installation such that it remains stable
location and dur- -
ing transport
Special regulations apply in rooms at risk of fire or explosion
-
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.
