Especially with ring lines, contaminated shielding gas can cause damage to equipment
and reduce welding quality.
Meet the following requirements regarding shielding gas quality:
- Solid particle size < 40 μm
- Pressure condensation point < -20 °C
- Max. oil content < 25 mg/m³
Use filters if necessary.
In the event of crane attachment of the wirefeeder during welding, always use a suitable, insulating
wirefeeder hoisting attachment (MIG/MAG and TIG devices).
If the device is equipped with a carrier belt or handle, then this is used exclusively for transport by
hand. The carrier belt is not suitable for transport by crane, counterbalanced lift truck or other
mechanical lifting tools.
All lifting equipment (belts, buckles, chains, etc.), which is used in association with the device or its
components, must be checked regularly (e.g. for mechanical damage, corrosion, or changes due to
other environmental influences).
The test interval and scope must at least comply with the respective valid national standards and
guidelines.
There is a risk of colorless, odorless shielding gas escaping without notice if an adapter is used for the
shielding gas connection. Use suitable Teflon tape to seal the thread of the shielding gas connection
adapter on the device side before installation.

Danger from
Shielding Gas
Cylinders
Shielding gas cylinders contain compressed gas and may explode if damaged. Shielding gas cylinders
are an integral part of the welding equipment, so they must be handled very carefully.
Protect shielding gas cylinders with compressed gas from excessive heat, mechanical impact, slag,
open flames, sparks, and arcs.
Mount the shielding gas cylinders vertically and secure them in accordance with instructions so they
cannot fall over.
Keep shielding gas cylinders away from 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 weld on a compressed shielding gas cylinder.
Always use suitable shielding gas cylinders for the application in question and the correct matching
accessories (controller, hoses, and fittings, etc.) Only use shielding gas cylinders and accessories that
are in good condition.
If a valve on a shielding gas cylinder is open, turn your face away from the outlet.
When no welding is taking place, close the valve of the shielding gas cylinder.
Leave the cap on the valve of the shielding gas cylinder when the cylinder is not connected.
Follow the manufacturer’s instructions and applicable national and international provisions for
shielding gas cylinders and accessories.
