Requirement For The Shielding Gas; Danger From Shielding Gas Cylinders - Fronius TWIN Push Operating Instructions Manual

When handling coolant, observe the information on the coolant safety data
sheet. The coolant safety data sheet can be obtained from your service center or
via the manufacturer's website.
Only use suitable load-carrying equipment from the manufacturer to transport
devices by crane.

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 exclus-
ively 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 mechanic-
al damage, corrosion, or changes due to other environmental influences).
The test interval and scope must at least comply with the respective valid nation-
al 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 in-
stallation.
Requirement for Especially with ring lines, contaminated shielding gas can cause damage to
the shielding gas equipment and reduce welding quality.
Meet the following requirements regarding shielding gas quality:
-
-
-
Use filters if necessary.
Danger from Shielding gas cylinders contain compressed gas and may explode if damaged.
Shielding Gas
Shielding gas cylinders are an integral part of the welding equipment, so they
Cylinders must be handled very carefully.
Protect shielding gas cylinders with compressed gas from excessive heat, mech-
anical 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.
Attach chains or ropes to all designated attachments of the suitable load-
carrying equipment.
Chains or ropes must be the smallest angle possible from vertical.
Remove gas cylinder and wirefeeder (MIG/MAG and TIG devices).
