Requirement For The Shielding Gas; Danger From Shielding Gas Cylinders - Fronius Artis 170 Operating Instructions Manual

Slag may fly off cooling workpieces. Therefore, also wear regulation-compliant
protective equipment when reworking workpieces and ensure that other persons
are sufficiently protected.
Leave the welding torch and other parts with a high operating temperature to
cool before working on them.
Special regulations apply in areas at risk of fire or explosion
– follow the appropriate national and international regulations.
Welding systems for work in areas with increased electrical hazard (e.g., boilers)
must be labeled with the symbol (Safety). However, the welding system may not
be located in such areas.
Risk of scalding due to leaking coolant. Switch off the cooling unit before discon-
necting connections for the coolant supply or return.
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.
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.
