Requirement For The Shielding Gas; Danger From Shielding Gas Cylinders - Fronius TransPocket 4000 CEL Bedienungsanleitung

Power sources for work in areas with increased electric risk (e.g. near boilers) must carry
the "Safety" sign. However, the power source must not be located in such areas.
Risk of scalding from escaping coolant. Switch off cooling unit before disconnecting cool-
ant flow or return lines.
Observe the information on the coolant safety data sheet when handling coolant. The cool-
ant safety data sheet may be obtained from your service centre or downloaded from the
manufacturer's website.
Use only suitable load-carrying equipment supplied by the manufacturer when transporting
devices by crane.

If the wire-feed unit is attached to a crane holder during welding, always use a suitable,
insulated wirefeeder hoisting attachment (MIG/MAG and TIG devices).
If the device has a carrying strap or handle, this is intended solely for carrying by hand. The
carrying strap is not to be used if transporting with a crane, counterbalanced lift truck or
other mechanical hoist.
All lifting accessories (straps, handles, chains, etc.) used in connection with the device or
its components must be tested regularly (e.g. for mechanical damage, corrosion or chang-
es caused by other environmental factors).
The testing interval and scope of testing must comply with applicable national standards
and directives as a minimum.
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.

Hook chains and/or ropes onto all suspension points provided on the load-carrying
equipment.
Chains and ropes must be at the smallest angle possible to the vertical.
Remove gas cylinder and wire-feed unit (MIG/MAG and TIG devices).
