Never touch the workpiece during or after welding - risk of burns.
Slag can jump off cooling workpieces. The specified protective equipment must therefore
also be worn when reworking workpieces, and steps must be taken to ensure that other
people are also adequately protected.
Welding torches and other parts with a high operating temperature must be allowed to cool
down before handling.
Special provisions apply in areas at risk of fire or explosion - observe relevant
national and international regulations.
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.
- 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).
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.
Factors affecting
welding results
The following requirements with regard to shielding gas quality must be met if the welding
system is to operate in a correct and safe manner:
- Size of solid matter particles < 40 μm
- Pressure dew point < -20 °C
- Max. oil content < 25 mg/m³
Filters must be used if necessary.
NOTE! There is an increased risk of soiling if ring mains are being used
Danger from
shielding gas cyl-
inders
Shielding gas cylinders contain gas under pressure and can explode if damaged. As the
shielding gas cylinders are part of the welding equipment, they must be handled with the
greatest of care.
