Intended Use; Improper Use; Welding Vapors; Extraction - Leister SEAMTEK W-AT Series Manual

2.2 Intended Use

The SEAMTEK W-AT has been designed for the professional welding of thermoplastics.
Use only original Leister spare parts and accessories; otherwise, any warranty or guarantee claims will be invalidated.

2.3 Improper Use

Any other use or any use beyond the type of use described is deemed non-intended use.

2.4 Welding Vapors

Danger: Welding certain materials can result in the formation of poisonous vapors. You must there-
fore ensure that enclosed rooms are well-ventilated at all times. If this is not possible, the welding
vapors must be extracted. Always pay attention to the safety data sheet for the material being pro-
cessed.
Make sure to use the correct welding parameters. When redetermining the welding parameters, start with a low energy
value and increase it until you achieve a good weld result. This will ensure that the weld materials are not burned and
will reduce welding vapors. As an accessory, Leister offers an adapter for the SEAMTEK W-AT, which can easily be
mounted on an external vacuum device. Please ask your distribution partner about this.
2.4.1

Extraction

The vacuum device (Leister accessory 155.410) is supplied without an extraction unit. Therefore, Leister recommends
the following unit properties.
Volume flow
Hose connection
The extracted air can be filtered with an internal filter unit. The unit used must be equipped with a multi-stage filter com-
bination to filter gases and smoke.
If the extracted air is not filtered internally, the exhaust gases can also be conducted out of the building. We recommend
the Leister Airpack (119.358) as an external blow-off unit. Local laws and regulations must be observed for this purpose.

2.5 Operating Modes

• Normal operation: In this mode, the machine welds material. The machine can be used in manual (axes on/
off manually), automatic (axes controlled automatically), and semi-automatic operation (mixture of manual and
automatic).
• Setup operation: Everything must be set up first in order to prepare the machine for normal operation. This is
done in the setup operation mode. Some elements of setup operation are performed manually or semi-automati-
cally.
• Maintenance/service/repairs/installation: In this mode, the machine is not in operation. The machine must be
disconnected from all types of energy supply before performing the relevant tasks.

2.6 Specialists and Training

• Operators: The personnel responsible for setting up, operating, and cleaning the machine are defined as opera-
tors.
These personnel are obliged to carefully read the operating instructions and to observe the safety instructions
contained therein. In addition, the operators are instructed by the administrators on how to operate the machine.
• Administrator: The personnel responsible for the repair, maintenance, installation, and adjustment of the ma-
chine are defined as administrators. These personnel must be trained extensively by Leister Technologies AG or by
a representative instructed to do so.
These personnel are obliged to carefully read the operating instructions and to observe the safety instructions
contained therein.
• Specialists: Specialists are responsible for commissioning the machine correctly and must have received elec-
tronic or electrical training.
These personnel are obliged to carefully read the operating instructions and to observe the safety instructions
contained therein.
