Leister SEAMTEK W-AT
Welding machine
Read through the operating instructions before commissioning
for the first time. Always store these operating instructions with the device.
Do not pass the device on to anyone else without the operating instructions.
Thank you for purchasing this first-class hot-wedge welding machine from Leister. The SEAMTEK W-AT is a comput-
er-controlled hot-wedge welding machine that is used for joining laminated industrial textiles, e.g., polyvinyl chloride
(PVC), polyurethane (PU), polyethylene (PE), and polypropylene (PP). Today, these industrial textiles are used for a mul-
titude of important and interesting products, including 3D applications, tents, tarpaulins, inflatable objects, geomem-
branes, truck tarpaulins, coverings for the agricultural sector, fishing equipment, protective clothing, protective covers,
pipes, synthetic leather, and many more. The possibilities are practically unlimited.
The SEAMTEK W-AT is manufactured by Leister Technologies AG in Kägiswil, Switzerland. These operating instructions
provide detailed explanations of the following:
• Setting up and installing the SEAMTEK W-AT
• All operating sequences
• Description and tasks of the various modules that are available when using your SEAMTEK W-AT
These operating instructions also include a list of troubleshooting tips, warranty information, and a clearly structured
table of contents. Please read through all of the sections in these operating instructions carefully before using your
SEAMTEK W-AT for the first time.
These operating instructions supersede all operating instructions with an earlier date. The older versions no longer ap-
ply. When a new version of the operating instructions is issued, this version will be superseded and will no longer apply.
Leister Technologies AG makes every eort to ensure that the information contained in this manual is complete and
exact. No guarantee, either concrete or implied, is however provided, nor is any liability assumed for the use of this
information with respect to either its completeness or accuracy.
This manual may be updated from time to time without prior notice. The latest version of all operating instructions
published by Leister Technologies AG can be obtained by authorized users upon request to Leister Technologies AG.
1. SEAMTEK W-AT
Congratulations on purchasing your SEAMTEK W-AT.
You have chosen a first-class hot-wedge welding machine.
It was developed and produced in accordance with the latest advances in the plastics-processing industry. It has also
been manufactured using high-quality materials.
1.1 Using this Manual
Two versions of the SEAMTEK W-AT are available. The SEAMTEK W-900AT with 900mm working area and the W-2000AT with
2000mm working area. Unless otherwise noted, all function descriptions, instructions, warnings, cautions and symbols apply for
both versions. The illustrations are based on the SEAMTEK W-900AT, the dimensions may dier for the W-2000AT. In the follow-
ing, the abbreviation SEAMTEK W-AT refers to both versions.

2. Overview of Important Safety Instructions
Warning
Danger to life due to high voltage
Before opening the switch cabinet, the device must be disconnected from the power supply at all poles.
(Disconnect the power plug.) Live components and connections may be exposed in the process.
Risk of fire
There is a risk of fire if the welding machine is used improperly (e.g., due to the material overheating),
particularly in the vicinity of flammable materials.
Risk of burning!
Do not touch the hot-wedge holder, hot wedge, and stepping motors when they are hot. Do not wear any
jewelry or watches, particularly on the hands, arms, and fingers. The device should always be allowed
to cool down first.
Connect the device to an outlet with a protective conductor.
Any interruption of the protective conductor inside or outside of the device is dangerous.
Only use extension cables with protective conductors.
Risk of poisoning
Gases are released during the processing of plastics, lacquers, or similar materials that could be aggres-
sive or toxic. Avoid breathing in vapors, even if they seem to be harmless. Make sure the workplace is
well-ventilated at all times or wear a breathing mask.
Risk of crushing
There is a risk of crushing due to the movement of mechanical and/or electromechanical parts. Take the
necessary precautions to prevent hazards posed by mechanical parts.
Risk of entanglement
Avoid reaching between moving parts such as the transport rollers in order to prevent objects or body
parts becoming entangled.
Two people are needed to move the machine. Make sure that the machine cannot topple over.
Caution
The nominal voltage specified on the device must match the local line voltage. If the supply voltage
fails, the main switch and the drive must be switched o.
RCD When using the device, a residual-current circuit breaker is required to protect the personnel working
at the site where the device is being used.
The device must be supervised at all times during operation. Waste heat can come into contact with
flammable materials that are not in view.
Device may be operated only by trained specialists or under their supervision. Children are not permit-
ted to operate the device under any circumstances.
Protect the device from moisture and wet conditions.
When working on the open system, do not wear such articles of clothing as scarves, shawls, or neck-
ties. Tie up long hair or protect it by wearing headgear.
Wear protective goggles
In certain processes, various metal parts and materials are heated to high temperatures and can produce
splashes if handled incorrectly. Operating sta and persons in the immediate vicinity of the device must
therefore wear protective goggles.
