Disposal

Power tools, accessories and packaging should be sorted for environmental-

friendly recycling. Only for EC countries: Do not dispose of power tools into

household waste! According to the European Directive 2002/96 on waste

electrical and electronic equipment and its incorporation into national law,

power tools that are no longer suitable for use must be separately collected

and sent for recovery in an environmental-friendly manner.

1.0 Introduction

This document describes the assembly and operation of the SEAMTEK 36 manufactured by

Leister Technologies AG of Kägiswil, Switzerland. This includes setup and installation, operating

procedures, and a description and purpose of each of the various modules available for use

with your SEAMTEK 36. A troubleshooting checklist, warranty information, and an index are

also included in this documentation. This manual is designed to ensure proper setup,

installation, and operation of the SEAMTEK 36 with a minimum of effort. Please read through

all sections of this document before using your SEAMTEK 36.

This version supersedes any previously dated version and is superseded by any later dated

version.

Leister Technologies AG believes the information in this manual to be complete and accurate,

but makes no warranty, either actual or implied, as to the completeness and accuracy of this

information, and assumes no liability for the use of this information.

readability, these formatting styles are designed so that you will readily know references to a

particular button, for instance, from a discussion of that button's features.

These conventions are as follows:

All labels are written as they appear on the machine.

Note: Notes like this one are used to provide supplemental information.

The following symbols and notations provide additional cautionary information:

Warning: These messages warn against possible dangers that may occur as the result of unsafe

operating practices.

Warning:

Symbols, like this one, alert you to practices that may cause damage to the machine.

Opening the device is extremely dangerous, since live parts and

connections are exposed. Remove the plug from the socket before

opening the device.

Danger of fire and explosion if the extrusion welder is used

incorrectly (e.g. overheating of material), particularly near

combustible materials and explosive gases.

Danger –can cause burns ! Do not touch bare metal parts and

emerging material while hot. Allow the device to cool. Do not direct

stream of hot air or emerging material towards people or animals.

Connect device to power socket with protective earth conductor.

Any break in the protective earth conductor inside or outside the

device is dangerous!

Only use extension cables with a protective earth conductor!

Caution:

The nominal voltage indicated on the device must correspond to the

mains voltage. If power failure occurs, the main switch and drive

must be switched off (release locking device).

When using the device on building sites, a residual current circuit

breaker is essential for the safety of persons there.

The device must not be left unattended when in use. Heat can reach

combustible materials which are out of sight.

The device may only be used by trained personnel or under their

supervision. Children may not use the device under any

circumstances.

Keep away from wet and damp areas.

While working on the open system avoid wearing garments such as

shawls, scarves and ties. Long hair must be tied or protected by

headgear.

1.3 The SEAMTEK 36

Thank you for purchasing the world's finest rotary hot air welder. The SEAMTEK 36 is a

computer-controlled hot air welder used for sealing industrial coated fabrics such as

polyvinylchloride (PVC), polyurethane (PU), polyethylene (PE), and polypropylene (PP), which are

used today for a vast array of important and interesting products. These include tents, awnings,

tarpaulins, inflatable boats, water toys, geo-membranes, truck covers, farm building covers,

fishing waders, environmental and protective garments, lighter than air craft, and many other

applications. The possibilities are virtually limitless.

Figure 1 Front View of the SEAMTEK 36

Rotary hot air welding is a controlled and constant flowing process with speeds ranging from

.8 –72 feet per minute (0.25 –22 meters per minute), accommodating long fast seams or

slow intricate seams. Unlike dialectic welders which have been in use now for about 40

years, the SEAMTEK 36 can produce a wide variety of three-dimensional products. The

SEAMTEK 36 is fully shielded from RF radiation and works well as a compliment to RF

welding.

1.4 Operating Principle

In operation, the SEAMTEK 36 directs a stream of hot air (from 200 to 1300 ° F, 35°C - 700°C)

onto the joining surfaces of the coated fabric pattern pieces, which then roll between two drive

wheels where pressure is applied and the seam is welded.

1.5 SP Specifications

Utility Requirements

Air: 100-120 psi @1 cfm

Power: 230V~ to 240 V~, 50/60 Hz, single phase, 17 amps

Weight: 330k

The SEAMTEK 36 is a very precise machine in that it can maintain an air stream weld

temperature within +/-2 degrees F (°C) and can maintain the speed of each drive wheel

independently within +/- .01 inch per second at weld speeds ranging from 0.8 to 72’/min (0.25

–22 meters per minute). This precision insures high quality welds over a very broad range of

fabric types, welding speeds, and temperatures. The SEAMTEK 36 is a highly versatile machine

and works well in conjunction with other welding formats such as Radio Frequency (RF).

1.6 Technical Support

This manual is designed to serve as a complete, easy-to-use reference source for the SEAMTEK

36. If any questions concerning the use and/or maintenance of your SEAMTEK 36 cannot be

answered by this documentation, please contact Leister Technologies AG for further support.

2.0 Machine Physical Components

This section describes the various modules available for use with your SEAMTEK 36. Contact

Leister Technologies AG for further information on ordering optional modules.

The SEAMTEK 36 is a modular system. This allows several components to be field replaced in

minutes with no special tools required. It also allows the machine to be configured in several

different ways.

2.1 Base Frame

The base frame in constructed of steel, making it extremely strong stable platform.

2.2 Primary Power Panel

The Primary Power Panel is a metal NEMA box that is mounted to the vertical post of the

machine. This module houses the primary power management system and control computer
