Page 5: Overview Of Important Safety Instructions
2. Overview of Important Safety Instructions 2.1 Important Safety Instructions Warning Danger to life, high voltage! Before opening the device, pull the mains plug out of the socket, because volt- age-bearing components and connections will be exposed when it is opened! Danger of fire caused by improper use of the welding machine (e.g., material overheating) and particularly in the vicinity of combustible materials! Risk of burning! -
Page 6: Intended Use
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. -

Pay particular attention to the safety distance. A distance of 200 mm must be maintained, as the hot air nozzle unit swings out- ward. Warm air is blown out of the back of the machine. The distance to the wall must therefore be observed. SEAMTEK 900 AT SEAMTEK 2000 AT Required space for the machine 2380 × 1530 3530 ×... -
Page 9: Securely Positioning The Machine
The machine must only be operated at an altitude of up to max. 2,000 m above sea level. We cannot guarantee that the machi- ne will function properly if it is used at a higher altitude. Furthermore, ensure that the machine is only operated in conditions with a maximum humidity of 95% and a maximum tempe- rature of 45 °C. -

Page 13: Quickarm
The machine can be equipped with the quickarm (28) in two different ways. The quickarm (28) is either fitted to the machine directly by Leister or mounted on the machine afterwards by the customer. 6.4.3 Tape Delivery System The tape delivery system (29) is suitable for supplying tape during the joining process. -
Page 14: Welding Nozzle Position And Heat Input
Now set the welding nozzle (12) to the welding position under the “welding conditions” tab (set everything to “Automatic” mode). Each time an arm, the transport rollers (9), or welding nozzle (12) are changed, the position of the nozzle must be sub- sequently readjusted. -
Page 15: Changing The Welding Nozzle
7.1.3 Changing the Welding Nozzle Caution: Completely cool the machine with the cool-down mode before changing the welding nozzle (12). The welding nozzle (12) may still be hot even following the cool-down mode. A 25 mm welding nozzle (12) is mounted as standard. Nozzles are available in widths from 8 – 64 mm. Before mounting a new welding nozzle (12), use adjusting screw (Y) to turn the welding nozzle (12) as far as possible away from the machine in direction (-Y). -
Page 16: Air Outlet
7.1.6 Air Outlet Air from the pump that is not required in the machine is discharged from the machine via a bypass. This is why hot air can escape from the back of the machine. (Refer to the figure for residual air outlet) In addition, warm air can be blown out of the machine from the cooling air outlet (see figure), which is required to cool the pneumatic cabinet. -
Page 17: Emergency Stop Switch
7.4 Emergency Stop Switch The following occurs as soon as you press this switch: 1. The machine is disconnected from the power supply. The heating element and the pump are switched off. Caution: If the emergency stop switch is activated while the heating element is switched on, this can cause considerable damage to the machine. -

Make sure that the correct arm is selected to prevent damage to the drive. Danger of crushing! When the nozzle is retracted, there is a risk of crushing because of pneumatically mo- ving parts. -
Page 20: Quickarm
7.10.3 Quickarm Activating the Quickarm Make sure that the upper transport roller (9) is open. (See point 7.8.1) Pull the upper retaining pin (28 A) out, to disengage the locking mechanism for the quickarm (28). Now carefully fold the arm downward and fit the lower retaining pin (28 B) until it fully engages. -
Page 21: Transport Rollers
7.11 Transport Rollers 25 mm wide transport rollers (9) are mounted as standard. The powered transport rollers (9) clamp and transport the material. The maximum roller speed for original Leister accessory rollers is 30 m/min. 7.11.1 Changing the Transport Rollers Caution: Fully execute the cool-down mode so that any operating personnel that unintentionally come into contact with hot components when changing the rollers do not suffer burns. -
Page 22: Guide Holder
Risk of Crushing Danger: Do not reach between moving components, e.g., the transport rollers (9). When working on the open system, do not wear articles of cloth- ing such as scarves, shawls, or neckties and tie up long hair or protect it by wearing headgear. -
Page 23: Mounting And Adjusting The Guide
7.12.1 Mounting and Adjusting the Guide Caution: First adjust the welding nozzle (12) according to Chapter 7.1.1 before the guide is mounted. To fasten a guide, check whether the welding nozzle (12) has been adjusted. Insert the rod and then clamp the guide holder (11) with the clamping lever. -
