    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 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.

    These elements may still be warm even following the cool-down mode. The Seamtek 900 AT is a hot-air welding machine. Depending on the respective process, some components can become incredibly hot. Always operate the machine with due caution.

  • 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.

    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 suff er burns.

  • Page 22: Guide Holder

    The SEAMTEK 900 AT features two different pressure modes. Using clamp pressure, the material can be positioned prior to the welding process. By default, this pressure is considerably lower than the weld pressure and is intended to protect the operating person from crushing injuries.
