  • Page 5: Overview Of Important Safety Instructions

    2. Overview of Important Safety Instructions 2.1 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.

  • Page 6: Intended Use

    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.

  • Page 8: Transportation Outside Of The Company's Premises

    To move the machine to the desired location on the respective company’s premises, the feet (8) must be turned upward as far as possible until there is no longer any contact with the floor and the machine rests on the floor with all three wheels.

  • Page 9: Securely Positioning The Machine

    Ensure that the machine is only operated in conditions with a maximum humidity of 80% and a maximum ambient tem- perature of 40°C. Individual components of the machine may no longer function properly if it is used above these limits. The operator of the machine is responsible for ensuring that the seat height provides the best possible view of the welding process and prevents posture problems.

  • Page 14: Air Outlet For Switch Cabinet Cooling

    7.2 Air Outlet for Switch Cabinet Cooling The switch cabinet has an integrated circulation system to cool the machine elements and prevent overheating. The cooling air is drawn in at point 17 and the warm exhaust air is discharged at point 18. These openings must be kept clear at all times to avoid obstructing the air circulation.

  • Page 15: Emergency Stop Button Function

    7.4.1 Emergency Stop Button Function Pressing the emergency stop button during the welding process interrupts the current supply. No axis movements are performed and the power supply to the hot wedge stops immediately. Please note that the hot wedge (22), hot- wedge holder (3) and bracket fixture (2) may still remain hot for a long time.

  • Page 16: Feet

    7.7 Feet Turn the feet (8) downward equally in order to position the machine securely on the ground. Ensure that the machine is suitably and securely positioned before it is commissioned. Use a spirit level to align the machine. Then lock the threaded rods against the machine frame using the lock nuts.

  • Page 17: Changing Welding Arm And Welding Arm Options

    7.9 Changing Welding Arm and Welding Arm Options Caution: To activate the desired welding arm, the motor icon (M) must be switched off. Make sure that the correct welding arm is selected to prevent damage to the drive and hazardous situa- tions.

  • Page 18: Quickarm

    7.9.3 Quickarm activate Make sure that the upper transport roller is open (see Chapter 7.9.1). Hold the quickarm (15) and pull the upper re- taining pin (15A) out to disengage the locking mechanism for the quickarm. Now carefully fold the arm downward and fit the lower retaining pin (15B) until it fully engages.

  • Page 19: Changing The Transport Rollers

    7.10.1 Changing the Transport Rollers Caution: Allow all components to cool down before changing the transport rollers in order to prevent burns. Changing the transport rollers In the "Periphery" area, set the wedge and the clamp force to "Manual" and "Off". Risk of crushing Danger: Do not reach between moving components, e.g., the transport rollers (4).

  • Page 20: Guide Holder

    Once the guide and the welding wedge (22) have been adjusted, check that the hot wedge does not touch anything when swiveling in and out. Different guides are available as accessories. Ask your Leister sales partner about the numerous options available.

  • Page 21: Hot Wedge

    8. Hot Wedge 8.1 Wedge Types There are two different types of wedge; which one is used depends on the intended purpose and the required speed. The engraving on the wedge holder (3) indicates the type in question. The number indicates the welding width. The maximum possible welding speed depends on the welding holder that is mounted.

  • Page 22: Wedge Cleaning

    8.2 Wedge Cleaning When the wedge is positioned properly and the welding parameters are set correctly, very little slag is formed. It is mainly limited to the front part of the wedge (22). If an excessive amount of slag is formed, readjust the wedge and reduce the energy value.

  • Page 23: Adjusting The Welding Wedge Height

    8.4 Adjusting the Welding Wedge Height Slight differences in height are automatically adjusted by the bracket fixture. Nevertheless, the height of the hot wedge must be checked and – if necessary – adjusted every time the wedge holder is changed. Locking screw 2C can be used to adjust the height of the wedge holder/wedge.

This step is very important as the software will use this information to calculate the required welding energy in relation to the speed.

  • Page 35: Positioning The Welding Wedge

    Resistance check In this step, the resistance of the hot wedge is checked and compared to the installed data. If the actual resistance de- viates too much from the target resistance, the orange or red lamp will light up in the traffic light indicator. In this case, please check whether the hot wedge has been mounted correctly, whether the right welding holder/welding width has been selected, and whether the contact surfaces are free from contamination (see Chapter 8).
