Operating Instructions (Translation of the original operating instructions)
Please read operating instructions carefully before use and keep for future reference.
Leister BITUMAT B2
Hot air welder

Application

Handheld hot air welder for overlap welding of modified bitumen membrane liners (SBS, APP) in the open air or in well ventilated rooms, for various roof systems, on horizontal and shallow-pitched flat surfaces.
Warning
Danger to life when opening the device as live components and connections are exposed. Unplug the line/mains plug from the plug socket before opening the device.
Incorrect use of the hot air tool can present a fire and explosion hazard especially near  combustable materials and explosive gases.
 Do not touch hot welding nozzle, they can cause burns. Allow the tool to cool down. Do not point the hot air flow in direction of people or animals.
Connect tool to a receptacle with protective earth terminal. Any interruption of the protective earth conductor inside or outside the tool is dangerous !
Use only extension cables/cords with protective earth conductor!
Caution
Rated voltage stated on the device must correspond to line/mains voltage.
N 61000-3-11; Zmax = 0.105 Ω + j 0.066 Ω. If necessary, consultate supply authority.
In the case of line/mains power failure extract hot air blower and set main switch to position 0
For personal protection, we strongly recommend the tool be connected to an RCCB (Residual Current Circuit Breaker) before using it on construction sites.

Welding parameters

Welding temperature
** Turn the main switch (3) to I. Set the temperature knob (6) to the required value. Heating-up time approx. 5 minutes. Air volume**

• To achieve optimum welding of the modified bitumen membrane liners or to avoid bitumen spatters, the air volume can be set with the turning knob for air volume (32).

CAUTION: If the quantity of air flow is reduced, the temperature knop (6) may not be set higher than stage 8.
Risk of overheating the heating element.
Welding speed
Set the appropriate welding speed with the speed knob (5) depending on the sealing sheeting and weather conditions. Joining force

• The joining force is transmitted to the drive roller (13).
• The replacement drive roller (22) and the screw-on additional weight (23) can be removed as required (see joining force table).

With screw-on additional weight (23) and without replacement drive roller (22)| 180 N| 180 N
Replacement drive roller (22) and without screw-on additional weight (23)| 205 N| 210 N
Replacement drive roller (22) and with screw-on additional weight (23)| 225 N| 230 N

CAUTION: The replacement drive roller (22) must during transport always be secured with the screwon additional weight (23) to be in the holder (27).

Operating preparation

• Before putting into operation, check power supply cord (1) and connector as well as extension cable for electrical and mechanical damage.

• Move lower guide bar (15) into the required position using clamping screw, lower guide bar (17) and upper guide bar (33) using clamping lever, upper guide bar (16).

• Clip strain relief of power supply cord (1) in holder (18).

• Check the basic setting of the welding nozzle (7).
  – The welding nozzle (7) must lie flat on the lower membrane liners (see Detail A).
  – The distance between the centre of the drive roller (13) and the air outlet of the welding nozzle (7) should be 80 mm (see Detail B). Otherwise the hot air blower (8) must be set with the scale for tool adjustment (12) by loosening the screws (24).
  – The welding nozzle (7) should be set parallel with the drive roller (13

• Transport configuration
  – Swivel the guide roller (19) upwards
  – Extend the hot air blower (8) by pulling the locking lever (10) and swivelling it up until it locks in place.

• Set the guide roller (19) to the required overlap using the guide roller adjusting screw (20).

• The distance between Guide roller (19) and Drive roller (13) is 5 mm (Detail C).

Detail A

Detail B

Detail C

• To achieve an even weld, there must be no bitumen deposits on the drive roller (13).

• In the case of soiling, the following measures can be taken:
  – Release screws for scraper (26). Reduce the distance between the scraper (25) and the drive roller (13).
  Tighten the screws for scraper (26).
  – Release the fastening screw (14), remove and clean the drive roller (13). Mount the drive roller (13). Tighten the fastening screw (14).
  – Release the fastening screw (14) and remove the drive roller (13). Release the Screw-on additional weight (23), remove the replacement drive roller (22) from the holder (27). Mount the replacement drive roller (22) with the fastening screw (14). Place the soiled drive roller (13) into the holder (27) and secure with the Screw-on additional weight (23).

• Connect tool to rated voltage.

  Rated voltage stated on the device must correspond to line/mains voltage.
Without lifting deviceWith lifting device

Power supply

If an extension cable is used, a 3 × 4 mm² mains cable must be used. The extension cable must be approved for the application site (e.g. outdoors) and labelled accordingly.
Heating power at +/- 10 % the rated voltage

Undervoltage has a negative effect on the welding speed and quality !
Tool positioning without lifting device

• Lift hot air welder applying pressure onto upper guide bar (33) and move to weld position
• Swivel the guide roller (19) downwards.
• The distance between Guide roller (19) and Drive roller (13) is 5 mm (Detail C).

Welding process without lifting device

• Set the welding parameters, see Page 19.
• **** The welding temperature must be attained (heating-up time approx. 5 minutes).
• Perform a test welding according to the welding instructions of the material manufacturer and the national standards or guidelines. Approve the test welding.
• Raise the locking lever (10), lower the hot air blower (8) and move it in between the overlapping membrane liners to the end stop. Wait a moment until the material is plasticized.
• Start the drive with the drive switch (4). In case of mains power failure, the drive switch (4) switches off automatically. Once mains power is restored the drive can be restarted.
• The hot air welder is guided along the overlap at the upper guide bar (33). Do not apply any pressure to the upper guide bar (33); this could lead to welding errors. Observe the position of the guide roller (19).
• After welding pull locking lever (10), move out hot air blower (8) as far as the end stop and swivel up to the latching point, at the same time switch off drive switch (4).
• **** On completion of welding work, set the temperature knob (6) to zero; this cools the welding nozzle (7).
• Set the main switch (3) to 0.
• In the case of line/mains power failure extract hot air blower (8) and set main switch (3) to position 0
• Disconnect power supply cord (1) form the line/mains.
