12.1 Work environment and safety
Power supply cord and extension cable
• The nominal voltage specifi ed on the device (see technical data) must match the mains voltage.
• The power supply cord (1) must be able to move freely and must not hinder the user or third parties during
work (danger of tripping).
• The extension cables must be authorized for the utilization site (e.g. outdoors) and be marked accordingly. Ob-
serve the necessary minimum cross-section for extension cables as required.
Power plants for energy supply
When using power plants as an energy supply, please ensure that the power plants are grounded and equipped
with earth leakage circuit breakers.
For the nominal output of the power plants, the formula 2 x nominal output of the hot air welder applies.
12.2 Operating readiness
Hook up the strain relief of the power supply cord (1) in the spiral holder (25) and afterwards check the basic
setting of the welding nozzle (9).
12.3 Position the device
• Check whether the material to be welded is clean, not only between the overlap but also on the upper and lower
sides.
• Afterwards, check whether the welding nozzle (9), the drive/pressure roller (8), the defl ection roller (27)
and the downholder belt (26) are clean.
• Swivel the hot-air blowers (10) so that they engage in parking position.
• Now raise up the hot air welder by the guide bar (22, 24) and move the device to the desired welding position.
• Now position the welding plate (see scope of delivery) and then swivel the track guide roller (16) downwards.
• Take care to ensure that the track guide roller (16) is positioned parallel to the drive/pressure roller (8).
