The machine switches on automatically after the blowers have been switched on:
• If the air temperature is higher than 100°C when the device is switched on – which can occur, for example, if the
device is disconnected from the power supply without cooling down – the device automatically switches to cool-
down mode. The cool-down process is finished when the air temperature is less than 100°C for 2 minutes.
Machine switches off automatically:
• In Standby operation, the heating is switched off automatically after the time elapses that the user has stored
(see also Standby mode [10.5]).
Welding result of deficient quality:
• Check drive speed, welding temperature and air volume.
• Clean the
welding nozzle (9) with a wire brush (see Maintenance [7.4])
• Welding nozzle (9) set incorrectly (see Setting the welding nozzles [5.1]).
If the set welding temperature still has not been reached after 5 minutes:
• Check the supply voltage
• Reduce the air volume
Device does not move forward in a straight line:
• Align the track guide roller (16) so that it is parallel and linear to the drive/pressure roller (8)
(see welding sequence [7.2]).
• Adjust the transport roller (13) to the movable transport axle (14)
(see Adjust the movable transportation axle [patent EP3 028 836 pending] [5.4])
