Operation
Operating condition
• Before putting into operation, check power supply cord (2) and connector as well as
extension cable for electrical and mechanical damage.
• Check the nozzle's basic setting (see diagram).
Connect tool to rated voltage.

FI
Rated voltage stated on the device must correspond to line/mains voltage.

Extract hot-air blower in case of power breakdown.
Operating Instructions
• Perform a test welding according to the welding instructions of the material manufacturer and the national
standards or guidelines. Check the test welding. Adapt the welding temperature (welding parameters) as
required.
Tool positioning
• Swivel hot air blower (3) using swivel lever (20) up to the stop.
• Operate lifting device (11) by means of lifting device lever (14) so that drive/pressure roller (6) and drive
roller (9) are at no-load.
• Position the automatic welding machine on the overlap of the material to be welded. The outside edge of
drive/pressure roller (6) must line up with the overlap edge of the material to be welded.
• Activate lifting device (11) by means of lifting device lever (14) so that the automatic welder is ready to run.
Welding parameters
• Set potentiometer for welding speed (16) to the required value.
• Set potentiometer for air flow (18) to the required value.
• Turn on air blower switch (17). Set the two stage switch for airflow (19) at setting 3 and heat up for about 5
minutes.
• Important: low voltage.
If the maximum temperature is not reached, reduce the airflow by means of the manual air valve (13) and two
stage switch for airflow (19).
• The contact pressure is effected through the weight of the automatic hot air welding machine itself. Use the
additional weight accessory as required (see assembly of additional weight, page 13).
Welding procedure
• Swivel the hot air blower (3) up to the stop using swivel lever (20) and at the same time turn on the drive
switch (15) (the welding process starts).
• Supervise the welding process. As necessary correct the welding speed with the potentiometer (16). Lead the
automatic welding machine by its chassis along the length of the overlap.
• When welding has finished, swing up the hot air blower (3) to the stop by means of the swivel lever (20).
• Switch off the drive switch (15).
• After completing welding work, set the potentiometer for air temperature (18) to zero, so that the hot air
blower (3) cools down. Then turn off the air blower switch (17).
