6.4 Welding parameters

• Set the potentiometer for the welding speed (17) to the required value.
• Set the air-blower switch (9) to position I. Adjust the air fl ow as required with the air slide (23). Adjust the
temperature as required with the potentiometer (24). The heat-up period is approx. 5 minutes.
• The contact pressure is aff ected by the weight of the automatic hot-air welding machine itself.
• Use the additional weight accessory as required (optional).

6.5 Tool positioning

• Swivel the hot air blower (4) up as far as the stop.
• Position the automatic welding machine on the overlap of the material to be welded. The outside edge of the
drive/pressure roller (2) must line up with the overlap edge of the material to be welded.
• The laser beam (22) must line up with the overlap edge of the material to be welded.

6.6 Welding procedure

Perform a test weld according to the welding instructions supplied by the material manufacturer and
conforming to national standards or guidelines. Check the test weld. Adapt the welding temperature
(welding parameters) as necessary.
• Swivel the hot-air blower (4) down under as far as the stop; the snap switch (21) automatically starts the motor
drive (the welding process starts).
• Supervise the welding process. Correct the welding speed with the potentiometer (17) as necessary. Guide the
automatic welding machine by the laser beam along the length of the overlap.
• When welding has fi nished, swing up the hot-air blower (4) as far as the stop.

6.7 Switching off

• Turn the potentiometer (24) to position 0 in order to cool down the hot-air blower (4). When the tool has cooled
down (after approx. 6 minutes), set the hot-air blower switch (9) to 0.
• Then disconnect the power supply cord (1) from the electricity supply.
• Wait for the device to cool down.
• Check the power supply cord (1) and plug for electrical and/or mechanical damage.
• Clean the welding nozzle (3) with a wire brush.
