Welding procedure
Perform a test welding according to the welding instructions of the material
manufacturer and the national standards or guidelines. Approve the test
welding.
· Set welding parameters drive, heating and blower (chapter 1, Work mode) ·
Welding temperature must be reached (heating up time approx. 3 – 5 min) · Pull
locking lever (11), lower hot-air blower (8) and move in welding nozzle (9)
between the overlapping
sheets as far as the limit stop; drive motor starts automatically
No automatic start, see Drive sensor adjustment section
· Machine can be started manually with the controls (4) Drive and e-Drive ·
The automatic hot-air welding machine is guided along the overlap at the guide
bar (27). Guide the automatic
hot-air welding machines without pressure onto the guide bar (27) during
welding. Pressure on the guide bar (27) can lead to welding errors. Observe
position of the guide roller (18) · After the welding pull locking lever (11),
move out hot-air blower (8) as far as the limit stop and swivel up to the
latching point
· After finishing the welding work, use e-Drive
(press 2 x) to switch off heating
In this way, the welding nozzle (9) is cooled down and the blower automatically switches off after
approx. 4 minutes (section 1.8, Cooling down)
· Turn off main switch (3) OFF
