Welding Workflow
• Preparation
Carry out a test weld according to the welding instruction of the material manufacturer and
national standards or guidelines. Check test weld.
– Set welding parameters for drive, heating and blower (see Section 1, Work Mode).
– Welding temperature must be reached (heating up time approx. 1–2 min.).
• Start welding
– Swivel guide roller (15) downwards.
– Swivel hot-air blower (8) gently open and in until the locking cam (10) is pushed out of the recess.
Immediately lower the hot-air blower (8).
WARNING: If the hot-air blower (8) is pushed in too far, the welding nozzle (9) and pressure roller (11) will
come into contact. The hot-air blower (8) cannot then be lowered.
– Lift upper tarpaulin material slightly in the area of the guide roller and move the welding nozzle (9) between
the overlapping tarpaulins as far as the limit stop by pushing the hot-air blower (8).

– Drive motor starts automatically. No automatic start (Section FAQ, page 35).
– The machine can be started manually with the controls (4) Drive
– If the drive is started via
machine will continue operating for about 30 cm after the welding nozzle (9) has been swivelled out (delayed
deactivation of the drive).
– The hot-air welding machine can be guided along the overlap at the guide bar handle (33), carrying handle (17)
or holding handle (28). Guide the hot-air welding machine without pressure onto the guide bar handle (33),
carrying handle (17) or holding handle (28) during welding. Pressure can lead to welding faults.
Observe position of the guide roller (15).
• End of welding
– After welding, push the welding nozzle (9) out from the welding position to the right using the hot-air
blower (8) and raise.
– Push hot-air blower (8) to the right until the locking cam (10) latches into the recess of the holding
handle (28). The hot-air blower (8) is in the parked position.
– Swivel guide roller (15) upwards.
9
– Lowering the transport rollers (26) by swivelling the handle (27). The
pressure roller (11) and diverting roller (12) are relieved for transport
in this way.
– After finishing the welding work using the e-Drive
the welding nozzle (9) and the blower switches off automatically after approx. 4 minutes (Section 1.8, Cooling).
– Turn off main switch (3)
