Device Positioning

• The tarpaulin material must be clean between the overlap and on the upper and lower side.

• The welding nozzle (9),pressure roller (11),diverting roller (12),round belt (23) and hold-down device

(13) must be clean.

• If the hot-air welding machine is not ready for transport, lift up device using the handle (27) of the lifting

device. The transport rollers (26) are now functioning.

• Move hot-air welding machine to welding position.

• Lower the hot-air welding machine into the welding position with the handle (27). The transport rollers (26) no

longer function and are thus relieved.

• Swivel guide roller (15) downwards.

• The guide roller (15) must be parallel to the pressure roller (11) (Detail C). Detail C

Connect device to nominal voltage. The nominal voltage indicated on the device must correspond to

the mains voltage.

Move hot-air blower (8) out to parked position if the mains power fails.

•Install guide bar with cheese head screws (18).

– Move the guide bar bottom (19) into the required position using the

screw lever (24) and the guide bar top (20) using the clamping lever (21).

– Hang strain relief of power supply cord (1) into holder (22) on the guide bar or on

the carriage.

Operational Availability

• Before putting into operation, check power supply cord (1) and connector as well as extension cable for

electrical and mechanical damage.

• The default setting for the welding nozzle (9) is made at the factory.

• Check the default setting of the welding nozzle (9).

– The check can be made using the nozzle gauge (34) or corresponding to Detail A and B.

– Drive motor starts automatically. No automatic start (Section FAQ, page 35).

– The machine can be started manually with the controls (4) Drive and e-Drive .

– If the drive is started via and e-Drive and the welding nozzle (9) is then pushed in, the hot-air welding

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.

– After finishing the welding work using the e-Drive (press twice) switch off the heating; this cools down

the welding nozzle (9) and the blower switches off automatically after approx. 4 minutes (Section 1.8, Cooling).

– Turn off main switch (3)

Disconnect power supply cord from power supply.

– Clean welding nozzle (9) with brass brush.

• 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).

1.2 Work display

• Pressing the e-Drive starts the heating and blower and the Setpoint

Value display changes to the Work display.

• When the welding nozzle (9) is heating up, this is indicated on the

display (5) with a progress bar, arrow (up) and the actual value of

the welding temperature (flashing) (Fig. 5).

Once the setpoint value of the welding temperature is reached,

the arrow and progress bar will no longer be displayed (Fig. 6).

• If the mains voltage is outside (+/- 15%) the specified nominal

voltage, the symbol will be displayed alternately with the measured

undervoltage /overvoltage and the set air volume. If the air

volume is 100 %, the symbol will be displayed flashing with the

measured undervoltage /overvoltage (Fig. 7).

(Only possible with VARIANT T1 230 V~).

Undervoltage/Overvoltage can affect the welding results!

• If no button is pressed after a definite time (welding nozzle (9)

NOT in welding position), the Standby menu will be displayed

(Section 1.9 Standby).

• If the welding nozzle (9) is in the parked position, the menus Cool Down (Section 1.8 Cooling) or Profiles

(Section 1.7 Selecting Profiles) can be selected by turning the e-Drive .

•

If the welding nozzle (9) is swivelled in, the two menu items will disappear on the display (5)

and can no longer be selected

• While the welding nozzle (9) is cooling down, this is indicated with a filled out progress bar,

arrow (down) and flashing actual value of the welding temperature on the display (5) (Fig. 8)

• The heating, blower and drive are switched off in this menu.

• Here the user can perform all settings described in the following sections using the

controls (4).

• If, however, the heating element temperature is greater than 80°C when switching on,

the display will immediately change to the Cool Down mode (Section 1.8 Cooling)

in which the blower is always operated at full power, thus cooling down the

welding nozzle (9). You can change back to the Work Mode from this mode at any

time by pressing the e-Drive .

• If the heating element temperature reaches 60°C during cooling, the blower will

continue to operate for 2 minutes and then switch off automatically. The display (5)

changes back to the Setpoint Value display (Fig. 3).
