3、Press the temperature up button and the temperature down button simultaneously.
The display shows as Figure 2.At this time, the air blower starts to heat up to the
setting temperature.
4、Press the temperature up button and the temperature down button simultaneously
again. At this time, the air blower stop heating and is blowing natural wind.
5、Press the Run Switch when the welding nozzle is in the welding position, the drive
wheel and the pressure roller start to rotate, and when the Run Switch is pressed
again, the rotation stops.
6、When the machine begins to walk, the display shows as Figure 3.
7、Air Volume Knob: control the amount of airflow, increase the air volume clockwise,
and reduce the air volume counterclockwise.

1、Welding Temperature：
Use bottoms to set the welding temperature according to the welded
materials and ambient temperature. The LCD screen shows the setting temperature
and current temperature.
2、Welding Speed：
Use bottoms to set the welding speed.The specific speed should match
the welding temperature. The LCD screen shows the setting speed and current speed.
3、Air Volume ：
Use the knob to set air volume. Increase the air volume clockwise and reduce
the air volume counterclockwise.The maximum air volume can be used under normal
conditions. When the ambient temperature is too low and the current temperature
does not reach the set temperature, the air volume can be appropriately reduced.
● The machine has a memory function parameters, namely when you use the welder
next time, the welder will automatically use the last set of parameters without having t

Welding and Adjustment Process Operations
1、Loosen 1 move 2, lock 1 when the distance A between the edge of 2 and the edge
of 8 match the welding requires.
2、Loosen 9 adjust the position of 10 to align the right edge of 10 with the left edge
of 8.
3、Loosen 2 move 5 to drive 4, lock 3 when the distance B between the edge of 4 and
the edge of 8 match the welding requires. This can make 4 better position and
guidance in the rope welding.
4、Press the operation lever 6 down to press the upper pressure roller 7.
5、Step on the foot pedal 11, the welding nozzle 12 is in position with the air blower,
and then the foot pedal 11 is depressed, and the welding nozzle 12 leaves the
working position.
The membrane and
the limit pad should
be aligned
It needs the insulated plug to
block the rope guide tube to
prevent the hot air flowing back
from the rope guide tube( not in
the rope welding situation)
The pressure roller should be close to the
membrane to limit and guide

Welding Steps
Welding Precautions
LST-PAU
LESITE
1、Adjust the corresponding position of the guide as described in point 7 and as needed.
It needs the insulated plug to block the rope guide tube when it is not doing the rope
welding.
2、Turn on the machine, setting the temperature, speed and air volume as described in
point 6.
3、Pass the material to be welded through the hem guide device and press the operating
lever until the pressing wheel presses the material to be welded..
4、When the current temperature displayed on the screen reaches the desired
temperature, press the foot pedal,the welding nozzle is moved to the working position,
and the driving wheel and the pressing wheel start to rotate and drive the material to
be welded for welding.
5、Repress foot pedal after the welding is completed, the welding nozzle will leave the
working position, and the driving wheel and the pressing wheel stop rotating.
1、Please be noticed: Before starting the welding, it must be ensured that the welding
preheating temperature has been reached, and the general heating time takes 3-5
minutes.
2、For the change of different specifications and materials, the welding test shall be
carried out according to the welding procedure of the material manufacturer and the
national standard or regulations before welding, and the test results shall be tested.
After achieving satisfactory results, mass production begins. If necessary, adjust the
process according to the test results.
3、Since the fabric is soft and easy to move, it is necessary to manually assist the edge of
the flange to abut the limit of the hem guide device during the welding process.
Maintain proper tension on the fabric throughout the welding process.
4、When the machine is turned on and the work button or the foot pedal is pressed, the
hot air blower will automatically sway into the nozzle and will protrude between the
base material and the flange, and the drive motor will automatically open. Therefore, it
is necessary to install the welding cloth clamping roller before this.
5、After the welding is completed, the foot pedal is stepped on again, and the air blower
will automatically lift up and leave the welding position. The drive motor stops
automatically. The heating should be turned off at this time. Wait for the hot air blower
to cool down before turning off it.
6、To fold the outer cover of the machine, please disconnect the power supply first.
Avoid injury.
7、Pay attention to the local power supply voltage in accordance with the nominal voltage
of the machine. Over-voltage and under-voltage can cause damage to the machine.
