i. Applications:
It can be applicable for welding PVC-P、PE、TPO、ECB、CSPE、EPDM、PVDF and other
Coated fabric covering, foil and homogeneous or coating sealing film and PE coating fabric.
ii. Notice:
1. Unplug the tools before opening it to avoid of being hurt by exposed wires or component
inside the machine with power
2. Incorrect use of it can cause fire and explosion hazard because of high temperature,
especially near combustible materials and explosive gases.
3. Don’t touch heater tube and nozzle when they are hot. They may cause burns. Don’t point
hot air flow in the direction of people or animals.
4. The voltage rating stated on the welder must correspond to line/mains voltage (220V or
110V).
The drop cable / wire with protective earthed conductors can only be used.
5. To ensure operator safety and reliable operation of equipment, the power supply must be
installed power supply and leakage protection at the construction site.
6. It must be running at the correct use of manipulation of the operator, or they may cause a
fire or explosion caused by high temperature.
7. Don’t use welder in the water, or on a muddy construction site, to avoid flooding, rain or
moisture.

v. Controller Panel
●ON/OFF switch（8）is used for
open the main power of the welder
●Open ON/OFF switch (8),
LCD display is shown as figure 1,
the hot air blower is under natural
wind without heating.
●Press the button (7) and
(6), the screen shows as Figure 2
and the hot air blower starts to heat until to
the setting temperature.
If press the bottoms (7) and (6) at the same time,
LCD display shows as figure 1, the hot air blower is under natural wind without heating.
●When the welding nozzle is at the right position, press the moving switch (9) and the welder
starts to move and weld. It will stop move if you press the moving switch again.
●When the welder starts to move, the LCD display shows as figure 3.

VII. Positioning the welder：
Pressure Lift lever (23) to lift machine, move it to welding position (the edge of upper
membrane should keep in
the same alignment with
Drive silica roller (21) and
the edge of Guide wheel
(15) ), as shown in figure 4.
Fig 4
1. Welding temperature:：
Using bottoms Temperature setting knob+ and Temperature setting knob-
on the panel to set the required temperature. You can set the temperature according to
the welding materials and the ambient temperature. LCD display will show the set
temperature and the current actual temperature.
2. Welding speed:
Using bottoms Speed setting knob+ and Speed setting knob - on the panel
to set the required speed according to the welding temperature. LCD display will show
the set speed and the current actual speed.
3.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 to re-set
parameters.

Welding process
1. Setting the welding parameters according to the data of welding test.
2. Please wait the actual temperature value reaching the setting value.
3. Positioning the welder
4. Lift the operating handle (13) to lower down the hot air nozzle (19) to close the down
membrane, counterclockwise Operating handle (13) to place hot air nozzle into the
overlap membrane. The machine would start walking and welding automatically.
5. To observe the relative position of Guide wheel（15）.
6. When the welder walks into the end of material, clockwise the operating handle (13) to pull
the hot air nozzle to right side. Then pressure the operating handle (13) to lift the hot air
nozzle.
7.
8. After finish the welding job, press the Temperature setting knob+ and
Temperature setting knob- to make the hot air blower in a cold blowing condition in
order to cool the nozzle.
VIII. Using Condition：
1. The distance between hot air nozzle and ground should be shown as figure 5（We have
adjusted the distance）.
2. The distance between hot air nozzle and Drive roller should be shown as figure 6（We have
adjusted the distance）. You can adjust Hot air nozzle adjusting screw (28) if the distance is
not right.
