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
(230V).
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.

vii. Welding parameters setting
1. Welding temperature setting:
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 setting:
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.

viii. Positioning the welder
1. Automatic Overlap Banner Welder
Keep both the edge of upper membrane and the side of guide wheel in the
same cord of the overlap pressure roller, shown as Figure 1.
2. Automatic Tape Banner Welder
Put the tape in the center of tape pressure roller, and the center of tape
should be put in the seam place of lower membrane. Meanwhile, keep the
side of guide wheel in the same cord of the seam place of lower
membrane, shown as Figure 2.
ix. 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 lift lever (23) to land down the roller
5. Press the control handle of guide wheel (12 ) to land down guide wheel ( 11 )
6. Lift the position handle of hot air blower (13) to lower down the hot air nozzle,
then move hot air nozzle to left and place it. The machine would start walking
and welding automatically.
7. To observe the relative position of Guide wheel (11). You can adjust the position
by flip the guide handle (20) if it deviates from the position.
8. When the welder walks into the end of material, lift up position handle of hot air
blower (13), move the hot air nozzle to the right until it cannot move, spin up and
lock it.

9. After finish the welding job, press the temperature setting knob- to make
the hot air blower in a cold blowing condition for 5 mins in order to cool the
nozzle. Then to power off the welder. If you want to keep the welding
temperature data, before you power off the welder, you can press down
both to cold the hot air nozzle in 5 mins. And press both when
you restart the welder.
x. Fault diagnosis and solved ways
The fault
performance
Caused reasons
Solved ways
Welder cannot walk
when hot air nozzle
at the right place
Micro switch is
not in right
place
Move the hot air nozzle to the left and
put it in place, then loosen adjusting
screw (17);
Move baffle of micro switch (18 ) , to
place micro switch ( 16 ) in the right
position
The position between
hot air nozzle and
drive roller is not
right
Adjust the fixed set ( left) of hot air
blower(14) and fixed set ( right ) of hot air
blower( by adjusting the screw under the
fixed set of hot air blower)
xi. Routine maintenance
