Product profile
It is a cost-effective and high-power plastic hot air blower developed by us. Only
one of the domestic similar products to adopt a single-chip precise temperature
control system, with a temperature accuracy of one degree error; Unique dual-digital
temperature control display, make sure the set temperature and real-time temperature
are clear at a glance; Use both temperature and air speed to be adjustable Mode to
meet the requirements of different air speeds; Only automatic delay shutdown design
is adopted to ensure that the gun core is forced to cool down after the shutdown.
Not only refers to the domestic and international general air duct and nozzle size
to ensure the versatility of the product; Also adopts pocket barrel design to meet the
convenience of domestic users to hold and meet the optimized ergonomic parameter
model . The body adopts lightweight design, low noise, large air volume, strong wind,
high power, fast heating, and long life.

Notes
1. Before operating, please read the instruction manual carefully, and ensure that the
safety regulations are complied;
2. The rated voltage is 220V, higher or lower than the rated voltage may cause
machine failure, and even cause irreparable damage, please check whether the
working voltage meets the requirements before use;
3. When using the machine on a construction site or outdoors, a leakage protection
circuit breaker must be installed(RCCB），in order to protect worker；
4. Damaged power cable may cause a fatal electric shock. Be sure to check the power
cable regularly. If it is damaged, it must be repaired or replaced by a professional
electrician. Otherwise, you cannot continue to use the machine;
5. If the casing is damaged or disassembled, it may cause a fatal electric shock. If you
need to repair, replace, and maintain the casing and internal parts of the casing, be
sure to unplug the plug from the socket first to ensure that the machine is in a
non-powered state;
6. Warning: Operating the machine in rain or humid environment may cause fatal
electric shock. Please ensure that the machine is stored and used in a dry environment;
7. Under normal use of the hot air blower, the temperature of the stainless steel air
duct and the nozzle is extremely high. Please make sure that the air nozzle is not
aimed at flammable and explosive objects, and that the air nozzle is not aimed at
children or other people's bodies; do not allow children or non-professional operators
to approach the machine; do not use the machine to heat liquids; no volatilization in
the working environment Flammable materials; stainless steel air ducts and nozzles at
work must not touch flammable and explosive objects;
8. Using this machine in a dusty environment is likely to cause machine failure or
even damage, which will make the machine to catch fire.

Operation & maintenance
1. Choose the correct nozzle according to requirements, and use tools to lock the
nozzle screw to prevent it from falling off suddenly during work;
2. Plug in the power supply, check the safety of the environment and check whether
the working voltage of the welding gun meets the requirements of the rated voltage;
3. Long press the POWER button for three seconds, the LED indicator will light up
and display "ON", and the machine will enter the working state;
4. Press the up and down arrow keys to adjust the set temperature. Long press is the
quick adjustment mode; The value on the red light is the set temperature value; the
value on the yellow light is the real-time temperature value;
5. Adjust the air volume & knob to the required air volume;
6. After use, press and hold the POWER button for three seconds, the LED will
display "OFF" and enter the shutdown mode. The machine will automatically
continue to blow cold air until the nozzle temperature drops to the design temperature,
and then automatically shut down.
7. When it is turned on again, the machine will directly memorize the temperature
value set last time, which is convenient to use and operate;
8. Regularly clean the dust on the air inlet filter with a small brush, and keep the air
inlet clean at any time;
9. Frequently clean stainless steel air ducts and nozzles to prevent clogging of the
nozzles and corrosion of stainless steel;
10. When the carbon brush is consumed to the min. length, the machine will
automatically stop. The service life of the carbon brush is about 1600 hours. If the
carbon brush requires to be replaced due to the consumption, please hand it over to a
professional electrician or maintenance company to replace a qualified carbon brush;
11. Make accurate use of the machine's automatic delayed cooling shutdown function,
and don’t forcibly unplug the power supply during the automatic cooling.
