Can be effective to avoid hot air gun handle caused by fire or other accidents. Select the manual function: When the gun handle back on the holder, that the gun is not cool and keep in work. Its very suitable for frequent operation and save cooling and heating time to improve work efficiency, itis recommended to use the manual function status was finished, please switching back to the automatic function to improve safety! (see specific settings feature set)
  1. Temperature correction function: Adapted due to environmental conditions or the replace the heater/ fan blower / iron tips caused by iron or hot air gun temperature deviation, this feature can be corrected temperature. Correction of temperature (See the specific set of feature set)
  2. Celsius/ Fahrenheit temperature display function: Meet different market needs to design the temperature display mode. According to the custom to choose. (See the specific set of feature set)
  3. Iron sleep function: Iron automatic detection self working condition, when not in use is at a standstill. Reaches the set time to sleep, iron temperature automatic cooling to 2000C enter sleep state. Which can effectively prevent the iron tips oxidation and prolong the service life, energy saving and environmental protection. Sleep time can be provided with a range of powerful, can set range: 0 —99 minutes, walking for 1 minutes, the user can use to set.
    if you don't want to sleep, can be set the sleep time at 0. (See the specific set of feature set)
  4. Air gun with a protective function: lf the guns in the using process of the non normal stop wind, that heater will stop heating to prevent gun burn out by non wind, enhancing the safety performance of the product.
  1. Iron part adopts import heater, quick temperature rise, temperature stability, long service life, static design, prevent electrostatic damage the SMD element.

Operating Instructions

Hot air rework operation

  1. Desoldering station will be a good place, first please install air gun frame in the left of the machine, then the handle must be set in the handle frame, otherwise air gun will not work ( it has the unique security features, effective prevention of air gun in unknown circumstances on hold in other parts of fire or other accidents).
  2. Connected power supply, the device the air nozzle (to make use of large - diameter nozzle).
  3. Open the back of the chassis whole switch, the display shows the factory default values, the temperature of the air gun display windows - ' when the air gun for standby, pick up the handle, rework station hot air guns enter into the state of the normal heating, at this time the air gun indicator ( air gun display window of the lower right corner) is on! Warming up the indicating lamp bright, constant temperature the indicating lamp will regular high flicker, cooling the indicating lamp off. Adjusting airflow knob setting appropriate airflow, stay stable temperature will be normal operation. After the thermostat can visually see indicating lamp flashing at high speed, and then high precision PID program in milliseconds to high-sepeed tracking and compensate the gun actual temperature. So that the gun into the high stability and high precision constant temperature condition! (Figure 2)
    Hot air rework operation
  1. Work is completed, must be put the handle on the holder, at this time desoldering will automatic cut off the heating current into the body to send cold air cooling heating mode. When the temperature is below 100ºC shows de-soldering station, that means the machine will enter into standby mode. the machine enter into standby state, press air gun " POWER " button turn off air gun.lf long time no use, please turn off the back of the chassis whole switch.

Terms Of Use

  1. When turning on the main unit's power, the Hot Air rework's handle must be placed properly on the handle's rack.
  2. Please ensure the Hot Air's outlet is clear, must free from any blockages or obstructions.
  3. After usage, the handle must be placed back on the handle's rack, let the unit cooling down (temperature gradually decreasing) until it displays "---" (Air flow stop), then turn off the HotAir power switch.
  4. The unit comes with 3 standard nozzle sizes: Large, medium, small. When using the smaller nozzle the hot air volume must be adjusted to the maximum rate or set the temperature low and maintain it in short time, to avoid prolonged use which could damage the Hot Air unit.
  5. In regards to the usage requirements, choose the appropriate Hot Air flow, different Hot Airflow will cause the temperature to be slightly different, and please maintain the distance between the outlet and the object must be at least 2mm.
  6. When the iron is used for the first time, please pay attention to check the iron tip warming condition, when the tip can melt the tin wire, please plate some tin on tip, then adjust to the desired temperature.
  7. The tip temperature should not be too high, too high temperature would weaken the tip function. When interval using, can lowering the temperature.
  8. Should be regularly use clean sponge to clear soldering tip, after finish use, should wipe clean soldering iron tip, plate new tin to prevent soldering iron tip oxide.
  9. After prolonged use, the inlet of the air gun handle may be sticking a lot of dust blocking the vents, please clean-up it, to avoid to reducing outlet airflow. Another thing: Fan may be the effect of variation of lubrication and dust impact, resulting in the fan slowly rotating, the program may start no wind protection function does not work, timely maintenance of the fan.

Special instructions: Dear User! Our air gun and soldering iron handle adopt high strength stainless steel tube, the machine must be inspected or calibrated four times in normal working condition during the production process, the copper tube could be slight yellowing due to high temperature! When use the new machine first time, it is normal that the steel tube at a slight yellowing, please be assured!

The do's and don'ts

  1. Do not rude when put on nozzle or use pliers to pull nozzle edge, Do not hard to bolts screws.
  1. Nozzle can be install after the heating pipe and nozzle are cool.
  2. High temperature can burn the human body, do not touch the heating pipes, or put the heat air spurting to face. At the starting, may be emitted white smoke, this is a normal phenomenon, this phenomenon will disappear later.
  3. When replace the heating element, be careful don't damage the ground wire.
  4. When doing replacement, should pay attention to the order and color of the connecting wire, it could not be wrong connection!
  5. Please replace the same type of heating element or heater!

Display Notes

  1. When the LED digital display - ", it means the outlet temperature is below 100ºC; the hot air rework station is in standby mode, and the handle is placed on the handle's rack.
  2. When the LED digital displays "S-E", it means the Soldering iron and Hot Air rework's sensor is having a problem or handle is un-plugged, if this the case it needs to replace the heating element (heating core's element and sensor components).
  3. Display "F-1/F-2", shows the air gun is no wind protection, you need to check the fan and air gun power supply circuit.
