IV. MAINTENANCE & PRECAUTIONS
Hot Air Rework Station
4. Keep a minimum distance of 2mm between the object and the hot air gun’s air outlet.
5. DO NOT allow the hot air to come in direct contact with facial parts, and beware of the danger
of burn injuries. Upon the first use, the hot air gun may emit white fumes, and the white fume
will dissipate in a short while.
NOTE:
The station’s hot air gun and soldering iron handles use high-strength stainless steel tubes. The station
goes through 4 times or more testing, inspection, and calibration procedures before rolling off the ass-
embly line. The steel tube may exhibit light bronze color as a result of our quality control efforts. It is n-
ormal to have a slightly bronzed steel tube when using a brand-new station, rest assured for regular us-
age.
5-1. Once the hot air temperature stabilizes, press and hold both the hot air rework station’s
temperature increase and decrease buttons for approximately 2 seconds. The display will
show the set temperature while showing 3 digit-dots.
5-2. Press the hot air rework station’s temperature increase or decrease button to enter the
measured hot air temperature value.
5-3. Press and hold both the hot air rework station’s temperature increase and decrease butt-
ons for approximately 2 seconds to confirm entry. The system will automatically correct
the temperature discrepancies and exit the calibration interface.
Soldering Station
1. Connect the soldering iron to the station, and place the iron into its holder.
2. Turn ON the station’s master power switch located at the rear of the station, and then turn ON
the soldering station’s power switch. The soldering station’s heating element will begin heatin-
g, and its operation indicator light will turn ON. The operation indicator light will stay constant-
ly ON when the soldering iron is heating up, blink rapidly when the temperature stabilizes, and
be turned OFF when the soldering iron is cooling. Begin your operation once the soldering stat-
ion’s indicator is blinking rapidly to indicate the temperature’s stabilization.
CAUTION: Upon the first use of the soldering iron tip, set the temperature to 250°C/482°F. When the
iron is just hot enough to melt the solder, coat the tip with a layer of solder (the use of rosin core sol-
der is recommended), then set the temperature to your desired value.
3. When the operation is complete, use a wet sponge or metal wool ball to clean the soldering ir-
on tip. Tin the tip with a new layer of solder, then put the soldering iron back to its holder and
turn OFF the power switch. If the station is not in use for an extended period, turn OFF the ma-
ster switch and DISCONNECT the power cord.
Indicator for real-time temperature
tracking & compensation
1. Keep the air outlet clear and free of blockages at all times.
2. The installation of the hot air gun nozzles MUST be carried out ONLY when the steel pipe and
nozzle have cooled. Install the nozzle correctly, DO NOT install the nozzle with brute force, pull
the edge of the nozzle with tweezers, or over-tighten the screws.
3. Select the appropriate nozzle based on your operation requirement ( temperature may vary
when using nozzles in different diameters). When using nozzles smaller than the standard ma-
chine nozzles, you MUST use the maximum air volume with a relatively lower temperature set-
ting. Complete this operation in the shortest possible duration to avoid damaging the hot air
gun.
Soldering Station
1. If a layer of oxidization forms on the surface of the soldering iron tip, a misconception can be
created that the soldering tip cannot heat up properly to melt the solder and do the tinning.
However, the actual temperatures of both the heating element and soldering tip are high. In
such an instance, please do not increase the temperature value confusedly but use a metal w-
ool ball to remove the oxidization following the steps below:
A. Set the temperature to 300°C (572°F).
B. Once the temperature has stabilized, gently rub the soldering iron tip inside the metal wool ball.
C. When the oxidization is partially removed, continue applying solder onto the tip while rubbing it until
the solder completely adheres to soldering iron tip. If the tip is too severely oxidized beyond cleaning,
replace the tip with a new one.
2. DO NOT use metal files to remove the oxidization on the soldering iron tip. If the soldering iron
tip deforms or rusts, replace it with a new tip.
3. DO NOT apply excessive force on the soldering tip when soldering. Doing so will not only dam-
age the iron tip but also not improve the heat transfer.
4. When placing the soldering iron back in its holder to idle after a high-temperature operation,
adjust the temperature to 250°C (482°F) or below for idling. Failure to do so, and leaving the s-
oldering iron tip to idle on a high-temperature setting will cause the accelerated aging of the
heating element, and shorten the lifespan of the heating element and soldering iron tip.
5. After every operation, always clean the soldering iron tip, then coat it with a layer of solder to
prevent its oxidization.
V. TROUBLESHOOTING GUIDE
1. “S-E” – This is an indication that the station’s sensor module is faulty. To resolve this issue, you
need to replace the heating element (the heating element and the sensor modules).
2. When replacing the heating element, take note of the original connecting order and colors of
the wires which MUST NOT be connected incorrectly.
