JBC JNA High-Precision Hot Air Control Unit Instruction Manual

JNA High-Precision Hot Air Control Unit

Product Information:

The JNA High-Precision Hot Air Control Unit is a high-quality
hot air control unit designed for precise temperature control. It
comes in three different voltage options: JNA-1UB (120V), JNA-2UB
(230V), and JNA-9UB (100V).

The product features a display screen, pick and place activation
switch, T260 pick & place handle, J125 cartridge range, USB-A
connector, main switch, NH high-precision heater hose set, NAS
stand for NH high-precision heater hose set, power socket, fuse,
USB connector, equipotential connector, and pedal connector. Some
accessories mentioned in the manual, such as the adjustable stand
and cartridges, are sold separately.

The JNA offers an intuitive user interface with quick access to
station parameters. The default PIN is 0105. It also provides
information on power supplied to the heater, current air
temperature, selected air temperature, hot air temperature,
selected air flow, and station information. The menu options allow
users to set station parameters, tool parameters, view hours worked
in each cycle, choose the language, and perform a station reset.
Troubleshooting information is available on the product page at
www.jbctools.com.

To update the station software, users need to download the JBC
Update File from www.jbctools.com/software.html and insert a USB
flash drive with the downloaded file into the station.

The product also includes an adjustable stand (sold separately)
that allows users to adjust the tool holder angle for comfortable
work position. The tool starts/stops blowing when lifted/returned
to the stand. The stand is designed for easy cartridge change
without switching off the station.

Product Usage Instructions:

1. Changing Cartridges:
2. Removing:

  * Place the cartridge in the extractor and pull the handle to  

remove it. Use the ring (J325) or umbrella (J125) around the
cartridge as a stop to extract it from the tool.

2. Inserting:
  * Place the handpiece on top of the new cartridge and press down  

slightly.

3. Fixing:
  * Use the holes to fix the cartridge at the right depth. The  

extractor holes also allow correcting the nozzle angle of curved
cartridges. To do this, rotate the tool with the cartridge inserted
in the extractor until the nozzle is in the right position.

Recommended
For rework jobs the use of the preheaters is highly recommended. Find the preheater that best suits your soldering needs in www.jbctools.com.
Applying high temperatures (350 ºC – 450 ºC / 660 ºF – 840º F) with a hot air tool for a long time can damage both, the printed circuit and the electronic components. In addition, significant temperature differences between two points on a printed circuit board can damage the printed circuit and the electronic components due to the stresses generated by the different expansion of the material. Preheating is a process that minimizes thermal stress and allows the soldering process to take no longer than it should. For most rework processes JBC recommends a preheat temperature between 90 and 130 ºC / 195 and 265 ºF and not exceed a heating rate of 4 ºC/s. With the use of JBC preheaters, a homogeneous and controlled heating is achieved within the recommended parameters.

Maintenance

Before carrying out maintenance, always switch the station off and disconnect it from the mains. Allow the equipment to cool down.

Clean periodically

– Clean the station screen with a glass cleaner or a damp cloth.

– Use a damp cloth to clean the casing and the tool. Alcohol can only be used to clean the metal parts.

– Periodically check that the metal parts of the tool and stand are clean so that the station can detect the tool status.

– Periodically check all cables and tubes.

– Replace a blown fuse as follows:

1. Pull off the fuse holder and remove the fuse. If necessary use a tool to lever it off.

2. Insert the new fuse into the fuse holder and return it to the station.

Fuse

– Replace any defective or damaged pieces. Use original JBC spare parts only. – Repairs should only be performed by a JBC authorized technical service.

Safety
It is imperative to follow safety guidelines to prevent electric shock, injury, fire or explosion. – Do not use the units for any purpose other than soldering or rework. Incorrect use may cause fire. – The power cord must be plugged into approved bases. Make sure that it is properly grounded before use. When unplugging it, hold the plug, not the wire. – Do not work on electrically live parts. – The tool should be placed in the stand when not in use to turn off the hot air. – The soldering tip, the metal part of the tool and the stand may still be hot even when the station is turned off. Handle with care, including during the stand position adjustment. – Do not leave the appliance unattended when it is on. – Do not cover the ventilation grills. Heat can cause inflamable products to ignite. – Avoid the contact of flux with skin or eyes to prevent irritation – Be careful with the fumes produced when soldering. – Keep your workplace clean and tidy. Wear appropriate protection glasses and gloves when working to avoid personal harm. – Utmost care must be taken with liquid tin waste which can cause burns. – This appliance can be used by children over the age of eight and also persons with reduced physical, sensory or mental capabilities or lack of experience provided that they have been given adequate supervision or instruction concerning use of the appliance and understand the hazards involved. Children must not play with the appliance. – Maintenance must not be carried out by children unless supervised.
