4. SELECTING HEATER TIPS
OK International’s Heater Tips come in a wide variety of tip geometries and temperature ranges
(contact your local OK International Representative or visit our website for more information).
These tip geometries cover a broad range of tasks from delicate precision work to heavy ground
plane soldering.
1. Pick a tip that maximizes contact area between the tip and solder joint. Maximizing contact
area gives the most efficient heat transfer, producing high quality solder joints quickly.
2. Pick a tip that allows good access to the solder joint. Shorter tip lengths allow more precise
control. Longer or angled tips may be needed for soldering densely populated boards.
3. Pick the lowest temperature tip cartridge that will accomplish the task. This minimizes the
potential for thermal damage. The temperature series is marked on the shaft of the Heater
Tip.
5. REPLACING HEATER TIPS
1. Push the Power Switch “Off.” Removal of the
Heater Tip with the power On will result in damage
to the coil assembly.
2.
Pull out the heater tip using the supplied AC-CP2
Cartridge Removal Pad. DO NOT USE METAL
TOOLS (SUCH AS PLIERS) TO REMOVE
HEATER TIPS, AS THIS CAN DAMAGE THE
HEATER.
CAUTION: THE HEATER TIP MAY BE HOT!
1. Push a new heater tip into the solder handle with the supplied AC-CP2 Cartridge Pad.
2. Push the Power Switch “On.” The new heater tip will heat up to temperature in less
than 20 seconds.

6. REPLACING COIL ASSEMBLIES
1. Push the Power Switch “Off.” Wait for the heater tip to reach room temperature.
2. Remove the heater tip from the handle assembly. DO NOT USE METAL TOOLS (SUCH
AS PLIERS) TO REMOVE HEATER TIPS.
3. To disconnect the Coil Assembly from the Soldering Handle depress the button on the Coil
Assembly and pull it away from the Soldering Handle assembly.
4.
Insert the new Coil assembly into the handle assembly, you will feel a ‘click’ as it seats.
7. TROUBLESHOOTING
a. Power LED Not ON
• Check the power cord
• Check to see that you have mains voltage
• Check to see if the power switch is in the ON position
b. Tip Does Not Heat
• Is the LED Illuminated?
• Is the Hand-Piece Connected to the Power Supply?
• Is the PS-CA3 Coil assembly firmly inserted into the PS-H3 Soldering
Handle assembly?
• Is the Tip Firmly Inserted onto the PS-CA3 Coil Assembly?
• Has a replacement PS-CA3 been tried?
If you cannot resolve the problem after conformation of the above, please contact your local OK
International representative.
