POWER DESOLDERING METHOD

The recommended desoldering technique for P.C. boards is to heat the soldered connection with the component lead end

inside the tiplet until the solder is visually melted. This should take 1 to 5 seconds depending on the particular connection

being desoldered. The tiplet surface should be held flush with the P.C. board pad during heating and desoldering. Addition of

a small amount of flux core solder will sometimes improve this process. As the solder melts, the tiplet should be moved with

a circular motion.

This movement will cause the component lead to move around in the P.C. board hole. Depress the push button and hold it

depressed while continuing to rotate the tiplet for 1 - 2 seconds. Remove the tiplet from the pad and then release the push

button, The movement of the lead in the hole and subsequent cooling of pad and lead to below solder melt temperature will

prevent the remaining solder on the pad and lead surfaces from solidifying together. This technique is definitely required when

desoldering plated through holes on double or multi-layer P.C. boards.

USING DESOLDERING HEAD FOR HOT AIR HEATING

WARNING: BE SURE TO REMOVE ALL THE SOLDER FROM THE TIPLET, GLASS TUBE, AND CONNECTOR

TUBE BEFORE USING THE TOOL FOR HOT AIR APPLICATIONS. NEVER DIRECT HOT AIR

TOWARD ANY PART OF YOUR BODY OF OTHER PEOPLE.

It is recommended that a separate desoldering head be used for hot air applications to eliminate the need for thorough

cleaning before using, however, the following procedure will insure that no solder is left in the tool.

PROCEDURE FOR CONNECTING THE TOOL FOR HOT AIR USE:

1. Turn the unit on and allow it to heat (3 minutes minimum).

2. With tube connected to vacuum, hold the tool vertical with the tiplet up and actuate the vacuum source ten

seconds.

3. Insert a tip cleaning tool in the tiplet and force it through into the solder collection chamber with vacuum present.

4. Hold the tool vertical and operate the push button for 5 seconds, then switch the unit off and continue to hold the

tool vertical until the tiplet cools at least below solder melting temperature.

5. Remove tiplet and clean end. Remove the glass tube and clean all solder from it. Check delivery tube and remove

solder. Remove the cotton filter. Replace glass tube. Make sure the gaskets are properly seated. Tighten sealing

nut finger tight. Replace tiplet.

6. Connect the rubber tube connected to the vacuum fitting to the air fitting.

7. Turn the unit on and wait 3 minutes for heat up.
