2. Remove the soldering tip and metal soldering tip retaining collar
using the above procedure. Unscrew the Black "Bakelite Polymer"
Retaining Cap and slide off this secondary heating element retaining
collar.
3. Push the Power Cord through the bottom of the soldering iron while
(at the same time) gently pulling the heating element out of the top of
the iron.
4. De-solder the 2 Red and 2 Blue wires that have heat shielding on
them from the circuit board and pull the heating element away from
the mother board. Please take note of the wire colors and location
for installation of new heating element.
5. Install new heating element and solder Red & Blue Wires to the new
heating element.
6. Pull the cord back gently and align the PC board to the slot so the
cord can be pulled back to its original position.
7. Replace Bakelite Polymer Retaining Cap and screw back on and
hand tighten.
8. Install the soldering tip, slide the metal soldering tip retaining collar
and hand tighten it. Plug the AC cord back into a grounded Outlet.
NOTE: The wires on the heating element can be soldered back onto the
board on either solder pad as there is no polarity for the element.
SOLDERING TIPS PREPARATION & CARE
1. Keep the soldering tip properly tinned. Always use solder with
sufficient rosin flux or the tip will de-wet. A well tinned tip will be bright
all over when hot, with no dull or discolored spots.
2. To tin the iron, do the following:
a. Plug in the iron and allow it to reach solder melt temperature.
b. Flood the tip with solder and let it stand for one minute.
c. Apply more solder to the tip, allow it to idle for one or two more
minutes, wipe it lightly on the sponge. Do not remove all of the
solder, but use the sponge to remove excess solder and wipe
solder onto non-tinned areas.
3. Do not file or attempt to reshape the tip. This will destroy the plating
and shorten tip life. Do not use chloride and acid fluxes; they will also
shorten tip and heater life.
4. For maximum tip life, always apply solder to the heated connections
or joints. Repeated application of solder directly to the tip will
shorten the tip life.
WARNING: Do NOT use anti-seize or any other lubricant on the tip
retainer or heater of the soldering iron.
