TIP USE AND CARE
• Tip Temperature: High soldering tempera-
tures can degrade the tip. Use the lowest
possible soldering temperature. The excel-
lent thermal recovery characteristics ensure
efficient and effective soldering even at low
temperatures. This also protects the soldered
items from thermal damage
• Cleaning: Clean the tip regularly with a clean-
ing sponge,as oxides and carbides from the
solder and flux can form impurities on the tip.
These impurities can result in defective joints
or reduce the tip's heat conductivity. When us-
ing the soldering iron continuously, be sure to
loosen the tip and remove all oxides at least
once a week. This helps prevent seizure and
reduction of the tip temperature.
• When Not in Use: Never leave the solder-
ing iron sitting at high temperature for long
periods of time, as the tip's solder plating will
become covered with oxide,which can greatly
reduce the tip's heat conductivity.
• After Use: Wipe the tip clean and coat the tip
with fresh solder. This helps prevent tip oxida-
tion.

MAINTENANCE

WARNING: Inspect and clean the tip. Never
file the tip to remove oxide.
1. Set the temperature to 250° C.
2. When the temperature stabilizes,clean the
tip wit)! the cleaning sponge and check the
condition of the tip.
3. If there is black oxide on the sloder - plated
portion of the tip, apply new solder (contain-
ing flux) and wipe the tip on the cleaning
sponge. Repeat until the oxide is completely
removed. Coat with new solder.
4. If the tip is deformed or heavily eroded, re-
place it with a new one.
CHECKING FOR BREAKAGE OF THE HEAT-
ING ELEMENT AND CORD ASSEMBLY
Disconnect the plug and measure the resis-
tance value between the connecting plug pins
as follows:
If the values of 'a' and 'b' are outside the above
value, replace the heating element (sensor)
and / or cord assembly.
14
If the value of 'c' is over the above value, re-
move the oxidization film by lightly rubbing
with sand paper or steel wool.
a. Between pins 4 & 5 (heating element): 2.5 -
4.0 Ω (Normal).
b. Between pins 1 & 2 (sensor): 43-58 Ω (Nor-
mal).
c. Between pins 3 and tip: Under 2 Ω
BROKEN HEATING ELEMENT
1. Turn the nut (1) counterclockwise and re-
move the tip enclosure (2), the tip (3).
2. Turn the nipple (4) counterclockwise and
remove it from the iron.
3. Pull both the heating element (6) and the
cord assembly (11) out of the handle (12). (To-
ward the tip of the iron).
4. Pull the grounding spring (5) out of the D-
sleeve.
- MEASURE WHEN THE HEATING ELEMENT IS
AT ROOM TEMPERATURE
1. Resistance value of heating element (RED)
13-16 Ω
2. Resistance value of sensor (BLUE) <2 Ω
If the resistance value is not normal, replace
the heating element (Refer to the instructions
included with the replacement part.)
- AFTER REPLACING THE ELEMENT
1.. Measure the resistance value betwee;
a) Pin 4 y 1 or 2.
b) Pin 5 y 1 or 2. If it's not ∞, the heating ele-
ment and sensor are touching. This will dam-
age the PWB.
