Checking for Breakage of the Heating Element & Cord Assembly
Disconnect the Plug and measure the resistance value
between the connecting Plug Pins as follows.
(See Figure 15)

Between Pin 4 & 5 (Heating Element)
Between Pin 1 & 2 (Sensor)

If the values of ‘a’ and ‘b’ are outside the above value,
replace the Heating Element (sensor) and/or Cord
Assembly. If the value of ‘c’ is over the above value,
remove the oxidization film by lightly rubbing with fine
sand-paper or steel wool the points as shown in Figure 16.
1. Broken Heating Element
Measure when the Heating Element is at room
temperature (See Figure 17)
After replacing the Heating Element:
(Please see Figure 24 for details.)
1) Turn Nut (2) counterclockwise and remove the Tip
Enclosure(3), the Tip (4).
2) Turn Nipple (5) counterclockwise, remove it from the
lron.
3) Pull both the Heating Element (7),Terminal Board (8)
and the Cord Assembly (12) out of the Handle (9)
(toward the Tip of the lron).
1) Resistance value of Heating Element 2.5-3.5 W
2) Resistance value of Sensor 43-58 W. If the resistance
value is not normal, replace the Heating Element.
1) Measure the resistance value between
Pin 4 & 1 or 2
Pin 5 & 1 or 2
Disassembling the Iron unit
If it is not , the Heating Element and Sensor are
touching. This will result in damage of PWB.

Measure the resistance value a, b, and c to confirm
tha tthe leads are not twisted and that the Grounding
Spring is properly connected.

2. Broken Soldering lron Cord
There are two methods of testing the Soldering lron
Cord.
Turn the unit ON and set the Temperature Control Knob
to its maximum on the dial
(
). Then wiggle
and kink the lron Cord at various locations along its
length, including the strain relief area.(See Figure 18).
If the LED Heater Indicator flickers, the Cord needs to
be replaced.

CAUTION:
The LED Indicator will flicker even
with a normal lron Cord if the temperature reaches

!
Check the resistance value between the Pin of the
Plug and the Wire on the Terminal.

(Figure 18)
Pin 1: Black Pin 2: White
Pin 3: Green
Pin 4: Red
Pin 5: Blue
The value should be 0. If it is greater than 0 or is , the
Cord should be replaced.

Replacing Fuse
Turn loose the Fuse Cover counterclockwise and remove
the blown Fuse, change a new one with the same rated
Fuse. (See Figure 19). Check the Specifications on page
18 for Fuse rating.
