STEPS in Checking, Cleaning and Tinning the Tip 

1. 

Set temperature to 250

°

C (482

°

F) 

2. 

After  real  temperature  reaches  the  set  temperature,  use  a  damp 

sponge to clean the tip and check for damages. 

3. 

If  the  tip  has  oxidation,  apply  solder  and  wipe  using  the  damp 

sponge, repeat these steps until oxidation is removed. 

4. 

After  cleaning,  coat  tip  with  a  thin  layer  of  solder  and  set  it  aside 

ready for the next usage. 

5. 

If the tip shows disfiguration or has rust on it. Change the tip.

 

The  hand  piece  may  be  disassembled  for  trouble  shooting  and 

repair: 

1. 

Turn of main station and unplug from power source. 

2. 

Detach  the  soldering  iron  plug(”15”  as  shown  in  the  figure  below) 

from the main unit. 

3. 

Turn the nut, (“1” as shown in the figure below) counter clockwise. 

4. 

Pull out the tip enclosure (“2” as shown in the figure below),  the tip 

(“3” as shown in the figure below) , and the tip stand (“4” as shown 

in the figure below). 

5.
