BASIC TROUBLESHOOTING GUIDE 

PROBLEM 3: SOLDERING IRON TEMPERATURE IS INTERMITTENT 
Description: 

Main power LED lights up and so does the heater LED but 

soldering iron temperature rises and falls uncontrollably.

 

 
SOLUTION:  

◆ 

 

Soldering iron plug may be loose from the receptacle unplug the 

 

soldering iron and reattach. 

◆ 

  Soldering iron cord may be damaged or loose and needs to be 

 

replaced or repaired. See trouble shooting soldering iron cords 

 

section of this manual. 

 
PROBLEM 4: SOLDER WOULD NOT STICK TO THE SOLDERING TIP 
Description: 

Soldering iron is able to quickly melt solder but cannot cause the 

solder to attach to the tip.

 

 
SOLUTION:  

◆ 

  Soldering iron tip may already be too dirty or oxidized . Please see 

 

our solder tip maintenance guide on how to clean soldering tips. 

◆ 

  Temperature could be set too high causing solder to quickly burn 

 

away, Please adjust to a more suitable lower temperature range. 

 
PROBLEM 5: SOLDERING IRON DOES NOT PRODUCE ENOUGH HEAT 
Description: 

Soldering iron cannot melt solder fast enough, or actual 

temperature does not reach the desired set temperature. 

 
SOLUTION:  

◆ 

 

The system may need to be recalibrated please  

◆ 

  Soldering iron tip may already be too dirty or oxidized . Please see 

 

our solder tip maintenance guide on how to clean soldering tips.
