RECOMMENDED SETTINGS 

 
 
Firstly, it must be stressed that a good weld can only be made onto a 

GOOD

 section of track 

or pad. 
 
Copper thickness, width, quality, cleanliness, coatings (ie tin-lead), will all affect the settings 
and adjustments will have to be made if a perfect weld is to be achieved. 
 
Therefore, the settings shown below are 

ONLY GUIDELINES

 and should be thought of as 

a 

STARTING POINT ONLY

.  Trial and error will determine the actual settings you require 

for your job.  All settings are based on 1oz (35 micron) copper tracks. 
 

Good quality, clean copper track  
Electrode Gap 0.008” (0.20mm) 

Threshold 70 (default)

REMEMBER! 
 
IF THE AMPS SETTING IS 

too low

 OR 

too high

, THE 

CIR-KIT WELD 450

 

WILL TRY TO WELD, BUT WILL REDUCE THE OUTPUT TO PROTECT 
THE TRACK FROM FURTHER DAMAGE.  THIS IS SUBJECT TO THE 
CORRECT ELECTRODE GAP SETTING.
