OPERATING INSTRUCTIONS – PART 2 

 
Here are some Questions and Answers that may be of help to you in understanding the  
CIR-KIT WELD 450 
 

WHAT IS THE CIR-KIT WELD 450? 

It is a constant current, microprocessor controlled, parallel gap welder with additional 
repair tools. 

 

WHAT CAN THE CIR-KIT WELD 450 BE USED FOR? 

For the repair of open circuits (o/c) or reduced width tracks on printed circuit boards 
(PCB’s), and for welding fine wires, such as solenoid or motor leads to terminals. 

 

HOW DO I REPAIR A PCB? 

Simple!  Detect the o/c by visual inspection or electrical testing.  Place the pcb on the 

CIR-KIT WELD 450

 base with the o/c track under and slightly to the right of the weld 

head electrodes.  Select a repair ribbon of suitable width from the choice of three 
supplied, and with the hand tool supporting it, lay it on top of the damaged track.  
Select a power/time setting and bring the electrodes down and into contact with the 
ribbon, by operating the foot pedal switch.  The weld is automatically made.  Move 
the pcb and ribbon along, thereby, bridging the o/c with the ribbon.   Repeat the weld 
procedure.  Cut off excess ribbon with the scalpel provided.  Job complete. 

 

WHAT FURTHER MANUFACTURING PROCESS WILL THE REPAIRED TRACK 
NOW WITHSTAND? 

Just about any process, as the repair is a weld and not a soldering operation.  Electro-
plate, tin/lead and reflow it.  Hot Air Level it.  Even Roller Tin it and of course, a 
Solder Mask can be applied over it. 

 

WHAT ADJUSTMENTS DO I REGULARLY NEED TO MAKE TO THE CIR-KIT 
WELD 450? 

Very few: 

 

 

Select thickness of PCB on weld head 

 

Switch to preset power setting or manual adjust. 

 

Adjust electrode gap for different ribbon widths. 

 

DO I NEED TO WAIT FOR THE CIR-KIT WELD 450 POWER PACKS TO 
CHARGE BEFORE USING EACH TIME? 

No.  After its initial charge (1 hours), it is always ready to use. 

 

(PLEASE NOTE:  If the machine is not in continual use, it should be periodically, ie 
weekly, switched on for a minimum of 2 hours to re-charge).
