FAULT DIAGNOSTICS 

 

1. 

Power light not lit

 

Check machine on/off switch is in the ‘on’ position 
Check Input power to machine 
Check plug wiring 
Check mains trip / fuses

 

2. 

No output  - Fan runs - Power light is lit  

Check torch connections are secure and torch switch operation, try replacing plasma cutting 
torch

 

3. 

No output - Power light is lit - Warning light is lit 

Welding application may have exceeded recommended duty cycle, allow machine to cool down 
until the warning light goes out.

 

4. 

No output – Power light is lit – Air at torch tip – No cutting 
 

Check condition of torch consumables and replace if worn 
 
Check for water in water trap at rear of machine, if water is present, drain air compressor, clean 
water out of air lines, empty water trap by pressing water release button on bottom of air 
regulator water trap. Fit new consumables as per instructions earlier in this manual 
 
HF PCB Failure – Contact R-Tech for repair

 

5. 

Machine keeps overheating - Warning light is lit on machine 

Check if fan is running – if not contact R-Tech for repair 
Check the cooling vents for obstruction, blow out machine with clean dry low pressure air 
supply. Check for adequate ventilation around machine

 

6. 

Erratic cut – Torch spitting when cutting 

Check torch consumables and replace if necessary as per instructions earlier in this manual

 

 

Check if correct amperage for thickness of metal, if travel speed is too fast or to not enough
