Output Problems 

 
 

 

No output  - Power light is not lit 

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

 

 
 

 

No output  - Fan runs - Power light is lit  
 

Check torch connections are secure and torch switch operation, try replacing mig torch.

 

 
 

 

No output - Power light is lit - Warning light shows RED colour 
 

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

 

 

No output – Power light is lit – Warning light shows GREEN colour 
 

Output overload problem – Output diodes or IGBT faulty – Contact R-Tech 
 

 

 

No output – Power light is lit – Gas at torch tip – No wire feed 
 

Check wire feed unit protecting fuse on rear of machine, if blown 
replace with new fuse of same rating, If fuse flows again contact R-Tech

 

 
 

 

Machine keeps overheating - Warning light is lit RED 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

 

 

 

Porosity in weld – No / low gas at torch tip 
 

Check gas supply from gas bottle & check flow rate on regulator 
 
Check gas hose for restrictions 
 
Check for draughts in local area, open doors etc 
 
Replace mig torch – may have gas restriction

 

 

 

Poor weld penetration 
 

Check condition of earth lead and clamp and ensure clamp is connection via a clean area on 
work piece 
 
Check condition of mig torch, try other mig torch
