disassembly and assembly 

The argon gas is impure 

Replace with qualified argon gas 

The gas flow is too large or small 

Adjust the gas flow properly 

Arc is started 
between the 
electrode holder 
and tungsten 
electrode or 
welding torch 

The collet and tungsten electrode 
have poor contact, or arc is 
started when the tungsten 
electrode contacts the base metal 

Replace the collect or repair 

The collet and welding torch have 
poor contact 

Connect the collect and welding torch 
properly 

 

9. Troubleshooting   

Warning! Before arc welding machines are dispatched from the factory, they 
have already been checked thoroughly. The machine should not be tampered 
with or altered. Maintenance must be carried out carefully. If any wire 
becomes loose or is misplaced, it may be potentially dangerous to user! Only 
professional maintenance personnel should repair the machine!   
Ensure the power is disconnected before working on the machine. Always 
wait 5 minutes after power switch off before removing the panels.   

 

9.1. Common malfunction analysis and solution   

The symptoms listed here may be related to the accessories, gas, 
environmental factors, and power supply you use. Please try to improve the 
environment and avoid such situations.

   

  

Elimination of general problems in MMA   

Symptom 

Reasons 

Troubleshooting 

After startup, the fan does 
not turn or the wire feeding 
speed is abnormal 

The air temperature 
may be too low or 
the fan may be 
damaged 

When the temperature is too low, leave the 
machine work for a while. The temperature 
in standby will rise, then fan will resume 
normal operation. If it is still not working, it is 
necessary to replace the fan. 

MMA 

Hard to start the 
arc 

Arc hot start current 
is low 
Or the hot start time 
is short   

Increase arc start current or arc start time   

Unstable arc or 
excessive molten 
pool during arc 
start   

Arc start current is 
high 
Or the arc start time 
is long 

Reduce arc start current or start time 
appropriately 

Cannot start 

The power cord is 
not connected 

Connect the power cord
