5. On/Off 

Power 

Switch 

 
This turns the I-Mig200 Mig Welder on and off. 
 

6. Wire 

Speed 

 

This adjusts the wire feed speed from 0-100% 
 
Adjust the wire speed to suit welding voltage (Fig 3.1) and job requirements 
 
When adjusting the wire feed speed a value is shown in the amperage LED (Fig 3.8) 
 
This feature allows you to record this value along with the preset welding voltage for easy 
setup to specific job when several different welding jobs are being done 
 

7. Voltage 

LED 

Display 

 

This shows the preset welding voltage when no welding is being carried out 
 
When welding this shows the actual welding voltage 
 
This allows the machine to be calibrated to BS if required by your company

 

 

8. Amperage 

LED 

Display 

 

This shows the preset wire feed speed when no welding is being carried out 
 
When welding this shows the actual welding amperage 
 
This allows the machine to be calibrated to BS if required by your company 
 
 

9. Warning 

LED 

 

This warning light will come on under these situations

 

 

Duty cycle of machine has been exceeded, the machine will stop working and the fan will 
continue to run until machine has cooled down. The light will go off and welding may be 
carried out again. 
 
If duty cycle has not been exceeded the warning light comes on to warn of either 
low input voltage has been sensed or there is an internal fault with machine 
 

10. Power LED 

 
This lights when machine is switched on
