LED Display

There is a luminous indication (LED) to the left of the display:

Green

The power unit is ready for welding.

Red

The power unit is locked

 

– after welding, until there is electrical contact with the work-

piece

 

– if the power unit is overheated (the display shows 8 .. 2). 

After a short cooling period, the work can continue.

Green

lights if the solenoid of the welding gun is controlled

Green

lights if the welding gun button is triggered

Yellow

lights if there is electrical contact between welding element 

and workpiece
