Ammeter

Indicates  the welding  current. 

2

Power  Lamp

It indicates that the machine is on and input voltage is within acceptable 

range.

3

Current  Lamp

It indicates the machine is ready to adjust welding current. 

4

Warning Lamp

It  indicates  the  thermal  over  load  or  output  disabled  by  any  electrical 

problems or the failure of program. When it is on, the machine will not 

supply power at the output.

5

Power  Switch
