necessary of equipment
 

When the just of turn on the power of alternating arc welding machine, there is about from 65 voltage to 90 voltage and from 8A to 15A of electric current at second holder and earth of welding machine. This is very dangerous for the worker. The removement can make to save the workder and save the money of electri cost.
