Welding Power Diagram. Welding torch see diagram 2 4. Power source tig welding can be carried out using dc for stainless steel mild steel copper titanium nickel alloys etc and ac for aluminium and its alloys and magnesium.
35khz ultrasonic welding generator circuit diagram separate excitation. Gas tungsten arc gas welding gtawtig this type is the most common method used for welding together thick sections of stainless steel or non ferrous metals. The welding transformer of the integral reactor type shown in fig.
The welding circuit consists essentially of the following elements.
And do not work alone. The power source the purpose of the power source is to feed the electric arc which is. To the position in which welding is to be performed and to the size and kind of electrode used. The voltage v is determined by the electrode diameter and the distance between the electrode and work piece.
