The best penetration is achieved with dcen current. Mild steel is expensive and requires the most amount of cleaning. Copper-coated steel welding rods are not used for gas tungsten arc welding because they will continue the weld or electrode.
Answer:

Explanation:
Given that
Vrms= 60 V
Vf= 0.7 V
We know that peak value of AC voltage given as

Now by putting the values

The output voltage of the DC current given as



Therefore output voltage of the DC current is 84.15 V.
Answer:
Speedometer
It shows our speed, or how fast we're moving.
