One of the things that I'm always amazed at from an electrical perspective is the amount of current that is used in welding. Just as an example, let's assume a welding setup calls for 25V and we measured the resistance between the wire on the welding gun at .167 ohms. If we use the standard ohm's law formula where I = E/R we could solve for current. In the formula I = current, E=voltage, and R=resistance.



Solve for current (I) using the information provided.

To solve for current (I), we can use the formula I = E/R.

Given:
Voltage (E) = 25V
Resistance (R) = 0.167 ohms

Substituting the values into the formula:
I = 25V / 0.167 ohms

Calculating the current:
I = 149.7012 A

Therefore, the current is approximately 149.7012 Amperes.
