Question

Constant potential power sources with the slope control are used for which type of mode of transfer?

a) Globular transfer.
b) Spray transfer.
c) Pulsed current transfer.
d) Short circuit transfer.
e) Axial spray transfer.

Answer 1

Constant potential power sources with slope control are used for spray transfer in welding, where they enable consistent and steady droplet transfer.

Step-by-step explanation:

Constant potential power sources with slope control are typically used for spray transfer mode of metal transfer in welding processes. This type of power source allows for greater control over the welding arc, ensuring a steady, consistent transfer of molten metal droplets from the welding electrode to the workpiece. In spray transfer, the molten metal droplets are uniformly and finely dispersed, thanks to the steady voltage and current properties that constant potential power sources with slope control can provide.
