Welding Power Sources For Semi-automatic Processes Flashcards
1
Q
What power source is used for GMAW and FCAW processes?
A
Direct current, constant voltage and DCEP
2
Q
What is inductance and what does it do?
A
Inductance is a circuit characteristic of most CV power sources. Its function us to lengthen the response time of the welding power source to change in the load.
3
Q
What is a disadvantage for CC machines?
A
It uses a variable speed drive motor and this means it has a harder time starting.
4
Q
