Arc Welding Equipment
Electricity in welding machines:
In welding, the relationship between voltage (the pressure) and amperage (the amount of electricity
flowing), is most important. In arc welding, there are two voltages to be considered: (1) open circuit
voltage (OCV) and (2) arc voltage (AV). OCV is the voltage that exists between the terminals of the
welding machine when there is no welding being performed. It is approximately 70V to 80V. AV is
the voltage between the electrode and the base metal during the actual welding operation (15V to
40V).
“CC” means: constant current. These were the first welding machines. They are still used for
SMAW and GTAW because a steady current (amperage) is very important in these processes.
Another machine with constant voltage is called constant voltage or constant potential (CV or CP)
machine, which has a constant much lower OCV. With GMAW, constant voltage is essential.

ReplyDeleteAlthough many people believe that there is only one basic welding application, there are actually many different applications involved with welding. One of these areas best welder under 1000 is the stud welding process, where a bolt or formed nut is welded onto another metal piece.
