SMAW Welding Power Source

Stick MMA or SMAW Welding Power Source

MMA stands for Manual Metal Arc Welding. It is also known as SMAW or  Shielded Metal Arc Welding. The power source required for this process should be capable of giving a constant current even if the arc voltage changes due to small changes in arc length. The current used to weld may be AC or DC.This characteristic can be incorporated using any of the five technologies given below. Each of these power sources have their own advantages and disadvantages.
