Abstract :
THE COST OF APPARATUS for arc welding with the a-c. arc is less than that for the d-c. arc. In spite of this the d-c. arc has been used much more extensively because: the open circuit voltage of the a-c. welder was about double that of the d-c. equipment with a consequent increased life hazard; the a-c. arc was much more difficult to strike and hold; and it also drew a low power factor current from the line.
