鈥?Current-limiting devices designed specially for use on welder
circuits only.
鈥?Time-current characteristics are designed to hold on the inter-
mittent overloading encountered in welder operation, while pro-
viding short-circuit protection to the circuit and equipment.
鈥?Welder limiters have excess current capacity in the operating
range as needed for this type of service.
鈥?Because of the special characteristics of the welder limiters,
they are not intended for application on general-use circuits.
