This Standard specifies a welding current meter with a current sensing coil to measure the weld time and the effective value of the welding current during a certain interval in single phase ac of frequency of 50 Hz or 60 Hz, or dc.This standard is applicable for a welding current measuring system with a display or output port calibrated, which may be connected into a welding controller. When the welding current meter is used for measuring pulsed currents as capacitor discharge current, an agreement concerning additional specifications may be needed between the manufacturer and the purchaser.
