摘要： A consumable welding element for arc welding comprising a steel sheath surrounding a compacted core containing metal alloying powders and an essentially 100% basic compound in an amount less than about 1.60% of the total weight of said element. The basic compound is calcium fluoride powder which is preferably in the range of about 0.1% to about 0.9% calcium fluoride powder by total weight of the element. As another feature the core of the element contains a specific agent for decreasing the amount of diffusible hydrogen in the weld metal. This new element may be a filler metal for TIG welding; however, it is preferably a consumable electrode for MIG welding.

The improvement comprises a background current circuit means between the power supply and the work station and in parallel with the current control means and first means for applying continuously a background current across the work station. This background current circuit means includes a second means for creating a second inductive reactance substantially greater than the first inductive reactance and a resistor means for controlling the background current flowing continuously from the power supply to the work station through the background current circuit means.
