Welding power supplies primarily serve as devices that allow a welder to exercise control over whether current is alternating current (AC) or direct current (DC), as well as the amount of current and voltage. Power supplies for welding processes that use shielding gas also offer connections for gas and methods to control gas flow.
Capacitive discharge power supplies store electrical energy and rapidly discharge it through a pulse transformer, producing a flow of electrical current through the welding head and workpieces. This stored energy is independent of line voltage fluctuations. Capacitive discharge power supplies are rated in accordance with the amount of energy they store and the welding speed.
A stored energy welding power supply, also known as a Capacitive Discharge Welder (CD Welder), extracts energy from the power line over a period of time and stores it in welding capacitors. This type of power supply thus provides an effective weld energy that is independent of line voltage fluctuations.
For simplicity, the capacity can be selected based on the required welding current by referring to the number behind the arc welding power supply model. For example, the number “300” in BXl-300 represents the rated current of the power supply is 300A. (2) Allowable welding current under different load duration rates
Likewise, spot welders require a different type of welding power supply, typically containing elaborate timing circuits and large capacitor banks that are not commonly found with any other types of welding power supplies. ^ Larry Jeffus (27 January 2011).
Capacitor Discharge (CD) power supplies store energy in a capacitor bank prior to the weld. The energy is discharged through a pulse transformer to the weld head. The resulting high peak current and very fast rise time is useful for welding very conductive parts.
