  2. Welding power supply - Wikipedia

    en.wikipedia.org/wiki/Welding_power_supply

    A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).

  3. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used.

  4. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    24, 36, and 48 V DC, which are common standards for home energy systems. 200 to 400 V DC, when power is from photovoltaic solar panels. 300 to 450 V DC, when power is from electric vehicle battery packs in vehicle-to-grid systems. Hundreds of thousands of volts, where the inverter is part of a high-voltage direct current power transmission system.

  5. Induction welding - Wikipedia

    en.wikipedia.org/wiki/Induction_welding

    The apparatus used for induction welding processes includes a radio frequency power generator, a heating station, the work piece material, and a cooling system. The power generator comes in either the form of solid state or vacuum tube and is used to provide an alternating current of 230-340 V or a frequency of 50–60 Hz to the system.

  6. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    Consumer electronics usually include an AC adapter (a type of power supply) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips. Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power.

    NEW YORK (Reuters) - This winter is forecast to bring sudden bouts of extreme cold to Texas that could test the state's electric grid in early 2025, the grid operator's chief meteorologist said on ...

  8. Shielded metal arc welding - Wikipedia

    en.wikipedia.org/wiki/Shielded_metal_arc_welding

    Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
