    The company manufactures and sells inverter welding machines, engine driven welders and other welder equipment primarily used in construction. [2] Jasic is listed on The Shenzhen Stock Exchange. [1] [2] Jasic was the center of a labor and political conflict in the city of Guangdong, referred to as the Jasic Incident. [4]

  3. 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).

  4. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

  5. Gas metal arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_metal_arc_welding

    Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).

  6. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]

  7. Flux-cored arc welding - Wikipedia

    en.wikipedia.org/wiki/Flux-cored_arc_welding

    Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant- voltage or, less commonly, a constant- current welding power supply .
