  2. Welding power supply - Wikipedia

    en.wikipedia.org/wiki/Welding_power_supply

    A transformer-style welding power supply converts the moderate voltage and moderate current electricity from the utility mains (typically 230 or 115 VAC) into a high current and low voltage supply, typically between 17 and 45 (open-circuit) volts and 55 to 590 amperes.

  3. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    Most single phase alternating-current electrical outlets in the world supply power at 210–240 V or at 100–120 V. A transformer or autotransformer can be used; (auto)transformers are inherently reversible, so the same transformer can be used to step the voltage up, or step it down by the same ratio. Lighter and smaller devices can be made ...
