Performance analysis of a low-power-consumption electric arc welding machine constructed using cost effective materials [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2023
Electric arc welding is a widely used fusion welding method. Electric power is supplied to the primary winding of the transformer as the input, and due to induction, it is transferred to the secondary winding from which it will be utilized for welding.
