To make a basic stick welder you need more than just a transformer and two windings sets. First off your open circuit voltage is way too low to be of any use. Typically a stick welder has a open circuit voltages of around 60 - 80 volts AC that pulls down to around 20 - 30 volts when an arc is struck.

WebThe radiation emitted by cell phones and microwave ovens overlaps two ranges. They’re the radio and microwave ranges at the lower end of the spectrum. As you might know, cell phones generally operate at 800MHz to 1900MHz. Microwave ovens use the 2.45GHz frequency. The following video explains the electromagnetic spectrum in more detail: WebMicrowave welding uses high frequency electromagnetic radiation to heat a susceptor material located at the joint interface; the generated heat melts thermoplastic materials at the joint interface, producing a weld upon cooling. Microwave welding is a type of electromagnetic welding, in addition to induction welding and radio-frequency welding ...
