Arc welder ,,,, ARC Welder Inverter MMA 240V 160amp DC Portable Stick Machine ....a quarter the price of the item in post above , and you get a mask and some thick wires
The problem with a SMAW (stick welder) the open circuit voltage is high, <100v it collapses drastically to around 20-30v when an arc is struck.
The transformer has a shunt that is cranked in to control the level.
The initial high voltage is in order to start the arc.
