i have some questions about tig welder control circuits, hope some one can help.
in a tig welder you set a maximum amperage for the output then use the foot pedal to control the amperage within that range. how does the circuit work or what is the name for that type of circuit?
can anyone please point me to a circuit or explain how to build a circuit to do this?
thank you, cary
