The circuit comprises a heating resistance 1 for the welder, connected to the mains 2 and a triac T between two capacitors C1, C2, that switches the supply of current to the heating resistance on and off. When the temperature rises, a potentiometer P levels the previous resistance, cancelling the flow of current in the triac T, until it goes down.
