The operation of the timer can be modified by modulating the internal threshold and trigger voltages, which is accomplished by applying an external voltage (or current) to CONT.
During the arc time, changing rate of current could be adjusted by modulating the parameter of the control circuit, which ensures the proper output power of the arc.
