An example of ACM's speciality range, the dockyard weld tester supplies a measured current to an electrode separated from a weld by sensitised paper.
A portable instrument with internal battery and built-in recharger ideal for use in the confines of a nuclear submarine. The desired current is set using a dialled knob between 1 mA and 1000 mA in 1 mA steps. The instrument automatically adjusts the output voltage up to 10 volts in order to supply the current.
It is also possible to set the pulse time from 1 to 60 seconds in 1 second intervals using two rotary switches. A small light indicates battery condition. After the current is passed through the impregnated paper the state of the weld is diagnosed from the resulting colour change.
