Abstract
The arc-welding monitor has a weld power supply, units for generating signals proportional to welding current and voltage, an audio-signal generator, welding current and voltage comparators and a monitoring sequence logic analyzer having a signal switch responsive to variations of monitored quantities, which is connected to the outputs of said welding current and voltage comparators, a signal switch responsive to incremental changes in monitored parameters, and welding current and voltage adders. One input of each adder is connected to the outputs of said units for generating signals proportional to welding current and voltage, respectively, while the second input of each adder is combined with the input of the corresponding comparator, the outputs thereof being connected to the inputs of the signal switch responsive to incremental changes in monitored parameters.
