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.

Arc-welding monitor

An arc trainer for welders comprises a welding electrode simulator, a welding object simulating unit, a welding power source whose outputs are connected to the electrode simulator and to the welding object simulation unit, a unit controlling the quality of the simulated welding process and generation of feedback signals for the trainee, which is connected to the welding electrode simulator and to the welding power source, a unit monitoring variations of welding parameters, which is connected to the control unit and to the welding power source, and a helmet connected to the control unit.

Electric-arc trainer for welders

The welder's trainer comprises an welding electrode simulator, an electric-arc welding heat balance electronic model, a welding situation visual synthesis electronic model, a welding situation simulator made in the form of a television-type display, to which the welding situation visual synthesis electronic model is connected, and a training control and monitoring unit connected to the display through the visual synthesis electronic model.
