WeldingMeter

###A welding meter/scope with voice output. This is perfect for TIG welding with a foot pedal. The actual current is read with voice output. For welding with pulse function the pulse frequency, duty cycle, minimum and maximum values and also the current curve is displayed. After the current reaches a value below 5A, the scope is automatically stopped and there is a history memory, so it's possible to go scroll back the last 60 seconds.

Voice output in german and danish language. Measurement range -300A to +300A.
