Gas flow can be measured as follows:
- In-line Gas flow meter (max. pressure 25 Psi)
Every second a set of measurements is displayed on a small LCD monitor. When the arc voltage and arc current do so indicate, the measurement sets are stored on the logger’s harddisk. The measurements are grouped into layers, which have to be named by the operator; each layer is automatically divided into runs, each corresponding with the moment that the actual welding started. When a standard line printer is connected, then for every run a print-out is produced, with a line of data every second. While the VT logger is logging new data, older data can be reviewed as well.
