Each AMV 3000 comes with:
- Voltage leads
- Current clamp
- Printer mounting plate
- Temperature box and magnetic thermocouple OR AMV309WFT Wirefeed speed unit.
The AMV309WFT wirefeed speed unit is available in the following configurations:
The unit is capable of monitoring voltage, current and wire feed speed or temperature.
Monitored using a Hall Effect probe. It is possible to monitor both DC and AC current waveforms. The average value is calculated from the mean (rectified) value.
The arc voltage should be measured as close as possible to the arc. If this is not done the voltage drop across the welding leads will be recorded as well as that across the arc. However, it is standard practice to measure the arc voltage at the wire feed unit for MIG welding.
The wire feed speed is recorded as the average value. A tachometer is mounted directly on the wire.
The following values are automatically calculated and presented in the weld summary:
- Average welding parameters (I,V,WFS,T)
- Heat input (no process efficiencies)
