Product Description

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:

• 0.4-6m/min
• 0.8-12m/min
• 1.6-24m/min

The unit is capable of monitoring voltage, current and wire feed speed or temperature.

Arc Current

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.

Arc Voltage

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.

Wire Feed

The wire feed speed is recorded as the average value. A tachometer is mounted directly on the wire.
