AMV3000
AMV3000
The AMV3000 is a great tool for general manual fabrication workshops.
Each unit is supplied with:
• Voltage leads
• Current clamp
• Printer mounting plate
The AMV3000 unit is capable of monitoring voltage, current and wire feed speed or temperature (option).
Arc Current
Monitored using a Hall Effect probe, it’s 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.
Temperature
Monitored using a k series thermocouple. This is an option and can replace the wire feed channel.
Calculated values
• Average welding parameters (I,V,WFS)
• Heat input (no process efficiencies)
