AMV 3000

AMV 3000 is a microprocessor based instrument which has been designed to meet the quality standards for arc welding. The AMV 3000 is a robust unit with air-borne and line HF protection and is capable of monitoring both DC and AC welding parameters.

Welding parameters

The unit is capable of monitoring voltage, current and wire feed speed, although the wire feed tacho must be purchased separately.

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 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.

Calculated values
The following values are automatically calculated and presented in the weld summary:

• Average welding parameters (I,V,WFS)
• Heat input (no process efficiencies)
