VOLTAGE SENSING
The best arc performance occurs when the Power Wave has accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influence the volt- age apparent at the terminals of the welder. Voltage sense leads improve the accuracy of the arc conditions and can have a dramatic effect on performance.
CAUTION
If the voltage sensing is enabled but the sense leads are missing or improperly connected, extremely high welding outputs may occur.
Do not tightly bundle the work sense lead to the work lead.
The sense leads connect to the Power Wave at the
Enable the voltage sense leads as follows:
