VRD (Voltage Reducing Device)
The VRD function ensures that the open-circuit voltage does not exceed 35 V when
welding is not being carried out. This is indicated by a lit VRD LED.
The VRD function is blocked when the system senses that welding has started.
Contact an authorized ESAB service technician to activate the function.
Overheating protection
The welding power source has overheating protection that operates if the
temperature becomes too high. When this occurs the welding current is interrupted
and a overheating indication lamp is lit.
The overheating protection resets automatically when the temperature has fallen,
within normal working temperature.
Arc force
The arc force is important in determining how the current changes in response to a
change in the arc length. A lower value gives a calmer arc with less spatter.
This only applies to SMAW welding.
Inductance
Higher inductance results in a wider weld pool and less spatter. Lower inductance
produces a harsher sound but a stable, concentrated arc.
This only applies to GMAW welding.
