Symbol and Function explanations
MMA welding
MMA welding may also be referred to as welding with coated electrodes. Striking the
arc melts the electrode, and its coating forms protective slag.
Active panel
Settings are made from the control panel.
Remote control unit
Settings are made from the remote control unit.
The remote control unit must be connected to the remote control unit socket on the
machine before activation. When the remote control unit is activated the panel is
inactive.
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.
If the VRD function is activated and the open-circuit voltage exceeds the 35 V limit,
this is indicated by an error message (16) appearing in the display and welding
cannot be started whilst the error message is displayed.
Contact an authorised ESAB service technician to activate the function.
