Overheating protection

The welding power source has overheating protection that operates if the
internal temperature becomes too high. When this occurs, the welding
current is interrupted and an overheating symbol appears on the display.
The overheating protection resets automatically when the temperature has
returned to normal working temperature.

5.10

Voltage Reduction Device (VRD)

A VRD (Voltage Reduction Device) is a hazard reducing device designed to reduce electric
shock hazards present on the output of the welding power source when operating in MMAW
(stick) mode. Note that the presence of VRD should

not

be used as a substitute for the use

of appropriate safety practices as indicated in the "SAFETY" chapter of this manual!

Both the green and the red indicators on the power source control panel only operate in
MMAW (stick) mode. The green

VRD ON

light illuminates (red light is off) when the VRD is

active

. Under this condition the open circuit voltage of the unit is limited to below 35 V DC,

thus reducing the potential of serious electric shock (such as when changing electrodes).

The red

VRD OFF

light illuminates (green light is off) when the VRD is

inactive

. Under this

condition the output voltage of the unit will be at welding potential which in some cases may
exceed 35 V DC.
