VRD: safety
principle
The welding circuit resistance is great-
er than the minimum human body res-
istance (greater than or equal to 200
Ohm):
-
VRD is active
-
Open circuit voltage is limited to
35 V
-
Unintentional contact with the
output voltage does not put the
welder at risk
The welding circuit resistance is less
than the minimum human body resist-
ance (less than 200 Ohm):
-
VRD is inactive
-
Output voltage not restricted in
order to ensure sufficient welding
power
-
Example: Welding starts
In MMA welding mode:
Within 0.3 seconds of end of welding:
-
VRD is active again
-
The output voltage is limited to 35 V once more
