Rating Plate - ESAB LKA 180 Service Manual

RATING PLATE

The rating plate is secured to the back of the machine. The example shown below is the rating
plate for an LKA 240 with an explanation of how the plate should be read and interpreted.
1. LKA 240 is the type designation for this power source. The first letter, L, indicates that
the LKA 240 is a rectifier, while K indicates Compact (Kompakt in Swedish) and A indi-
cates the design generation.
The 240 indicates the maximum welding current.
2. These symbols indicate that the LKA 240 incorporates a transformer and rectifier.
3. This section indicates the voltage/current characteristic when welding and a current range
of 30 - - 200 A.
The voltage values of 15 and 24 V in the heading indicate that we comply with the in-
ternational arc characteristic as defined in IEC 974- - 1.
X = The duty cycle, indicating for how long a time welding can be carried out at the
specified welding data, expressed as a percentage of a ten- - minute period.
I = The current at the respective duty factors.
2
U = The arc line characteristic voltage.
2
U = The open- - circuit voltage.
