ELECTROMAGNETIC COMPATIBILITY
The welding device is in terms of interference designed primarily for industrial
areas. It meets the requirements of EN 60974-10 class A and it isn’t designed
for using in residential areas, where the electrical energy is supplied by public
low-voltage power supply network. It can be here potential problems with
ensuring of electromagnetic compatibility in this areas, due to interference
caused by power lines as well as the radiated interference.
During operation, the device may be the source of interference.
Caution
We warn users
, that they are responsible for possible interference from
welding.
