Supply from power generators
The power source can be supplied from different types of generators. However, some generators may not provide sufficient
power for the welding power source to operate correctly.
Generators with Automatic Voltage Regulation (AVR) or with equivalent or better type of regulation, with rated power of
minimum 8 kW 1 phase, are recommended.
