DUTY CYCLE

The welding unit describes an output characteristic of a "constant current". The duty cycles following the norm
EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table below :

Note : The machines' duty cycle has been tested at room temperature (40°C) and has been determined by
simulation.
