In this example, the following result is obtained for duty cycle ED:
ED =
" If different weld times or cycle times occur within the application,
use
• the longest welding time and
• the shortest cycle time to calculate the duty cycle.
Look for the inverter‐specific load diagram in section 5.3.3 on page
2.
244 et seq.
First draw the vertical at the previously calculated duty cycle (refer to
3.
point 1.: duty cycle ED = 20 %).
Use the respective characteristics to determine the maximum
4.
permissible primary continuous current or primary peak current.
