(1) Welding current axis
(2) Time axis
Current time = 400 ms
Welding cycle time = 2000 ms
DC_Inverter = 400 ms/2000 ms x 100 % =
20 %
IMPORTANT! The inverter user documentation will be supplied with your system or
can be requested from Fronius Technical Support.
Calculating the maximum permitted welding current in the inverter load diagram
- Find the inverter load diagram
- Draw a vertical line on the diagram for the calculated inverter duty cycle
(DC_Inverter)
- Multiply the primary current read off by the transformation ratio of the transformer
(e.g. 38) -> I_max_Inverter
Calculating the maximum permitted welding current
The maximum permitted welding current is the lowest of the three calculated currents
for the diodes (I_max_Diodes), transformer (I_max_Transf) and inverter
(I_max_Inverter)
