Older equipment is peaked by increasing filament current until the beam current is stabilized-then adjusting meters accordingly.
The other problem occurs when peak filament currents are too low-often the case when a filament has been peaked for low-beam-current welds followed by use for a setup requiring a higher beam current.
Each cell in the first coil I contains one filament, and the current density in the coil cross section is assumed to be uniform, so that the filament currents are equal.
