“I spent the afternoon with Paul Nippes of Magnetic Products and Services of Holmdel, NJ. He came to…demagnetize…tubes. Unfortunately, these tubes had already been demagnetized by…personnel using the 1200 amp AC Submerged Arc welding power supply, because they didn’t have much residual magnetism in them. However, the vendor [MPS] attached his setup to each of the tubes and reduced the remaining residual magnetism in the tubes to extremely low levels. I can confirm that the magnetism left by him [Paul Nippes] in the tubes is less than the best we ever got using the subarc power supply.”
