Computers in the 60's were very sensitive to power fluctuations.  They were build around discrete components, no chips back then and switching power supplies were still in the future.

A friend told me that in the 1960s he worked for a small company with a
mainframe computer. It sometimes worked well but sometimes acted as if it

in their little industrial park. Turned out that one nearby company ran
several heavy-duty arc welders.
