hello all,
i had the oppertunity to aquire several welding transformers... one is marked 3400-0-3400 secondary and is tradional E & I construction (14" tall x 12" wide x 10" deep) the other one is unmarked except for 'UNIVERSAL VOLTRONICS' It is steel band in construction. there are 5 primary lugs... if i put 12VAC across pri. i get 4" spark on a SS spark gap...


is there any info out there or tests that i can do to figure out some specs.?? FYI - the 3400-0-3400 has 148 ohms across sec. the 'UNIVERSAL VOLTRONICS' is 1043 ohms across sec.
