vintage westinghouse stick welder

[shop hermit]

I recently aquired an old Westinghouse 130 amp stick welder and need some information on it. The front panel with the lead receptacles had the ground and heat information painted on and the information has all faded away. Am hoping someone might have that information (or even a wiring diagram). Information on the tag reads Westinghouse 130 amp, type WT-13C, style 14567005. Sn 7. there are 5 holes horizontally across the top and 4 vertically on the right side. Called westinghouse, they sold welder intrests back in the 80's, called the number they gave me and THEY sold to someone else. Called the third party and that number is no longer in service, so I am at a dead end. I cleaned it up and have it working, but am not shure of heats and ground locations. Anyone have one of these old boxes out there???
