(....this is slightly off topic---> but rather important)

I am planning on using an arc welder for my next huge power supply. However, 
I am curious about typical arc welder output volts on a 240V AC welder.

I am curious if AC arc welder voltage output stay the same as the input 
voltage/ and amperage is the only thing being regulated or changed??

Has anyone ever measured the output voltage of an arc welder with a 
multimeter??
(I am looking for 130-170 VAC output to my large transformer bank)

I have a series of 3 (4500 VAC 450 mA) photocopier transformers, and I 
really don't want to destroy them!!
