Sounds like he needs a 0.37 ohm resistor to allow a 35A current at 13V. Better
make it a 500w resistor or better to handle that kind of current.
I agree, it sounds like the P.S. is working properly.

No it's not working properly. When set at 13V and the current knob all
the way counterclockwise (no current), when connected to a power
resistor it should maintain 13V and put out no current. Instead, it
puts out 2 amps and the voltage drops to 6V.
How can any PSU disobey Ohm's Law?
V = I * R
13 = 0 * 3 ???????????
