How many amps input from a 9v power supply is ok. ie. 0.6amp, 1.0 amp, 1.5 amp ???

I don't know because mine had a floating input on U1 and that caused overheating of U1 until it ceased to work. I had an open pull up resistor, R24 10kΩ, that caused the input to float when the rotary encoder, SW6, happened to be in the open state . My DSO Model 150 pulls the voltage down on a 9V alkaline battery from 9.37V to 8.66V when it should have been about 9.3V. You might try a 9V battery and see how much it pulls down the voltage. From the discharge curves at various loads on a 9V alkaline battery, I would say that the DSO should require <0.05A.

is ok for car testing

I am not sure what your asking? I wouldn't use it to test engine timing or anything around it since its a 12v system. This oscilloscope can only handle 3 - 5 volts. You would need to get probes that can handle higher voltages.

Will this measure AC line voltage such as a generator output?

Sure, but you would need a 1x/10x probe . WARNING: AC line testing can be dangerous! Only proceed if you have experience and/or training. Thanks

If i got a better probe, would i be able to test a 50v 200a dc welder output? if so, what kind of probe would i need?

just use a multimeter on 200 Vdc range.
