Hi,

I spent the weekend setting up my new PM205. Since the user manual was written for the older design, I have had to make a few guesses on what the controls do.

As far as I can tell, the Pulse current knob sets the peak current, and the foot pedal knob controls the base current limit. With the pedal, you can control the base current from some minimum number up to the limit that you set with the knob on the pedal. Is this true? (It is hard to weld and watch the current readout at the same time!). If so, is the knob on the foot pedal a 0-100% scale of the Pulse current setting, or some absolute (like 10-200A)?

If you are not using the foot pedal, how do you set the base current?

Lastly, AC welding aluminum felt 'agressive'. Is there a minimum thickness of Al that this machine is capable of?

thanks,
casey
