Hello i'm trying to figure out if an ESAB EPP-600c Power Supply can replace an EPP-450 Power Supply.

I've read in the manuals they're both compatible with smart flow 2 system, and some of the same torch heads.
Other then the output being higher on the epp-600c is it capable of working on a system that currently has an epp-450.

... I am not familiar with these machines, i'm trying to help a friend find more information.
I apologize if this isn't enough information to produce an answer, I will get more info if needed.

Thank you!
