That may be a big factor for you to consider if this is your only machine and using if for both. It's called "gun on demand" capability. Ja
It is true that it is a bit more trouble to switch to the push-pull...

BUT in either case you will still need to change gasses and purge lines... even with "gun on demand"...

the Alumapro push pull is only worthwhile if you are going to push a lot of aliuminum at a time... the 30A is great for small repairs.. where the 1 pound limit on spools is not a hinderence...
