What is the advantage of having the spool at the gun, why not just have the
drive system in the gun and leave the spool at the machine. I guess one
reason would be if your gun was far away from the machine. But I am
referring to a 10-15' gun. It would make a small 175 amp mig machine ideal
for small aluminums jobs. I might try this on my Lincoln sp-170.

Aluminum wire is too soft to be pushed through a long gun lead. What I
understand happens is, you get birdsnesting a lot. Google on it. - GWE
