Alum Mig "Kit"
Taken from this link: http://www.lincolnelectric.com/knowl...compactmig.asp
My question is...where can I purchase the "kit" from? I haven't seen it sold anywhere local?
Thanks.
Purchase an Aluminum Feeding Kit
Attention to feeding issues is much more critical when it comes to aluminum welding. It is highly recommended that you purchase an aluminum feeding kit, which includes the following items:
Non-metallic liner - designed to minimize the amount of friction on the wire
U-shaped drive rolls - to avoid crushing or deforming the soft aluminum wire. These drive rolls do not shave the wire like V-groove drive rolls. Using V-groove drive rolls, the resulting wire shavings can clog the liner and lead to feeding problems.
Inlet and outlet guides - designed specifically to avoid wire shaving.
Contact tips - as compared to those used for the same diameter of steel wire electrode, contact tips for aluminum have larger diameter holes, since as aluminum heats up, it expands more than steel. Therefore, contact tips for aluminum applications are sized small enough to maintain good electrical contact, but large enough to allow for expansion.

Re: Alum Mig "Kit"
its tough welding aluminum mig without a spool gun in general. It can be done but you'll be spending a lot of time pulling the wire out and putting it back through. Even with minimal tension.. Once the wire burns back into the tip the driverolls usually keep pushing the wire and break it.
