Aluminum MIG welding

[alba94]

Hi friends,
What kind of gas do you use for aluminum MIG welding?

Aluminum requires some particular changes for welders who are usual to welding steel. It's a substantially milder metal so the sustain wire must be bigger. Aluminum is likewise a superior conductor of warmth, so welding aluminum requires more control over the power supply and the nourish rate of the anode.
