Everyone knows the type and performance/limitation of the welder. Another very important step is how to set the parameters. Follow the tips below: Buy a set of aluminum wire feeding tools; pay attention to the wire feeding when welding aluminum. More important, so it is highly recommended to purchase a special aluminum wire feeding tool, a set of tools will contain the following items: 

Non-metallic liner - designed to minimize delivery 

Wire Friction 2. U-groove drive roller - used to avoid breaking or deforming the soft aluminum wire.These drive rollers do not scratch the aluminum wire like the V-groove roller. If the V-groove roller is used, the wire scraping liner will be blocked and the wire feeding failure will occur. 

Import and export guides - designed to avoid wire scratches 

Contact Head - The contact head used in the welding of aluminum has a larger diameter opening because it produces more expansion than steel when the aluminum wire heats up. Therefore, the size of the aluminum wire dedicated contact head is small enough to maintain electrical contact while being sufficiently flexible to allow expansion.
