Wire - MIG Aluminium PROMAX 4043
How to set up your MIG welder for aluminium welding
Aluminium MIG Wire Selection Guide
KEY FEATURES
> Excellent crack resistance
> Added silicon content (5%) increases fluidity of the weld pool
> Lower melting point and fluidity vs 5xxx series wires
> Preferred by some welders for an aesthetically superior weld finish
> Often chosen where balance of strength & ductility is required, such as materials subject to bending, flexing or forming
> Low welding smut and discoloration
> Low shrinkage rate / reduced distortion
APPLICATION INFO
> Ideal for 6xxx heat-treatable alloys, including 6061 & 6063
> Can be used for selected 1xxx & 5xxx alloys, although ER5356 or ER5183 wires may be a better choice for 5xxx
> Repair of aluminium alloy castings (mainly 4XX and 6XX Series)
> Suitable for use in elevated temperature applications, where service temperature may exceed 65c
> Joining dissimiliar grades
OPERATING INFO
> All-positional
> Polarity: DC+ (Wire/torch positive, Earth negative)
> Shielding Gas: 100% Argon
> Wire brushing between each pass is recommended to ensure removal of surface oxide build up
CLASSIFICATIONS
> AWS 5.10 ER4043
