Wire - MIG Aluminium PROMAX 4043
4043 grade MIG wire for welding a wide range of aluminium alloys. Especially suited for 6xxx series alloys. Offers excellent crack-resistance, fluid weld pool and is preferred by some welders because it “wets and flows better” and it also makes brighter looking welds. Manufactured with strict quality-control, layer-wound for reliable wire feeding. Available in 1.0mm & 1.2mm x 6kg.

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 65°C
- Joining dissimilar 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:
