ER4043 aluminium MIG wire for general-purpose aluminium fabrication and repair. Use with pure Argon shielding gas; match wire diameter to your drive roll, liner and contact tip.
ER4043 wire for aluminium MIG welding
This aluminium-silicon alloy wire is a general-purpose choice for MIG/MAG welding of weldable aluminium alloys. ER4043 is a common first choice where a wide, forgiving operating window and good wetting are wanted for general aluminium fabrication and repair.
Choose the correct diameter and spool
Select a wire diameter and spool weight that your welding machine and feed system can accept. The drive-roll groove, torch liner and contact-tip bore must match the selected wire diameter, and a U-groove drive roll is recommended for soft aluminium wire to avoid deforming it.
Gas and feed compatibility
- Process: gas-assisted MIG/MAG
- Material: aluminium (ER4043)
- Shielding gas: pure Argon
- Feed setup: U-groove drive roll for soft aluminium wire
