Union AlMg 4,5 MnZr is a solid MIG/MAG electrode wire for welding aluminium and its alloys. It works on frames, tanks, housings and light structures.
The wire is fed continuously from the feeder and welded under shielding gas, both by hand with a semiautomatic torch and on mechanised stations. It goes into transport, the food industry and structures built to resist atmospheric corrosion.
- Classification EN ISO: 18273 S Al 5087 (AlMg4.5MnZr(A))
- AWS classification: A5.10 / SFA-5.10 ER5087
- Shielding gas: I1, I3
- Approvals: DB (61.132.04), DNV, CE
Push the torch and keep the wire path in the feeder short and straight, aluminium coils up easily in the liner. Match the drive rolls to the wire diameter and check the liner, wire slip shows up at once in an unstable arc. Watch the wire stick-out from the contact tip, too long a one lowers the arc voltage and worsens the fusion.
