Aluminum Welding Cable

The more the operator can narrow down the melting range of the metal the easier it will be to weld the alloy.

Diameter size of aluminum wire 0 030 or 0 035 for example hobart recommends 0 035 to be used with 1 16 to 1 4 inch thick base metal. Mig welding wire for aluminum this er4043 wire is for aluminum 43 356 3003 3004 5052 6061 and 6063. Argon gas is used as a shield during the welding process. The requirement to use shielding gas with aluminum welding wire means that you will need a mig welder capable of using shielding gas.

Obtain wire that is 3 64 or 1 16 inch diameter. That along with a cylinder of 100 argon welding gas and a small spool of solid aluminum wire is an efficient and reliable method. Select an aluminum filler wire that has a melting temperature similar to the base material. Er 4043 or er 5356 is ideal for most jobs.

For some jobs a mixture of argon and helium can be used instead but this is very much job dependent. This wire creates stronger welds than standard mig welding wire for aluminum. The larger the wire diameter the easier it feeds.
