Klutch ER4043 Aluminum MIG Welding Wire 1-Ib Spool

Klutch ER4043 aluminum MIG welding wire is a general-purpose aluminum welding wire. It's one of the oldest and most widely used welding and brazing alloys. This aluminum alloy contains silicon additives, which result in improved fluidity (wetting action) of the weld pool and also produces a weld that's less sensitive to cracking. Its bright weld finish makes it a popular choice for welders. ER4043 can be used to weld various grades of aluminum. This product requires a shielding gas: CO2 and/or CO2 mix.
