ER4043 is the most widely used general-purpose aluminum MIG/TIG filler — an aluminum-silicon alloy that produces a smooth, fluid weld pool with excellent crack resistance and low spatter. The wire is softer than 5xxx fillers, so long push-only guns benefit from a spool gun or push-pull feeder.ER4043 是用途最廣的通用型鋁焊線——鋁矽合金,焊池流動性佳、抗裂性優、噴濺低。線材較 5xxx 焊材軟,長距離推式送線建議搭配槍上送絲或推拉式送絲機。
