Is there a difference between an aluminum welder and an electric welder?

There is an essential difference between the two.

Welding of aluminum: the gap is supplemented by melting of aluminum. Ordinary aluminum alloy is generally welded by argon arc welding, and there are 4 series, 5 series and 6 series welding wires. However, if welding thin aluminum parts, or dissimilar aluminum, and two different aluminum, we can use WE53 for low temperature brazing at 400℃.

Electric welding: melting the material itself at high temperature to bond the gap. Electric welding is a common name for arc welding. It is a welding operation where covered electrode is used to melt metal parts at high temperature and need arc connection.
