Sogou Input Method - Online Translation
Multi-strand composite solid welding wire with a diameter of 2.4mm uses a gas mixture of 80% argon and 20% carbon dioxide, which is about 40% faster than using 1.2mm diameter wire. The arc is easy to control, the voltage isn't too high, the weld looks nice, and there's no spatter. If you look at the multi-strand composite wire individually, you can see that each strand is very thin, which increases the heat-absorbing area of the wire, lowers its melting point accordingly, and reduces the amount of heat input. Advantages: lower heat input, faster welding speed, higher efficiency, no pollution, and reduced energy consumption.
