0.4mm copper wire and 0.2 copper wire welded together. Can electric iron be used for welding directly? How many degrees do you need?
But to do this effect of welding crafts, the efficiency is not expected to be fast, and the joints of the flux to clean it.
Soldering can, low cost, low melting point, you can use the electric iron. But first make sure your material is copper, and copper plating is fine.
If it is not used in soldering, brazing is used, the efficiency is relatively high, but the price is a little high. Electric iron will set 300-400 degrees on the line, the temperature depends on the speed of your action, welding action faster, the temperature is higher.
