Would you like to weld yourself?
No, electric soldering iron, then how to burn to the melting point of copper, copper melting temperature is 1084.6'C, you can only buy a small tin welding of butane gas with oxygen
If the copper tube is not very thick, you can use a high-power electric soldering iron, 150--200W electric iron, solder wire must be better
The temperature of the electric soldering iron can not meet the requirement. It is better to use oxygen explosion
