Do welding electrodes need to be used for the welding machine? Will there be smoke and dust in the welding process?
Butt welding machine is also called impact welding machine, the welding machine voltage is very low, the current is very large, the use of two pieces of metal collision, short circuit, high current welding. Soot is not large, but there is an arc of shallow metal dust.
Without electrode. Basically no smoke and dustTwo metal charged collision, instantaneous short-circuit discharge
The welding machine does not need to use the welding rod, and the welding machine uses the welding flux as the common arc welding machine. In fact, it is a big welding rod. The soldering flux is added around the butt joint material, and there will be smoke and dust in the welding process.
