Why does only the tip of the electrode melt …
In MIG welding(gas metal arc welding or GMAW), this is what you want. In MIG welding, the electrode is a conductive wire that is fed from a spool of wire at high speed. The wire melts and becomes part of the weld. The polarity is reversed so that the wire is positive and the work piece is negative. You don''t need a arc starter with MIG.
