I'm a little stuck... Click here to teach me more about this clue!

'one sticks by melting point' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'see tungsten from earlier' is the wordplay.
'see' becomes 'spot' (to spot is to notice or catch sight of).
'tungsten' becomes 'W' (W is the chemical symbol for tungsten).
'from' says to put letters next to each other.
'earlier' becomes 'elder' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'spot'+'w'+'elder'='SPOT-WELDER'
