[Boatanchors] Weller Soldering tips

[David C. Hallam]

I went out to my shop and looked at the 250W gun I though was a Weller.  
It  is actually a Wen.  It looks just like the one in your picture.  
However,  all the other Wen solder guns I have had from 150W to 60W and 
and I have had several, used a tube type tip like I described.  I don't 
have one any more to photograph.

"Nip the shoots of arbitrary power in the bud, is the only maxim which can ever preserve the liberties of any people. When the people give way, their deceivers, betrayers, and destroyers press upon them so fast, that there is no resisting afterwards. The nature of the encroachment upon the American constitution is such, as to grow every day more and more encroaching. Like a cancer, it eats faster and faster every hour. The revenue creates pensioners, and the pensioners urge for more revenue. The people grow less steady, spirited, and virtuous, the seekers more numerous and more corrupt, and every day increases the circles of their dependents and expectants, until virtue, integrity, public spirit, simplicity, and frugality, become the objects of ridicule and scorn, and vanity, luxury, foppery, selfishness, meanness, and downright venality swallow up the whole society."
-- John Adams, Novanglus Letters, 1774
