Perhaps this fuse should be a "T" type or delayed acting (antisurge fuse) . If the fuse has been replaced by an "F" fast acting fuse then this could explain why they are blowing.

Bits: It's useful to have a small selection of manufacturer's bits (soldering iron tips) available with different diameters or shapes, which can be changed depending on the type of work in hand. You'll probably find that you become accustomed to, and work best with, a particular shape of tip. Often, tips are iron-coated to preserve their life, or they may be bright-plated instead. Copper tips are seldom seen these days.

Louis D Biasi You resurrected a 12 year old unanswered question which will now stick on the Homepage, 'Unsolved' despite being answered. It is always better to make a squeaky fresh, clean question of your own.
