   Just wondering if using too small a fuse can choke the current? Even   
   though they're only an inch long?   
   Say I am running my portable welder which draws 12A and is fitted with a   
   13A fuse, via an extension lead which is fitted with only a 10A fuse,   
   will the smaller fuse choke the current the welder is trying to draw?   
   IIRC, the smaller fuse would probably not blow for many minutes, so one   
   could be totally unaware that it's unable to supply enough current for   
   the welder and giving rise to poor quality welds.
