That seemed to be a response after testing lots of cheap chinesium

permit.

We only found out about the 10A fuse when I got some wallah around to do
a bit of welding. Since this was very light gauge stuff which I can't be
doing with, I got this specialist bloke in. He'd been using it on and off
for about 4 hours before the fuse in the reel finally gave up the ghost.
Poor bugger had been cussing about not being able to strike up as
smoothly as he usually could so it looks like his MIG was being current-
starved by a fuse that was 3A less than it should have been for that load.
Had it not been for that incident, I'd most likely never have known!

Fuses don't do that. A long lead made with thinner wire than claimed
might do it.
