Blown fuse in plasma cutter

[iain cant]

Hi,
Finally got my plasma CNC running smooth for a full week! Only to try a restart after another good cut and get no response from the plasma..

No power, Nothing. After checking plug fuses I went to the operator manual and located a big fuse inside the box. Continuity test proved it to be blown.

My first question is, why would it blow?

And secondly, I can't find a replacement fuse anywhere. The best offer has been £15 and a 7 day wait. The fuse is a cc-tron Time delay and is 0.8amps and 600 VAC.

This is the one:

First things first, I need to get the plasma powering up, so any suggestions as to where I can get my hands on this fuse would be most welcome..

i think you are going to struggle to find one of those. try RS components or cpc. would be very surprised if maplin has one

I looked on Farnell and RS - no results found. Farnell can do a 1A
