Good morning all,
Im currently planning to build a sheep handling system which will consist of hurdles and gates and once i get brave maybe a shedding gate or weigher..

i'll be running off my home 13amp fuse so 130amp max setting should keep my fuse in trak.

I will be making these hurdles out of 20mm box x 2mm thick.

what size wire would you reccommend to ensure good weld with Mild steel as above size?
