Hello,  I have a good condition 15KVA industrial spot welder that I normally would not max out welding heavy items with, just light sheet metal usually.  Have used a 10-20 KVA miller spotwelder (looks like overgrown portable on a stand) with a 50 amp circuit breaker.  It rarely  blew the breaker.  I will be running my own spot welder with a maximum of 60 amps 230v 1ph for the whole shop.  I can feed 60 amps directly off the box and make the lights suffer bumps.  It's an old fuse panel which can be fitted with slow blow fusetron 60 amp fuses.  Are these slow blow fuses sufficient for spot welding 18ga steel?  Have a flashlight just in case.  The literature that came with this unit stressed big wiring as an aid to  good performance, and the incoming wiring to the fuse box is at least 4, probably two.  Small stick welders supply wiring in a shop just uses #6 for 50 amp, by the book anyway. I would only need 10' of flexible #2 welding cable to hook directly to the box, is this necessary for just 10'?Thanks,Alan
