Melting Fuse Blocks

I have a fuse problem. Three fuse plastic open clip mounted in a disconnect box with Littlefuse JTD 20 fuses for a welding machine. Service is from 480VAC and the disconnect/fuse block is fed from a three phase panel with a 60 amp breaker. This is the second one where one fuse melts out the back opp
