The Lc40 fits 2/0 welding cable.

will these work on a 250 amp welder ?

I ran it at 200 on a classic 300D and melted the whole plastic over the screw to get it undone

What about 1/0 connectors?

This connector set is recommended for 1/0 to 2/0 welding cable size.

Will these work with 3/0 wire?

No, you will need the lc40HD for that size
