equivalent weld cable sizes.
In the table below, when multiple numbers are indicated separated by a hyphen,
the number to the left of the hyphen indicates how many cables are to be used, and
the number to the right indicates the size of the cable to be used. For example,
3-3/0 indicates that 3 cables of 3/0 gauge need to be used for electrode and work
connections.
