1 Weld Output Cable
Determine total cable length in weld
circuit and maximum welding am-
peres. Use Section 3-5 to select
proper cable size.
Use shortest cables possible.
Do not use damaged cables.
2 Terminal Lug
Use lugs of proper amperage
capacity and hole size for connect-
ing to MOG terminal, and weld out-
put terminals and work connection.
