●Be sure to crimp a crimping terminal to a cable and connect the cable to welding cable to welding
output terminal. Otherwise the terminal may burn out by the heat due to insufficient connections.
● Use a cable with a crimping terminal. To weld binding bare wires to an output terminal, the terminal
may burn out by the heat caused by insufficient connections and also bare wires may touch the
bonnet to bring short-circuit.
