Ensure the welding cables connections are made correctly.
Be sure to connect the cable to welding output terminals securely. Otherwise,
welding output terminals may burn out by heat caused by poor connections.
Do not use a cable without the DINSE connectors. If you use a cable with the
insulation peeled off partly, to bind to an output terminal, the output terminal may
burn out by the heat caused by poor connections and a bare part of the cable may
touch the bonnet and short-circuit.
