The CB400/600 has the same switch disconnector's (400A or 600A) but is housed in a compact enclosure with no Amp/Volt meters. Input and output connectors are located 2 at each end of the enclosure.

CB400/600 can be used for either thermic cutting or welding and is recommended for Hydro-Arc™ Gouging.

Where this unit is used for any quality wet welding it is recommended that other arc monitoring is used such as clamp meters.
