‘Vault’ seals and protects electronic circuit boards from dirt, dust, moisture
Found only in Big Blue 400, 500 and Air Pak models and PRO 300 CC/CV series of diesel engine-driven welder/generators, the Vault creates a hermetically sealed environment to completely protect the printed circuit board inside it, ensuring more than 98% reliability and true constant voltage output. Created from two aluminum halves sealed with silicon plus a watertight harness for connections, the Vault eliminates exposure of PC board to harsh elements that disrupt electronics and machine operation.
