Circuit board technology

Miller Electric's patented Vault technology protects the electronics -- and controlling output -- of a machine in heavy industrial applications by providing a clean circuit board environment. Created out of two aluminum halves sealed with silicone, as well as a water-tight harness for connections, this technology hermetically seals the circuit board and is impenetrable to dirt, dust and moisture. Without the sealed environment, circuit boards are exposed to harsh elements that can disrupt the electronics, and therefore the operation of a welder/generator. Based on warranty claims versus number of products sold with the new Vault technology, Miller's Big Blue CC/CV welder generator shows a 98.8-percent reliability rating (January 2006 to the present), while the Pro 300 has a 98.1 percent rating (June 2006 to the present).
