GENERAL

This specification sets forth the minimum requirements for a diesel engine driven welding machine that is self-contained and fully enclosed.

Equipment shall be new, a production model of current manufacture, and must meet all state and Federal safety and emission standards in effect at time of order.

REPRESENTATIVE SPECIFICATIONS

A Miller Big Blue 400 Pro, with appropriate options and standard features, was used to develop these specifications and establish equivalency evaluation criteria.
