Protect your Miller Trailblazer® 330 Diesel with the Miller Protective Cover, stock #301731. This heavy-duty cover is designed specifically for Trailblazer 330 Diesel machines without a protective cage or running gear. The water- and mildew-resistant construction helps shield the welder from dust, dirt, moisture, and jobsite grime while helping maintain the machine’s finish during storage or transport. This is the correct cover for Trailblazer 330 Diesel units that do not have the optional protective cage or running gear installed. For machines with a protective cage or running gear, use the appropriate alternate cover instead.
