Big Blue® 800 Series

The most powerful lineup of diesel welder/generators in the industry.
The Big Blue 800 Series offers 800 amps of weld power and 27,000 watts of peak generator power and is ideal for dual-operator applications on labor intensive jobsites, or jobsites with limited space.

Heavy-duty low-speed T4F and T4i industrial diesel engines.
The cleanest, greenest diesel power available. Utilizes diesel oxidation catalyst (DOC) technology in T4F models to keep the air clean with NO exhaust aftertreatment maintenance.
