Why The Campbell Hausfeld GR3200 Is Worth The Investment
This isn't just a compressor, it's a genuine 3-in-1 machine combining a two-stage compressor, a 5,000 watt generator, and a 200A DC arc welder in a single ASME certified unit, giving contractors the equivalent of three separate pieces of equipment without the cost, space, or maintenance burden of owning them individually.
The GR3200 specifically addresses the needs of contractors, service trucks, and jobsite crews who need compressed air, generator power, and welding capability all available from a single machine mounted on the truck or trailer.
Three Machines, One Compact Footprint. Eliminating the need for a separate compressor, generator, and welder, this unit consolidates all three functions into one ASME certified package, freeing up truck bed or trailer space that would otherwise be taken up by three individual machines.
Built For Reliable, Multi-Function Performance
The two stage, oil-lubed cast iron compressor pump delivers 14 CFM at 90 PSI with quiet operation and long service life
The 5,000 watt generator provides GFCI-protected 120V and 240V outlets for powering electric tools and lights
The onboard DC arc welder ranges from 50A to 200A, capable of welding up to 1/2-in. thick steel
Engineered For Jobsite Durability And Safety
The UL-certified, OSHA-compliant control panel keeps operation safe and compliant on active jobsites
A heavy-duty 14-gauge steel belt guard is securely bolted for protection but quickly removable for routine maintenance
The reliable Honda GX390 engine features a 12V alternator with recoil or electric start options
Real Savings
Combining three machines into one unit avoids the cost of purchasing a separate compressor, generator, and welder
ASME certification and a two-stage cast iron pump reduce the risk of premature pump failure under heavy use
Consolidating equipment onto one unit reduces the truck bed or trailer space needed for job site equipment
Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately
The Bottom Line Contractors and service crews who need compressed air, generator power, and welding capability on the job site can't afford to haul three separate machines when one unit can do it all. The Campbell Hausfeld GR3200 is built with a reliable Honda GX390 engine, a two-stage cast iron compressor pump, a 5,000 watt generator, and a 200A DC welder, so it delivers genuine 3-in-1 jobsite utility. For anyone who needs air, power, and welding capability on the truck or trailer, this is the machine built to handle all three.
