Campbell Hausfeld GR3200 3-in-1 Air Compressor, Generator & Welder

30-Gallon Two-Stage Air Compressor • 5,000 Running Watt Generator • DC Stick Welder • Honda GX390 Engine

Bring three essential jobsite machines together in one rugged package with the Campbell Hausfeld GR3200 3-in-1 Air Compressor / Generator / Welder. Built for contractors, mobile service crews, farms, maintenance operations, and industrial applications, the GR3200 combines a high-pressure two-stage air compressor, 5,000-watt generator, and DC stick welder on a single heavy-duty platform.

Power comes from the proven Honda GX390 commercial-grade engine, featuring both recoil and electric starting. With a 30-gallon ASME-certified air tank, up to 175 PSI, 6,000 surge watts, and welding output up to 200 amps, the GR3200 is designed for serious field work where dependable compressed air, electrical power, and welding capability are all needed.

Three Professional Functions in One Machine

Two-Stage Air Compressor

The GR3200 uses an oil-lubricated, cast-iron, two-stage compressor pump capable of producing up to 175 PSI.

Air delivery includes:

• 15.2 SCFM @ 40 PSI
• 14.0 SCFM @ 90 PSI
• 13.7 SCFM @ maximum pressure

The combination of high pressure and strong airflow makes the compressor suitable for pneumatic tools ranging from impact wrenches and ratchets to grinders and spray equipment.

5,000-Watt Generator

When electrical power is needed away from a fixed utility connection, the GR3200 provides:

• 5,000 running watts
• 6,000 surge watts
• 60 Hz output
• 120/240V class electrical service
• Two 120V GFCI outlets
• One 240V GFCI outlet
• 2-pole brushless alternator

This allows the unit to power compatible tools, work lights, battery chargers, and other electrical equipment directly at the jobsite.

DC Stick Welder

The integrated DC stick welder provides adjustable output for field repair and fabrication.

Published welding specifications include:

• Adjustable output: 50–180 amps
• Maximum output: 200 amps
• 100% duty cycle at 150 amps
• 65% duty cycle at 180 amps
• Electrode range: 1/16"–1/4"

This makes the GR3200 particularly useful for service trucks and remote operations where welding equipment may be needed without convenient access to utility power.

Honda GX390 Commercial Power

At the heart of the GR3200 is the Honda GX390, a widely used commercial-grade engine designed for demanding power-equipment applications.

Features include:

• Gas-powered operation
• Recoil start
• Electric start
• 12V alternator
• 1.6-gallon fuel tank

The self-contained gasoline power source allows the compressor, generator, and welder functions to be used at remote jobsites where electrical service may not be readily available.

Built for Mobile & Jobsite Applications

Despite combining three pieces of equipment, the GR3200 keeps everything mounted on one integrated platform. The horizontal air tank incorporates forklift slots, allowing the complete machine to be moved with appropriate material-handling equipment.

At 591 lbs., the GR3200 is better suited to service trucks, trailers, permanent jobsite setups, and industrial work areas than frequent manual relocation.

Ideal Applications

The Campbell Hausfeld GR3200 is well suited for:

• Mobile service trucks
• Construction crews
• Equipment repair
• Farm and agricultural maintenance
• Field welding
• Heavy equipment service
• Industrial maintenance
• Remote jobsites
• Fabrication and repair work
• Pneumatic tool operation
• Emergency or temporary jobsite power
