Description
The Crown CT34070 3-in-1 Multi-Function Workstation eliminates the need to transport three separate heavy-duty machines by combining an electric generator, an industrial air compressor, and an MMA stick welder onto one frame. Designed for service trucks, field maintenance crews, and off-grid job sites, this versatile unit delivers all core power capabilities while minimizing equipment footprint.
The onboard generator provides 4,000W (4 kW) output at 230V AC alongside a DC 12V output, backed by a synchronous alternator and an analog voltmeter for real-time monitoring. The integrated 1.1 kW air compressor generates up to 8 bar (115 PSI) pressure at 2,880 RPM, providing steady airflow for pneumatic tools and tires. For structural metalwork and repairs, the built-in MMA welder provides adjustable current from 50 to 180 Amps, accommodating 2.6 mm to 4.0 mm electrode diameters.
Built for smooth operation in harsh environments, the CT34070 features an easy-start ignition system with both electric key-start and manual recoil backup, an integrated low-oil level indicator to protect internal components, and a heavy-duty frame.
