Dependable high quality equipment is vital in every industry, so is working with equipment that can save both time and money. The Mi-T-M AGW-SM14-B combination air compressor, generator, and arc welder is the ideal tool for field repairs in remote locations. Save room on your service truck with this versatile all-in-one solution that delivers professional-grade performance across three critical functions.
This base-mount configuration is designed for maximum flexibility—whether you're mounting it permanently in your truck bed, trailer, or workshop space. Powered by a reliable 420cc Mi-T-M OHV engine with electric start, the AGW-SM14-B delivers 16.4 CFM @ 90 PSI from its two-stage, cast iron compressor pump, 4500 watts rated AC output from its generator, and 150A @ 100% duty cycle welding capability—all from one compact, 384 lb powerhouse.
Three Tools, One Powerful Solution
The AGW-SM14-B isn't just a compressor—it's a complete mobile workshop. Whether you need compressed air for pneumatic tools, AC power for lighting and electric tools, or DC welding current for field repairs, this unit handles it all without the need for multiple machines taking up valuable truck space.
Compressor performance: The two-stage, splash-lubricated cast iron pump delivers 16.4 CFM at 90 PSI and 15.7 CFM at 175 PSI, providing the air volume and pressure needed for impact wrenches, air tools, and tire inflation. The unit features a stainless-steel braided discharge hose, large canister intake filter, and oil level sight indicator for easy maintenance.
Generator capability: With a 5000-watt maximum / 4500-watt rated AC output, the brush-type 2-pole alternator provides 60Hz power at 120V/240V. The unit features 100% copper windings and less than 6% total harmonic distortion (THD), ensuring clean, safe power for sensitive electronics. Equipped with (2) 120V, 20A GFCI duplex outlets and (1) 120V/240V, 20A twist lock receptacle, you have flexible power options for every jobsite need. Continuous on-load power output is 3000 watts at 90 PSI and 2500 watts at 175 PSI when running the compressor simultaneously.
Welding power: The integrated arc welder delivers DC current with a 50-170A working range, providing 150A at 100% duty cycle (based on 10-minute run time). The amperage selection switch allows you to dial in the exact current needed for your welding application, from light fabrication to heavy repairs.
Built for Reliability and Easy Operation
At the heart of this combination unit is the proven 420cc Mi-T-M OHV engine running at 3600 RPM. The engine includes electric start capability (battery and battery cables not included), making startup effortless even in cold weather or remote locations. The compact 1.85-gallon fuel tank provides extended runtime while keeping the overall footprint manageable for truck or trailer mounting.
Operation modes are clearly defined for safety and optimal performance. Generator Mode provides AC current only, with the selector switch set to either idle down or full throttle depending on load. Welder Mode requires DC current only, and the engine must be running at full throttle with the selector switch set accordingly. This ensures each function operates at peak efficiency and prevents damage to the equipment.
The rugged frame features a 16-gauge powder-coated belt guard for durability and protection in harsh work environments. The unit is equipped with a regulator and two gauges to monitor both tank and outlet pressure, manual drain valves for proper maintenance, and a 16.5-inch flywheel for smooth, balanced operation. The unit is equipped with a 150-PSI maximum rated regulator for safe, controlled air pressure.
