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-SH22-20M combination air compressor, generator, and arc welder is the ideal tool for field repairs in remote locations. Powered by a robust 688cc Honda GX690 OHV engine with electric start, this three-in-one powerhouse delivers 30.5 CFM at 90 PSI through its two-stage cast iron compressor, generates up to 5000 watts of AC power, and welds at up to 220 amps with a 40% duty cycle. Save precious room on your service truck with this versatile all-in-one solution designed for contractors, farmers, and professionals who need reliable compressed air, electrical power, and welding capability—all from a single unit.
When you're working in the field, every piece of equipment you bring along takes up valuable space and adds weight to your truck or trailer. The AGW-SH22-20M solves this problem by combining three critical tools into one compact, powerful unit. Whether you're running pneumatic tools, powering job site equipment, or performing critical welding repairs, this combination unit handles it all without sacrificing performance.
Built around the industry-trusted Honda GX690 engine, this unit delivers dependable starting and long-term reliability even in demanding conditions. The two-stage cast iron compressor provides exceptional air delivery with 30.5 CFM at 90 PSI from its 20-gallon ASME coded receiver tank, ensuring you have the air volume needed for sustained tool operation. The brush-type 2-pole alternator with 100% copper windings generates clean power with less than 6% total harmonic distortion, making it safe for sensitive electronics and power tools alike.
For welding applications, the integrated arc welder offers impressive versatility with an amperage selection switch allowing you to choose between 170A or 220A maximum output. With a duty cycle of 220A at 40%, 190A at 60%, or 150A at 100%, you have the flexibility to tackle both light fabrication and heavy-duty repairs. The 50-220A working range covers virtually every stick welding application you'll encounter in the field.
The AGW-SH22-20M is built with components designed for demanding commercial and industrial applications. The splash-lubricated compressor pump features an oil level sight indicator for easy maintenance monitoring, a large canister intake filter to protect against contamination, and a stainless-steel braided discharge hose for durability. The compressor is equipped with a regulator and two gauges for monitoring both tank and outlet pressure, plus manual drain valves for proper maintenance procedures.
The generator section utilizes 100% copper windings in its brush-type 2-pole alternator, ensuring efficient power delivery and long service life. With total harmonic distortion (THD) less than 6%, the electrical output is clean enough for powering computers, control systems, and other sensitive equipment. The unit provides (2) 120V, 20A GFCI duplex receptacles and (1) 120V/240V, 20A twist-lock receptacle for maximum flexibility in connecting tools and equipment.
Operating modes are straightforward and purpose-designed. Generator Mode delivers AC current only, with the selector switch set to idle down or full throttle depending on load requirements. Welder Mode provides DC current with the engine running at full throttle and the selector switch set to full throttle, ensuring consistent arc performance. When operating under combined loads, the unit delivers 4500 watts continuous on-load at 90 PSI, giving you simultaneous air and power capability.
Measuring 47" L × 24" W × 50" H and weighing 803 lbs, the AGW-SH22-20M is designed to be transported on a service truck, trailer, or job site location where it can serve as a central power, air, and welding station. The powder-coated frame and 14-gauge powder-coated belt guard provide protection against the elements and jobsite wear, while the powder-coated ASME coded receiver tank ensures structural integrity and longevity.
The unit comes equipped with a 150-PSI maximum rated regulator, allowing you to dial in the perfect air pressure for your pneumatic tools and equipment. Whether you're inflating tires, running air hammers, operating grinders, or powering spray guns, the precise pressure control and high CFM output ensure optimal tool performance.
