20-Gallon Two Stage Gasoline AGW-SH22-20M


Offering the convenience of three machines in one, this model combines a 220-amp arc welder, two-stage air compressor and a 5000-watt generator with a 688cc Honda GX690 OHV engine. You'll save space and money and reduce your load capacity with this new combination unit. And with only one engine powering these components, you'll also save time on serving parts and maintenance.
