AGW Series air compressor/generator/welder combo, one gasoline engine driving all three functions. The 20-gallon Honda model is a genuinely larger tier, nearly double the compressor output, welder amperage range, and price of the 30-gallon/base-mount Mi-T-M or Vanguard models. Honda and Vanguard engines are 49-state, not sold in California; Mi-T-M has no restriction.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

Mi-T-M's AGW Series combines an air compressor, generator, and welder into one gasoline-engine-driven unit, built for a crew that needs all three functions on a service truck or trailer without carrying separate machines. The line splits into two real tiers, not just a size choice: the 20-gallon Honda-engine model delivers nearly double the compressor CFM, welder amperage range, and price of the 30-gallon or base-mount Mi-T-M or Vanguard models, which are otherwise the smaller, lower-output configuration.

Generator and welder draw from the same engine but operate as distinct modes: Generator Mode runs AC current only, with the idle-down feature enabled and the switch set to full throttle; Welder Mode runs DC current only and requires the engine at full throttle with the selector switch set accordingly. Three engines are available: Honda (20-gallon model only), Mi-T-M, and Vanguard (the latter two each offered as a 30-gallon tank or tankless base-mount). Honda and Vanguard are both 49-state engines not sold in California; the Mi-T-M engine carries no such restriction.

Common Applications

  • Field welding, air tool operation, and portable power from one machine on a service truck or trailer
  • Utility, fence, and service-truck work where a crew needs to weld, run air tools, and power electronics without hauling three separate machines

Selection Notes

  • The 20-gallon Honda model is a genuinely different tier, not a size pick: nearly double the CFM, welder amperage range, and price of the Mi-T-M/Vanguard models
  • Honda and Vanguard engines are both 49-state and not for sale in California; only the Mi-T-M engine has no restriction
  • Mount choice (30-gallon tank or tankless base-mount) is available on Mi-T-M and Vanguard engines; the Honda model is 20-gallon tank only, no base-mount option
  • Generator output holds flat at 4500 watts regardless of compressor load on the Honda model, but drops from 3000 to 2500 watts under compressor load on the Mi-T-M/Vanguard models
