Description

Gas Welder Generator

Welding and Power in One Compact Unit

The gas welder generator series from Multiquip combines reliable welding performance with clean auxiliary power in one versatile machine. Built for construction, agriculture, and equipment repair, these units deliver smooth DC welding output along with up to 3kW of AC electricity for tools, chargers, and lighting. Lightweight, portable, and jobsite-tough, the gas welder generator is the perfect solution for professionals who need both flexibility and durability.

Efficient Dual-Function Performance

At the heart of each gas welder generator is a dependable Honda engine designed for fuel efficiency and consistent performance. Models like the GAW135H and GAW180HEA offer 135 amps and 180 amps of DC welding power, respectively, while also supplying AC output for essential jobsite equipment. Because operators can weld and run tools at the same time, there’s no need to haul separate small generators. This all-in-one system reduces transport weight and streamlines daily operations.

Key Features of the Multiquip Gas Welder Generator

  • Reliable Honda GX Engines – Quiet, efficient, and proven for long service life
  • DC Welding Output – Ideal for mild steel, stainless, and fabrication work in the field
  • AC Power Capability – Run lights, saws, and chargers with up to 3kW of power
  • Automatic Idle Control – Reduces noise and fuel consumption during downtime
  • Durable Steel Frame – Designed for rugged use on demanding jobsites

Portable, Compact, and Field-Ready

Each gas welder generator is built into a heavy-duty frame with top-mounted handles and lift points for easy transport. Weighing under 200 pounds, these units can be loaded by two people and fit easily into a pickup bed or service truck. As a true portable welder generator, they are ideal for roadside repairs, remote property work, or shop welding when space is limited. With their combination of mobility and performance, they outperform many standalone welders and small generators.

Why Contractors Choose Multiquip

For professionals who need reliable welding power and auxiliary electricity, the gas welder generator delivers unmatched convenience. Instead of juggling multiple machines, crews gain one efficient, durable unit that saves time and money. Whether you’re using it as a gas powered welder for fabrication tasks or as a welder generator to power tools on-site, this system provides the all-in-one performance that modern jobs demand.
