Multiquip Gas Welder Generators – Reliable Welding and Power in One Compact Unit

Multiquip’s gas welder generator series is designed for professionals who need dependable welding performance and clean auxiliary power in a single, compact machine. Whether you’re in construction, agriculture, or equipment repair, these units deliver powerful DC welding output alongside 120V AC electricity for tools and lighting. Lightweight, portable, and built with Multiquip’s commitment to durability, they’re a smart solution for job sites where flexibility and reliability matter most.

Efficient Dual-Function Performance

At the core of every gas welder generator from Multiquip is a high-performance Honda engine. These rugged engines provide smooth, fuel-efficient operation, perfect for field work or remote applications. The GAW135H and GAW180HEA models offer 135 amps and 180 amps of DC welding power, respectively, with up to 3kW of AC output available for running power tools or jobsite accessories.

This combination means you can strike an arc and run a grinder or charger at the same time, eliminating the need for separate machines. It’s a true portable welder generator designed to save space, time, and fuel on every job.

Compact, Mobile, and Built to Last

These gas powered welder generators are built into tough steel frames with top-mounted handles and lift points for easy transport. Weighing under 200 pounds, both models are light enough for two-person loading and compact enough to fit in a pickup bed or service truck. This makes them ideal mobile generator units for welding tasks in the field, along roadsides, or on remote property where power access is limited.

Whether you need a rugged tool for quick fixes or a steady workhorse for repetitive tasks, Multiquip’s small generators with welding capabilities are ready to perform.
