120 Amp Engine Driven Welder Generator 2200 Watt 7 HP Gas Powered


Description

The Tomahawk TWG120A is a rugged, gas-powered welder generator built for professionals, farmers, ranchers, and serious DIYers who need reliable welding power and electrical output wherever the job takes them. Powered by a 7 HP Tomahawk engine with 208cc displacement, it delivers up to 120 Amps of DC output with a 60% duty cycle - capable of handling 6010 through 6013 welding rods and material thicknesses up to 3/8 inch. The Permanent Magnetized Generator (PMG) inverter design produces a stable sine wave, ensuring consistent, clean power for both welding and running electric tools simultaneously.

Whether you're repairing fencing on a remote ranch, tackling structural work on a job site, or keeping a workshop running during an outage, this machine handles it all without flinching. The 8-inch never-go-flat wheels and ergonomic handles make it genuinely portable, and the 2-year engine warranty backs up the durability you can see and feel.

FAQ

Can I weld and run power tools at the same time?

Yes - the TWG120A is specifically designed to weld and power electric tools simultaneously. The PMG inverter generator produces up to 2000 rated watts of clean AC power through its two 120V outlets, so you can keep tools running while you weld without sacrificing performance on either end.

What welding rods is this machine compatible with?

The TWG120A is compatible with 6010 through 6013 welding rods and can weld material thicknesses of 1/3, 1/4, and 3/8 inch. It supports Arc, Stick, and MMA welding processes, making it suitable for a wide range of structural and repair applications.

Very portable for a machine of its capability. It comes with an 8-inch never-go-flat wheel kit and handles that make it easy to move across job sites, farms, or rough terrain. At 99 lbs., it is designed to be relocated by one or two people and fits in the bed of a pickup truck.

Does this unit require a lot of fuel?

The TWG120A features Automatic Idle Control, which reduces engine speed - and fuel consumption - when welding demand is low. The 1.6-gallon fuel tank is sized for extended field use, and the idle control feature helps stretch your runtime between refuels during typical work sessions.

What warranty does the Tomahawk TWG120A come with?

The TWG120A is backed by a 2-year engine warranty from Tomahawk Power. For warranty service or support, contact Tomahawk Power directly. The machine also comes with a 30-day money-back guarantee for purchases within the continental United States, subject to the product being unused and in original packaging.

Is this welder generator suitable for emergency backup power?

Yes - in addition to welding, the TWG120A can serve as a backup power source for critical tools, basic lighting, and urgent repairs during outages. Its two 120V AC outlets and 2000 rated watts of output make it a practical emergency power solution for farms, job sites, and workshops.
