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.

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.
