    • top notch
This Miller welder is phenomenal. Super easy to set up, runs smooth, and the welds come out clean every time. The Auto-Set feature makes dialing in settings effortless, even for different materials, and it saves a ton of time. Plenty of power for my projects, and it feels rock-solid and reliable. I’ve used other welders before, but this one is on another level — professional quality, simple controls, and built tough. Absolutely worth the investment. Highly recommend! ... show more

    • Smooth operation
This has been the smoothest welder I've used. Plus it works great off the Ford Lightning tailgate power.
