The Powerbuilt 125 AMP Inverter Flux-Core Wire Feed Welder offers all the benefits of IGBT inverter technology in a lightweight portable gasless welder. Novice and experienced welders alike will lay down beautiful beads thanks to the consistent heat and flow of DC power, stepless adjustable wire feed and voltage.It's easy to experiment and fine-tune your welding, with 2 simple and intuitive controls to adjust as needed for great results. And you'll be able to use it anywhere with 120V household current.The DC current generates more consistent heat and flow than AC welders to produce smoother, stronger welds. And at just 20 pounds all-in, this compact little welder is easy to carry and store.With a 40% duty cycle at 90 amps, this little workhorse will have no trouble keeping pace with light to medium duty welding. We put it through a 120-hour lifecycle test at 90 Amps constant with zero failures. And it runs so cool, we couldn't trip the thermal overload protection no matter how hard we tried. Everything you need to start welding is included. Just attach the ground clamp, select your voltage and wire feed speed and start welding with the heavy-duty flux core gun!You can weld everything from thin gauge steel up to 1/4-inch thick steel plate using 0.030 or 0.035 flux core wire. It’s perfect for the hobby and professional welder.Use it for hobby, yard art, auto body, exhaust systems, fencing, mini bikes, go carts, trailers, lawn and garden equipment and more.
