NICETECH, Gasless Flux Cored Welding Wire, Carbon Steel, E71TGS. 030-Diameter, 10 Pounds Spool, Silver, Package of 1

E71T-GS is a self-shielding flux cored welding wire designed to weld carbon steel. The benefit of using this product is that it does not require external shielding gas. This product has advantage of high strength, high molding efficiency, little welding spatter etc. The product may be used for outdoor, high-altitude, and other different operating environments. All positions and angles of welding can apply to this product. This product is also suitable for low-alloy steel welding and galvanized structural parts welding. This wire is widely used in construction for street guardrails, doors, windows, shipbuilding, mechanical manufacture, pressure vessels, boilers, etc. Using this welding wire is more efficient than using traditional welding electrode as continuous welding could apply to this welding wire, and therefore increases the productivity and reduces total electricity consumption. Power polarity: DC (-) DC positive connection (Connect ground wire to the negative electrode +, and the welding torch to the positive electrode -).
