—A. The Lincoln Electric 90i is designed for MIG welding (with shielding gas) and flux-cored welding (gasless). It is especially effective for light fabrication, home repairs, hobby welding, and small metalworking jobs. It does not support Stick or TIG welding.
—A. This welder operates on a standard 120V household outlet, making it highly convenient for home users. You don’t need a special industrial power setup, which adds to its user-friendliness and portability.
—A. Yes, the Lincoln 90i is beginner-friendly. It features a simple control interface, and automatic protection systems, and comes ready to use out of the box with minimal setup. It’s an excellent welder for DIY users and those just starting in MIG or flux-core welding.
—A. Yes, the 90i typically includes a MIG gun, work cable, and clamp, a gasless nozzle, a contact tip, a sample spool of flux-cored wire, and a shoulder strap. However, if you plan to do MIG welding with shielding gas, you’ll need to purchase a gas regulator and gas cylinder separately.
—A. Yes, the 90i supports MIG welding with shielding gas. To use this feature, you will need a cylinder of shielding gas (such as C25 for mild steel), a regulator, and a solid MIG wire. The machine includes a gas connection for this purpose.
—A. The Lincoln 90i is compatible with wire diameters ranging from 0.025 to 0.035 inches. It supports both flux-cored and solid MIG wires, giving you flexibility depending on your application and material.
—A. With the appropriate wire and settings, the Lincoln 90i can weld steel up to 1/4 inch thick in a single pass. For thinner materials like sheet metal, it provides fine control for clean, spatter-free welds.
—A. Yes, this welder is designed to be lightweight and portable. It features a protective metal case for durability and a shoulder strap for convenient transport, making it ideal for on-site repair work or mobile jobs.
—A. Yes, the 90i includes a built-in wire feed system that delivers smooth and consistent feeding of both flux-cored and solid MIG wires. The drive system is robust and designed for minimal maintenance.
—A. The Lincoln 90i typically offers a 20% duty cycle at 90 amps, meaning it can weld for 2 minutes out of every 10 at full output before requiring a cooldown. For lower output settings, the duty cycle increases accordingly.
—A. Yes, especially when using flux-cored wire, which doesn’t require shielding gas. This makes it suitable for outdoor welding, where wind might blow away shielding gases used in MIG welding.
—A. Yes, the 90i is designed for quick setup with minimal technical knowledge required. The intuitive controls, quick-change drive roll system, and clear documentation make setup and adjustments fast and hassle-free.
—A. The Lincoln 90i is not specifically designed for aluminum welding. While it may technically weld aluminum with proper wire and shielding gas, the lack of spool gun support and low amperage output limit its effectiveness. It’s better suited for mild and stainless steel.
