Welding You Can Rely On With The Lincoln 140C Mig Welder

One of the most relied upon processes in the heavy industry is MIG welding. Metal Inert Gas welding was once an “exotic” technique that was hard to implement because it was an elaborate, complex operation. Years of refinement have made this process much more accessible. It’s a good thing too, because MIG welding, when properly used, is one of the most versatile forms of welding, and has a great many applications in the modern heavy industry that allow people to do more, with better, faster results. Now, those decades of innovation with MIG welding technology have made the process not just easier to use, but cheaper as well. What was once a process that was only practical for big companies with large operating budgets is now accessible to small companies, and even hobbyists or enthusiasts that want professional results without professional prices. And Lincoln’s got just the thing.

The Lincoln Heritage

For over a century, Lincoln Electric has been a vital part of the American industrial scene, working with the biggest companies on the biggest projects. At the same time, they’ve been working closely with the tradesmen right in the trenches who actually have to do these challenging jobs, and that relationship between the goals of management and actual working conditions of the tradesmen has been very fruitful for Lincoln’s designers. The result has been constant innovation in tools to help people to work faster, more efficiently and, above all, with more safety and comfort, but without compromising on quality. This has led to better, cheaper technology, new advances, and taking what was once expensive processes only for top tier companies and making the tools accessible enough that anyone that wants to use them can benefit.

Affordable Quality With the Portable Power MIG 140C

The Lincoln K2471-2 Power MIG 140C Welder is an entry level model designed to keep pricing low while still allowing people in smaller shops, or working at home, the farm or ranch to enjoy a high-quality welder. This little welder is incredibly durable thanks to the toughest PC board protection in the industry, which has been “potted” to seal sensitive components against the environment, with “trayed” plastic for rigidity and shock resistance. In terms of performance, the 140C has an industrial cast aluminum drive with split wire guides and brass-to-brass gun connection. It’s also quite versatile, able to accept a spool gun as well as a standard MIG gun. For ease of use the Diamond Core technology makes for an extremely forgiving arc, with low spatter, a wide voltage sweet spot, and a no hassle, “tool-less” design for input power changes, wire spool mounting, and polarity changes. This is easy but powerful to use, though it’s still affordable.
