K2622-2 - Lincoln Electric Precision TIG 375 AC/DC TIG/Stick Welder K2622-2

Master the Arc with the Lincoln Precision TIG 375

Take your welding to the next level with the Lincoln Electric Precision TIG 375, a machine that perfectly balances simplicity with advanced technological control. Whether you are an automotive restorer, a pipe welder, or a fabrication artist, the K2622-2 gives you the confidence to tackle any job. At the heart of this welder is Lincoln's Micro-Start II Technology, which provides an incredibly stable arc at low amperages. This means you can weld razor-thin materials without fear of burn-through or wandering arcs, giving you precise control over crater fills and bead starts.

When it comes to aluminum, the Precision TIG 375 is a game-changer. The AC Auto Balance feature takes the guesswork out of setting your cleaning versus penetration ratio. It automatically calculates the optimal balance for the best weld quality, letting you focus on your puddle manipulation. For those who prefer total control, you can manually adjust the AC Balance to increase cleaning action for dirty oxides or increase penetration for thicker sections. This flexibility ensures that you get the perfect bead profile every time, regardless of the base material condition.

Power to Spare

Don't let the "Precision" name fool you; this machine is a beast when it comes to power. With a top-end output of 420 amps, you have the headroom to weld thick plate and heavy castings that smaller machines simply can't touch. The wide amperage range of 2 to 420 amps means this single machine can replace multiple units in your shop, handling the finest detail work and the heaviest structural repairs with equal competence. The built-in TIG pulser is another standard feature that elevates your work, helping you control heat input to prevent warping on sheet metal projects.

Designed for the Welder

Lincoln Electric understands that a cluttered workspace hinders productivity. That's why the Precision TIG 375 features smart design elements like a side-mounted torch holder and integrated cable management. These features keep your leads organized and your torch safe between welds. Additionally, the machine's Fan-As-Needed (F.A.N.) system reduces noise and lowers power consumption by only running the cooling fan when the system requires it. This creates a quieter, more pleasant shop environment, allowing you to focus entirely on laying down the perfect weld.
