KP21T-62 - Lincoln Electric KP21T-62 Fixed Gas Nozzle .625 ID for Magnum 100L

Upgrade Your Magnum 100L with the KP21T-62 Nozzle

If you are welding with a Lincoln Electric Magnum 100L gun, the KP21T-62 Fixed Gas Nozzle is the standard for reliability and ease of use. Welding can be a variable process, but your equipment setup shouldn't be. This nozzle features a fixed recess design, meaning when you install it, your contact tip sits at the exact depth Lincoln engineers intended. This eliminates the guesswork of adjusting a slip-on nozzle and ensures you have the correct stick-out every time you pull the trigger.

The 0.625-inch (5/8") bore is the sweet spot for general-purpose MIG welding. It provides a wide enough umbrella of shielding gas to protect your weld pool even if you are moving a bit fast or dealing with minor drafts, yet it is narrow enough to get into tighter joints compared to larger industrial nozzles. Whether you are working on automotive body panels, light fabrication, or home repairs, this nozzle helps keep your welds clean and free of porosity.

Durability is key in any shop. The KP21T-62 is made from heavy-duty copper that resists heat buildup and allows spatter to be cleaned out relatively easily. To extend the life of your nozzle, we recommend using a pair of welding pliers to clean out spatter regularly and applying a nozzle gel or anti-spatter spray. When the nozzle edge becomes too ragged or the spatter buildup restricts flow, swapping in a fresh KP21T-62 will restore your gun's performance instantly.

Why Choose Genuine Lincoln Parts?

Using genuine Lincoln Electric consumables ensures that your Magnum gun operates as designed. The threads and fitment are precise, preventing gas leaks at the diffuser which can lead to poor weld quality. Keep a few of these in your toolbox so you are never caught with a clogged nozzle in the middle of a project.
