621-0065 - MK Products 400A Water Cooled Gas Cup for EZ-Lock Barrels

Keep Your Arc Cool and Stable

When you are pushing 400 amps through a MIG gun, things get hot fast. The MK Products 621-0065 Gas Cup is built to handle the heat. This isn't just a standard nozzle; it is a fully water-cooled gas cup designed for the heavy hitters in the welding industry. If you are running an MK Products push-pull gun with an EZ-Lock barrel, this is the replacement cup you need to keep your production line moving. It is compatible with the entire range of EZ-Lock barrels, including straight, 45-degree, and 60-degree angles, giving you the versatility to tackle any joint configuration without changing your entire setup.

Water cooling is a game-changer for consumable life. By circulating coolant right up to the nozzle, the 621-0065 prevents spatter adhesion and reduces the rate at which the nozzle degrades. For welders working with aluminum, this is especially important because a hot nozzle can lead to erratic gas coverage and soot buildup. This cup stays cooler longer, helping you lay down clean, shiny beads shift after shift. The robust construction resists the mechanical abuse of industrial environments, while the precise bore ensures that your shielding gas—whether Argon or a mix—is directed exactly where it needs to go.

Changing out consumables shouldn't be a wrestling match. The design of this cup works perfectly with the EZ-Lock system, allowing for fast removal and installation. This means less time fiddling with your torch and more time burning wire. Whether you are repairing a boat hull or fabricating heavy transport equipment, reliability is key. Don't let a worn-out or overheated nozzle compromise your weld quality.

Key Benefits:

• High Amperage Rating: Handles up to 400 amps, perfect for thick plate welding.
• Versatile Fit: Works with all EZ-Lock barrel geometries.
