OVERVIEW

Keep Your Magnum PRO Gun Running Cool

Maximize the performance of your welding operations with the Lincoln Electric KP2743-1-62F-B25 Magnum PRO Nozzle pack. These 550A-rated gas nozzles are the frontline defense for your MIG gun, designed to channel shielding gas effectively while withstanding the intense heat of heavy-duty welding. Sold in a convenient 25-pack, this product is tailored for professional welding shops that demand reliability, consistency, and value in their consumables.

Built for High Amperage

When welding at higher amperages, heat buildup is the enemy of consumable life. The Magnum PRO line is engineered with superior heat dissipation properties. These nozzles feature a substantial wall thickness and high-grade material composition that resists melting and deformation even when pushed to the 550-amp limit. This durability translates to less downtime for nozzle changes and more arc-on time for your welders.

The Flush Tip Advantage

Visibility is key to producing quality welds. The flush tip design of the KP2743-1-62F places the nozzle exit on the same plane as the contact tip. This configuration is ideal for applications where the welder needs to get close to the work or requires a clear line of sight to the puddle. It effectively reduces the accumulation of spatter inside the nozzle bore compared to recessed tips, making cleaning easier and ensuring uninterrupted gas flow. The 5/8-inch bore provides a wide umbrella of shielding gas, protecting the molten pool from atmospheric contamination.

Reliable Thread-On Fit

A loose nozzle can ruin a weld by allowing air to be aspirated into the gas stream. These Lincoln nozzles feature precision-machined threads that lock the nozzle firmly onto the diffuser. This mechanical connection guarantees that the nozzle stays put, even during aggressive manipulation of the gun or when clearing spatter. The thread-on design also facilitates quick and easy replacement, allowing welders to get back to work in seconds.

Industrial Bulk Packaging

For fabrication centers and manufacturing plants, inventory management is crucial. The 25-count bulk pack (B25) ensures you have a steady supply of critical consumables, reducing administrative overhead and unit costs. Equip your team with the best tools for the job with genuine Lincoln Electric Magnum PRO nozzles.

FAQ

These nozzles are designed specifically for Lincoln Electric Magnum PRO Semi-Automatic welding guns rated for high amperage.

The nozzle has a 5/8 inch (15.9 mm) inner diameter, which is a standard size for general to heavy-duty welding.

This is a thread-on nozzle, which ensures a secure connection to the gas diffuser and better heat transfer.

This nozzle is rated for up to 550 Amps, making it suitable for high-heat, heavy-duty applications.

This is a bulk package containing 25 individual nozzles.

Flush means the end of the nozzle is even with the end of the contact tip, offering better visibility and suitability for shorter stick-out welding.

While physically possible, gas nozzles are primarily for gas-shielded processes (MIG/MAG). Flux-cored welding often uses a thread protector instead, unless it is gas-shielded flux core.

They are designed to work with the standard Magnum PRO front-end parts, including the specific diffuser and insulator setup for that gun series.
