OVERVIEW

Reliable Performance for Magnum MIG Guns

Maximize the performance of your Lincoln Electric Magnum MIG gun with the KP14A-364 Contact Tip, specifically tailored for 3/64-inch (1.2 mm) aluminum welding wire. In the world of MIG welding, the contact tip is the final point of electrical transfer before the arc is struck. For aluminum applications, the margin for error is slim. Aluminum wire is softer and expands more when heated than steel wire; using a standard tip can cause friction, erratic feeding, and micro-arcing inside the bore. The KP14A-364 addresses these challenges with a slightly oversized ID and smooth finish, allowing the wire to glide freely while maintaining sufficient electrical contact.

This 10-pack of contact tips is designed for use with the classic Magnum 200, 300, and 400 amperage guns. These guns are staples in fabrication shops across the world, known for their ruggedness and comfort. By pairing your Magnum gun with the correct "A" series contact tip, you eliminate many of the common headaches associated with aluminum MIG welding, such as bird-nesting at the drive rolls caused by downstream resistance. The copper alloy construction withstands the intense heat of the welding arc, resisting deformation and wear over extended periods of use.

Regular maintenance and consumable replacement are key to high-quality welding. As a contact tip wears, the bore becomes oval-shaped, leading to a wandering arc and poor bead placement. With this bulk pack, you can afford to change your tip the moment performance begins to degrade, ensuring every weld meets your standards. The KP14A-364 is not just a spare part; it is a critical element in the welding circuit that directly influences the quality of your finished product. Trust Lincoln Electric's engineering to keep your aluminum projects running smoothly and efficiently.

FAQ

The KP14A-364 contact tip is designed for use with Lincoln Electric Magnum 200, 300, and 400 series MIG welding guns.

This tip is specifically designed for aluminum wire. The 'A' in the part number (KP14A) typically designates a tip with geometry optimized for aluminum expansion.

This contact tip is sized for 3/64 inch (1.2 mm) welding wire.

This product is sold as a pack of 10 contact tips.

Aluminum wire expands more than steel when heated. Aluminum-specific tips have slightly larger bore tolerances to prevent the wire from binding or seizing inside the tip.

While it is physically possible, it is not recommended. The larger clearance meant for aluminum may cause poor electrical contact and a wandering arc if used with steel wire.

You should replace the tip if the bore becomes oval-shaped (keyholing), if spatter fuses to the tip blocking gas flow, or if you experience erratic arc starts and burn-back.
