The MK Products 3/64" Spray Contact Tip - 621-0393-10 is a specialized welding component designed for precision spray arc welding applications, particularly for aluminum wire. This package contains 10 contact tips, each engineered to accommodate 3/64" (1.2 mm) aluminum welding wire, making them ideal for a variety of spray transfer welding processes. With a length of 1.57" and a diameter of 3/8", these tips offer optimal performance and durability in spray arc welding processes.
Crafted from durable materials, these contact tips feature an inner diameter (ID) of 0.060", precisely machined to ensure consistent wire feeding and excellent electrical conductivity, crucial for maintaining a stable arc and producing high-quality welds. The spray arc designation indicates their suitability for high-amperage, high-deposition welding applications, particularly beneficial for aluminum welding. Compatible with a wide range of MK Products MIG gun models including CobraMAX, Cobra MX-HD, Cobra X-HD, Python, Python LX, Python X, Prince X, Prince XL, and Prince XL Spool Gun, these tips offer versatility across various welding setups. The 10-pack format provides convenience and value for professional welders, ensuring a ready supply of replacement tips to minimize downtime and maintain consistent welding performance.
Engineered to exacting specifications, these premium contact tips are constructed from copper alloy with advanced heat resistance properties, allowing them to withstand the high temperatures and electrical currents associated with spray arc welding. The precision manufacturing process ensures consistent dimensional accuracy across all tips in the package, delivering reliable wire feeding and arc stability even during extended welding sessions. The enhanced durability of these specialized tips makes them particularly valuable for production environments where throughput and quality are paramount considerations.
