8-6515 - Tweco 8-6515 Handle End Cap for No. 6 MIG Guns

Genuine Replacement End Cap for Tweco No. 6 Series

The Tweco 8-6515 End Cap is a critical replacement component designed specifically for the heavy-duty Tweco No. 6 series MIG guns, including models 6A and 6B. As an Original Equipment Manufacturer (OEM) part, it guarantees precise compatibility with the handle assembly of these 600-amp welding guns. The end cap serves a vital structural role, securing the rear portion of the handle where the cable assembly enters the gun. By maintaining a tight seal and rigid structure, it prevents the ingress of workshop debris, metal dust, and spatter into the sensitive connection areas of the torch.

Manufactured from high-grade, impact-resistant composite materials, this end cap is engineered to withstand the rigorous demands of industrial welding environments. It is resistant to the high heat typically generated during high-amperage welding applications and provides excellent durability against drops and impacts. The part is clearly marked "STD" (Standard), allowing for quick identification in maintenance inventories. Replacing a damaged or cracked end cap is essential for operator safety and equipment longevity, as a compromised handle can lead to loose connections or exposed cabling.

Maintenance personnel and tool crib managers can rely on the 8-6515 to restore Tweco No. 6 guns to factory specifications. Its installation is straightforward, fitting seamlessly with the existing handle halves and hardware of the 6A and 6B models. By utilizing genuine Tweco parts, users ensure that the ergonomic balance and electrical safety of the welding gun are maintained, minimizing downtime and repair frequency in high-volume fabrication settings.
