The LINCOLN ELECTRIC KH833 is a replacement contact tip and nozzle insulator kit designed for MIG welding guns. This 5-piece pack supplies the consumable components that protect the nozzle body from spatter buildup and guide the wire electrode through the contact tip at the weld point. Sized for 0.035-inch wire, these parts maintain consistent electrical contact and arc stability during the weld. Welding technicians and fabricators install these as routine consumable replacements to keep MIG guns operating cleanly and efficiently.
This kit is suited for light-to-medium MIG welding applications in fabrication shops, manufacturing facilities, and field repair work. The 0.035-inch maximum wire diameter rating covers a common wire size used in both flux-core and solid-wire MIG processes on mild steel, stainless, and similar base metals. The 5-piece quantity supports multiple tip changes across a work shift or a single machine service.
Designed as an OEM-style replacement consumable for LINCOLN ELECTRIC MIG welding guns accepting 0.035-inch contact tips and compatible nozzle insulators. Verify gun model and tip thread specification before installation.
Contact tips and nozzle insulators are installed by qualified welding technicians as part of routine gun maintenance. Power down and disconnect the welding machine from its power source before changing consumables. Allow the nozzle and tip to cool completely before handling to avoid burns. Inspect the diffuser and nozzle body for damage or excessive spatter buildup when replacing tips.
