Lincoln Electric KH831 Mig Welder Tips Insulators 5 Pack

Product Description

The LINCOLN ELECTRIC KH831 is a pack of five MIG welder contact tips and insulators designed for use with small-diameter wire. These replacement consumables fit into the front-end assembly of a MIG gun, where the contact tip transfers welding current to the wire and the insulator electrically isolates the tip from the nozzle. Rated for wire up to 0.025 inches in outside diameter, this pack is suited for light-gauge MIG welding applications. Installers and welding technicians who perform frequent tip changes will appreciate the five-piece quantity for keeping spares on hand. The pack weighs 0.5 pounds and is a direct OEM-style replacement consumable.

These contact tips and insulators are intended for MIG welding setups running fine wire, typically used on thin sheet metal, auto body repair, light fabrication, and similar applications where 0.025 inch wire is specified. They are appropriate for both shop and field use by welding professionals and experienced technicians who maintain MIG guns regularly. Sourced directly from LINCOLN ELECTRIC as a replacement consumable, the KH831 fits into the standard service cycle for guns requiring periodic front-end consumable replacement.

Compatibility

Designed as an OEM-style replacement consumable for MIG welding guns requiring 0.025 inch contact tips and insulators. Consult your MIG gun documentation to confirm front-end fitment before installation.

Installation Notes

Contact tip and insulator replacement is a routine maintenance task performed by welding technicians. Always power down the welder and allow the gun to cool before handling front-end consumables. Thread the contact tip in by hand first, then snug with appropriate pliers — do not overtighten, as this can distort the tip bore. Inspect the nozzle and diffuser for spatter buildup at each tip change to extend consumable service life.
