Tweco 1340-1125 Nozzle Insulator 5 Pack Mig Gun

Product Description

The TWECO 1340-1125 is a nozzle insulator designed for MIG welding guns in the Weldskill product line. This insulator fits between the nozzle and the gun body, shielding the contact tip area from spatter and heat to extend the service life of the gun and maintain consistent weld quality. Sold in a pack of 5, it is a consumable replacement part that welding professionals keep on hand to minimize downtime during active welding operations. The compact form factor — 1.1 inches wide and 0.8 inches in both length and height — ensures a precise, low-profile fit within the nozzle assembly.

The 1340-1125 insulator is suited for use with Tweco Weldskill MIG guns, specifically the WS34A model. It is a standard replacement consumable in light-to-medium duty MIG welding applications found in fabrication shops, maintenance and repair operations, and production welding environments. Welding technicians and shop personnel performing routine gun maintenance will replace these insulators as part of a standard consumable rotation alongside contact tips and nozzles.
