Tweco 1320-1100 Nozzle Insulator 250A Mig Gun

Product Description

The TWECO 1320-1100 is a slip-on nozzle insulator designed for use with Tweco-style MIG welding guns rated up to 250 amps. This insulator fits between the nozzle and the gas diffuser, providing electrical isolation and heat resistance during MIG welding operations. It is a direct consumable replacement used by welding professionals and maintenance technicians to keep MIG guns operating safely and efficiently. At 0.9 inches wide and 0.7 inches in both length and height, the part is compact and lightweight at 0.01 pounds, making it straightforward to keep on hand as a service consumable.

This insulator is suited for production welding environments, fabrication shops, and maintenance applications where Tweco-style MIG consumables are in regular use. It is sold in minimum quantities of 25 per order, which aligns with typical shop restocking practice for high-turnover consumables. The slip-on design allows for fast nozzle changes without special tooling, reducing downtime during active welding jobs.

Compatible with Tweco No. 2 MIG guns rated up to 250 amps. Designed as a Tweco-style slip-on nozzle insulator replacement for standard Tweco-pattern MIG gun assemblies.

Installation Notes

Installation is performed by welding technicians as part of routine MIG gun consumable maintenance. Before replacing the insulator, disconnect the welding machine from its power source and allow the gun to cool completely. The slip-on insulator seats over the diffuser body before the nozzle is attached — inspect the diffuser and contact tip for wear before reassembling. Follow the equipment manufacturer's consumable replacement sequence to ensure proper electrical isolation.
