Tweco 1110-1244 Mig Contact Tip 0.045 Inch

Product Description

The TWECO 1110-1244 is a heavy duty MIG welding contact tip machined from copper alloy tubing. It delivers consistent current transfer to the welding wire by maintaining a smooth, uniform inside diameter along its full length. The inside diameter tolerance is held to plus or minus 0.003 inches, ensuring reliable wire feed and stable arc performance. This contact tip uses a threaded style design that seats securely into a gas diffuser when installed on a MIG gun. Welding professionals and fabricators rely on this level of dimensional consistency to reduce wire sticking and minimize downtime during production welding operations.

The TWECO 1110-1244 is designed for use with 0.045 inch welding wire in MIG and wire-feed welding applications. It is suited for both shop and field use across light manufacturing, fabrication, and maintenance welding. Each tip is individually marked with the part number and wire diameter, making it easy to identify and organize in multi-wire-size environments. This tip fits MIG guns that accept a threaded contact tip into a compatible gas diffuser assembly.

Key Features

• Machined from copper alloy tubing for excellent electrical conductivity and heat dissipation
• Inside diameter tolerance held to plus or minus 0.003 inches for consistent wire guidance
• Threaded style design ensures secure seating in a compatible gas diffuser
• Each tip is marked with part number and wire diameter for easy identification
• Heavy duty construction rated for 0.045 inch wire diameter

Compatibility

Designed as an OEM-style threaded contact tip replacement for MIG guns that accept a threaded tip into a gas diffuser assembly and are compatible with 0.045 inch welding wire.

Installation Notes

Contact tips are installed and serviced by welders and welding equipment technicians. Always power down the welding machine and allow the gun to cool before replacing a contact tip. Thread the tip in by hand first to avoid cross-threading, then snug with an appropriate wrench — do not overtighten, as this can distort the tip or damage the diffuser threads. Inspect the gas diffuser for wear or spatter buildup before installing a new tip.
