Tweco 1110-1142 Mig Contact Tip 0.035 Inch

Product Description

The TWECO 1110-1142 is a threaded MIG contact tip machined from copper alloy tubing for consistent electrical conductivity and smooth wire feed. Sized for 0.035-inch wire diameter, the tip maintains an inside diameter tolerance of plus or minus 0.003 inches, ensuring reliable arc stability and consistent contact with the gas diffuser. Each tip is individually marked with the part number and wire diameter for quick identification on the job. Welding technicians and fabricators install this tip as a routine consumable in MIG welding guns.

This contact tip is suited for MIG welding applications in light industrial, fabrication shop, and maintenance welding environments. It is designed for use with 0.035-inch solid or flux-core wire feeds. The threaded mounting style ensures secure seating against the gas diffuser, maintaining proper shielding gas flow and stable wire-to-contact engagement during welding. Sold in minimum quantities of 25, it is well-suited for shops that cycle through contact tips regularly.

Key Features

• Machined from copper alloy tubing for excellent electrical conductivity and a smooth internal bore
• Inside diameter held to plus or minus 0.003 inches for consistent wire guidance
• Threaded style ensures positive contact with the gas diffuser when installed on the MIG gun
• Each tip is marked with part number and wire diameter for fast field identification
• Designed for 0.035-inch wire diameter MIG welding applications

Compatibility

Designed as an OEM-style replacement contact tip for MIG welding guns accepting threaded-style tips for 0.035-inch wire diameter.

Installation Notes

Contact tips are installed and serviced by welding technicians as standard consumable maintenance on MIG guns. Always power down the welding machine and allow the gun to cool before replacing a contact tip. Use the appropriate wrench or tip tool to thread the tip firmly into the gas diffuser without overtightening, which can distort the bore. Inspect the diffuser and liner condition when replacing the contact tip to maintain consistent wire feed performance.
