Tweco 1160-1425 Contact Tip 0.035 Inch Mig Welding

Product Description

The TWECO 1160-1425 is a standard contact tip designed for MIG welding guns, serving as the final electrical transfer point between the welding wire and the weld puddle. Machined from copper alloy tubing, it delivers consistent current transfer and maintains a smooth inside diameter surface for reliable wire feed. The inside diameter tolerance is held to plus or minus 0.003 inches, ensuring repeatable performance across high-cycle production environments. This tip is rated for heavy-duty welding applications up to 200 amperes and is designed for use with a threaded-style gas diffuser on compatible MIG gun series. It measures 1.1 inches in length and fits 0.035-inch wire diameter.

This contact tip is suited for professional MIG welding in both fabrication shops and field applications. The threaded design ensures proper seating against the gas diffuser when installed to the MIG gun, maintaining consistent shielding gas flow and arc stability. Each tip is individually marked with the part number and wire diameter for fast identification during tip changes on the gun. Sold in minimum quantities of 25, this tip is a standard consumable for welding professionals running 0.035-inch wire on TWECO-compatible MIG guns up to 200 amperes.

Key Features

Compatibility

Designed as an OEM-style replacement contact tip for TWECO MIG gun series using threaded or Eliminator style gas diffusers with 0.035-inch wire diameter.

Installation Notes

Contact tips are installed and replaced by qualified welding technicians or maintenance personnel. Always power down the MIG welder and allow the gun to cool before removing or installing a contact tip. Use the appropriate tip wrench to thread the tip fully into the gas diffuser — hand-tight plus a firm snug turn is typical practice. Inspect the gas diffuser and nozzle for spatter buildup each time a tip is changed to maintain shielding gas coverage.
