Tweco 7050-1002 Mig Contact Tip 0.035 in 11 Series

Product Description

The TWECO 7050-1002 is a standard duty MIG contact tip from the Tweco 11 Series, designed to guide 0.035-inch wire with consistent electrical transfer at the point of welding. Machined from extruded or gun-drilled copper alloy tubing, the tip delivers a smooth, consistent bore with an inside diameter tolerance held to plus or minus 0.003 inches. At 1 inch in length and 0.25 inches in outside diameter, it is a compact, threaded-style tip rated for standard welding applications up to 200 amps. Each tip is individually marked with the part number and wire diameter for fast identification in the field.

This contact tip is designed for use in standard MIG welding applications in both shop and field environments. It installs into a threaded gas diffuser to maintain proper electrical contact during welding. The 7050-1002 is compatible with the Tweco Spray Master (160 to 250 A), the Tweco mini-MIG gun, and the Tweco No. 1 MIG gun series. It is suitable for light to moderate duty production welding, maintenance and repair work, and fabrication shops running wire in the 0.035-inch range.

Installation Notes

Contact tip installation and replacement is performed by a qualified welding technician or maintenance professional. Power down and disconnect the MIG gun from the welder before servicing consumables. Thread the tip into the gas diffuser by hand until snug, then tighten with the appropriate tip wrench — do not overtighten, as this can distort the bore or damage the diffuser threads. Inspect the bore for wear or spatter buildup at regular intervals and replace when wire feed becomes inconsistent or arc quality degrades.
