Tweco Style 11 Series MIG Welding Contact Tips 25pk | M6 Thread

The Tweco style 11 series MIG welding contact tip is a direct replacement for Tweco #1 and Mini-Mig welding guns. Machined from high-conductivity copper, these contact tips deliver consistent arc performance and extended tip life — even on high-duty-cycle applications.

Compatible with most 110V MIG welders and popular off-brand machines, the 11 series is the go-to contact tip for hobbyists and professionals alike. Available in multiple wire diameter sizes — the number after "11" indicates the wire size (e.g., 11-30 = .030" wire). Tip: When MIG welding aluminum wire, size up one tip diameter for smoother feeding.

Specifications:

• Length: 1"
• Thread: M6-1
• Diameter at weld surface: 1/4"
• Sold in packs of 25

Compatible with: Tweco #1, Mini-Mig, and most 110V MIG welding guns except Miller style.
