Contact Tip, Fastip .312" OD .030-.035" AL Wire | MIL206186

The Miller Electric 206186 FasTip Contact Tip features a .312" (5/16") Outside Diameter and is precision-bored with a .041" (1.0 mm) internal diameter. This specific bore size is optimized to handle the thermal expansion of .030" (0.8 mm) aluminum wire, preventing the wire from seizing or dragging during high-heat cycles. Additionally, it is rated for use with .035" (0.9 mm) hard wires (steel/stainless), providing a versatile solution for shops that switch between materials.

• Dual-Wire Compatibility: Optimized for .030" aluminum wire and .035" steel/hard wires, reducing the number of different consumables you need to stock.
• FasTip™ Quick-Lock Design: Engineered for a secure electrical connection and tool-free replacement, allowing you to swap tips in seconds and get back to welding.
• Superior Heat Dissipation: Constructed from high-quality copper to manage extreme temperatures, which significantly reduces burn-back and extends the tip's service life.
• Precision Smooth Bore: The internal bore is polished to minimize friction, ensuring smooth wire feeding and a consistent arc for high-quality weld beads.
• Industrial Strength: Rated for heavy-duty applications (up to 400A depending on the gun), making it ideal for structural fabrication and marine repair.
