MK Products 0.035 Spray Arc Contact Tip (Pack of 10)

Genuine MK Consumables for Aluminum MIG Welding

Keep your MK Cobra, Python, or Prince welding gun performing at its peak with the MK Products 621-0001-10 Contact Tips. Designed specifically for welders running .035" wire in Spray Arc mode, these tips are a must-have for serious aluminum fabrication. Aluminum welding presents unique challenges, including wire softness and high thermal expansion. These tips address those issues with a carefully calculated 0.044" inner diameter. This specific ID prevents the wire from dragging or sticking inside the tip as it heats up, a common issue that leads to frustrating feed problems and downtime.

MK Products is renowned for their push-pull technology, and their consumables are built to the same exacting standards. The 1/4-20 thread design allows for quick changeovers and a tight fit that maximizes current transfer to the wire. Consistent current transfer is the key to a smooth, spatter-free spray arc. Whether you are fabricating boat hulls, trailers, or aerospace components, using the correct "Spray Arc" designated tip ensures your welds are clean and your wire feed is consistent.

Don't compromise your weld quality with generic tips that may not have the correct metallurgy or bore precision. This 10-pack provides excellent value and ensures you are ready for the next job. Compatible with most standard MK goosenecks and barrel assemblies, these tips are the professional's choice for reliable aluminum wire feeding.
