Recommended Applications
  • Spray-arc MIG welding on steel: Ideal for high-deposition spray-transfer welding on plate, structural steel, and heavy-gauge fabrication using 0.035" solid wire.
  • Stainless steel fabrication: Delivers reliable current transfer for spray welding of 304 and 316 stainless steel when using ER308L or ER316L wire at 0.035".
  • Production and automated welding: Suitable for semi-automatic and automated MIG applications where consistent tip-to-wire contact is critical for arc stability.
  • High-amperage continuous welds: Designed for sustained spray-arc duty cycles on MK Products guns operating at elevated current levels.
Compatibility / What It Fits

The 621-0391-10 contact tip is an OEM MK Products part designed for the Cobra and Python gun families, including spray-transfer models that accept the standard MK threaded tip configuration. Always verify your gun's tip thread pattern before ordering; MK spray tips are not interchangeable with non-MK gun bodies.

Wire size compatibility: 0.035" solid wire only. Do not use with 0.030" or 0.045" wire — incorrect tip bore reduces contact precision and accelerates wear.
