  • Heavy-duty copper construction withstands demanding MIG welding tasks
  • 5/8 inch bore diameter suits high-amperage applications
  • Threaded connection ensures secure fit on compatible guns
  • 1/8 inch tip recess optimises gas coverage and wire stick-out
  • Compatible with Centerfire, BTB and S-Gun series consumables

Threaded Copper Nozzle Cone

This Bernard Q3015AE8EMC nozzle cone fits Centerfire and BTB MIG guns with a threaded 3/8 inch connection. The copper construction handles heavy-duty welding cycles and positions the contact tip at a 1/8 inch recess. It works with the D-1 gas diffuser and Centerfire contact tip series for consistent gas coverage. The part replaces manufacturer numbers including 3015 and 4015 variants.

MIG welders using Centerfire or BTB guns

Suits operators running standard MIG (GMAW) processes who need a durable copper nozzle with a threaded fit. Not for welders using slip-on nozzle systems or guns that require a different bore size, tip recess or diffuser style. Buyers without a D-1 diffuser or Centerfire tips should look elsewhere.

5/8 inch bore with 1/8 inch tip recess

The 5/8 inch bore diameter and fixed 1/8 inch tip recess determine gas flow dynamics and wire stick-out. These dimensions must match the gun and application requirements exactly. Verify both figures against the equipment manual before ordering.

Questions about this item

How do I install the threaded nozzle cone onto my Centerfire MIG gun, and what step do people often miss?

Screw the cone onto the D-1 gas diffuser until it seats firmly; the step many miss is confirming the 1/8 in tip recess so the contact tip sits flush before welding.

What maintenance or replacement will this copper nozzle cone need over time?

Replace the cone when spatter buildup narrows the 5/8 in bore or when the threaded connection strips, typically after heavy MIG welding cycles.

What limit appears first during sustained MIG welding with this heavy-duty nozzle?

The copper bore absorbs heat until spatter adheres and restricts gas flow, so the 5/8 in opening clogs before the threads fail.
