  • Product typeWelding Parts & Supplies
  • Standard-duty copper nozzle for reliable MIG welding
  • Tapered 5/8 in bore optimises gas coverage on spool guns
  • Threaded FasTip connection fits Spoolmate and Spoolmatic series
  • Steel construction resists heat and spatter in daily use
  • Compatible with diffuser 199390 for quick changeovers

Compatible welding nozzle for Spoolmate series

This copper-coloured steel nozzle fits Miller Spoolmate 3545 and Spoolmatic 1, 15, 2, 3, 30, XR, XR-15, XR-30 and XR-M spool guns. It uses a threaded connection and a tapered bore of 5/8 in. The part is rated for standard-duty MIG welding with FasTip contact tips.

Threaded connection limits tool-free changes

The threaded attachment requires a wrench for removal, so nozzle swaps take longer than slip-on designs. Standard-duty rating means the nozzle suits typical fabrication work but not continuous high-amperage runs. Gas diffuser 199390 must be present for proper shielding-gas coverage.

Steel body resists spatter and heat

Copper finish reflects radiant heat and reduces spatter adhesion during daily MIG welding. Tapered shape directs gas flow toward the weld pool while keeping the tip recessed. Threaded mount stays secure on spool-gun barrels even when the gun is manipulated in tight joints.

Questions about this item

Should I pick the 5/8 in bore or a different size for my Spoolmatic gun?

The 5/8 in bore matches the FasTip contact tip series and the 199390 gas diffuser used on Spoolmatic 1, 15, 2, 3, 30, XR, XR-15, XR-30 and XR-M guns.

What does the 5/8 in bore diameter do for my MIG welds?

A 5/8 in tapered steel bore delivers consistent gas coverage around the FasTip contact tip, reducing spatter and protecting the weld pool on standard-duty MIG jobs.

How does the threaded connection affect nozzle changes on the Spoolmate 3545?

The threaded connection screws onto the 199390 diffuser, so the nozzle stays aligned during high-amperage runs and can be swapped by hand when it wears.
