Flux Nozzle

Use with flux cored wire only. Narrow design allows access in tight spaces and provides better visibility of puddle during welding.

Push nozzle over contact tip and adapter until it is seated onto adapter. Contact tip will be exposed approximately 7/16 in (11.3 mm) when installed properly.

MIG Nozzle

Use with solid or flux cored wire.

Push nozzle over contact tip and adapter until it is seated onto adapter. End of contact tip will be flush with end of nozzle when installed properly.
