Anyone know what the physical difference, between the nozzles for for MIG and flux welding?

I purchased a used WeldPak 100HD, that had no nozzle. My local welding sold me a Weldmark WMK21-50 nozzle, but I'm not sure it is for gas and I will be using flux.

Re: Lincoln MIG/Flux welder nozzles.

I believe you're calling the Nose cone the nozzle. the perpose of the nose cone is to transfer the sheilding gas to the weld puddle. So you don't need one for flux core welding. Which is the reason that most welders that are set up for flux core welding doesn't come with the nose cone.

Good luck

A nozzle will run inner shield wire and not know or care that it does not have gas, as long as the OD is the same. At the end there is a copper tip (contact tip) it screws into another piece if for gas has holes through the side of it (defuser). But it will let the wire pass without gas. Unless by flux you mean submerged arc,,,,

Home depot has both style cups, the bigger one is for gas.
If you can fit a pensile between the cipper screw in tip and the inside of the cup its a gas type, the flux type is closed.
Using the gas type cup with flux just gets spatter all over the copper tip.


Flux core wires tends to be bigger diameter, so if its thw wrong one, besides getting a flux stye cup you need to change the copper tip, thats what I had to do.

for flux core if nothing else you can see better without the cup.
auto darkening helmets are really nice.
