Tips should be the same. They do get matched to wire size though. The stuff you are talking about is anti-spatter and you can get it in spray or gel form. It keeps the weld spatter and slag from sticking to the tip of the gun.

Electrode negative if you go flux core.

 

ok thanks guys

 

Good timing. I'm just setting up my new Lincoln 180 and had the same question about the large nosel tip because someone in a video said to use different tips for flux and gas but the machine only comes with one.

Good luck with your welding. I hope to power mine up for the first time tomorrow. After work today I'm picking up scraps from a local fab shop to start my learning/playing.

 

Hi Rick and DC Clamp,

There are different NOZZLES- the nozzle is what surrounds the tip, the Tip is the little copper piece that the wire feeds through and you only need to match the Tip with the size wire.

.023 Tip for .023 wire
.030 Tip for .030 wire
.035 Tip for .035 wire

Although there is a Fluxcore nozzle available it is NOT required to weld with Fluxcore wire- you can use the gas nozzle that came with the machine.

Some folks even run Fluxcore without a nozzle but your Tip will get pretty buggered up with spatter.

Thanks Ed. I'll pick up a Fluxcore Nozzle soon. Going to start the journey with gas.

 

Thanks for the input-happy welding

 

Ok so I want to now weld with gas. I have a bottle of gas that came with the machine-in going from .035 flux core wire to ,025 gas wire do I need to change out the drivewheel-not sure I am using the right term-thank you.

 

Drive wheel for flux core is knurled although I've had no feeding issues with the V groove which is standard for solid wire. The risk with V groove drive rolls with flux core is crushing the wire if you tighten it too much. If my machine had a longer whip, I'de be more concerned about it.

Make sure the drive roll is sized for the wire though. Should be stamped on the side of it.

 

Ok great thanks alot

 

You can't feed .025 wire with .035 rolls. They won't grip the wire no matter how tightly you adjust them. Many feed rolls have two grooves in them ... not sure about your Lincoln. They will be marked on the side. For .025 wire, turn them with the 25 (or 23) facing out.
