????? about mig tips and nozzles

[SteeL_ButcheR45]

1. Should you use one type of tip and nozzle to run solid wire and another type of tip to run flux core?
2. What is "spray" welding and does it use an entirely different nozzle and tip?

TIA,

The tip doesn't matter. Just use the correct size, or sometimes one size bigger if you have trouble with FC. I have never had any trouble, but have heard that sometimes the FC isn't as uniform in diameter as solid. The nozzle is there for use with shielding gas and isn't really necessary for FC. In fact, it kinda gets in the way when using FC. There are "nozzles" for FC that are just there to keep the tip from touching ground and to keep spatter off. I don't use one, though, yet. I just spray the gun with antispatter spray.

Here is a link to some docs about welding that are actually pretty helpful IMHO. There's also some on the Miller website, I think.

Just my 2.5 cents.

For short arc, have the tip flush with the nozzle end, and for spray, recess the tip. Miller makes a nozzle for the 210/251 that is longer, but you can adjust the standard nozzles in and out as needed.

ditto Dave.....but I use Pam cooking spray insteat of spatter shield ...it is cheaper and smells good cooking ...

[Eric Carroll]

How is pam cheaper than anti-spatter?most anti-spatter sprays are ok to paint over with out much clean up,I doubt pam is formulated with this in mind.

Same ingredients! Unless you get the "flavored" PAM. I use the garlic stuff when I use it at all. Smells good and takes paint fine!

Danny,

Spray arc is high enrgy, high deposition rate GMAW using an argon-rich shielding gas, like 98/2 on my MM 210. You'll need a 200-amp class power source to do it on steel. The tip and nozzle are the same as for short-arc, but the tip needs to be recessed about 1/8". You have to move fast!

I don't think it is either, but if ya read the labels, they both seem to be almost the same.
However, I haven't tried anti-splatter for cooking yet...

Pam as anti-spatter spray... Hmmm...

I wonder how that was discovered? Kinda like the guy who figured out you could milk a cow. What did he think he was doing?

[SteeL_ButcheR45]

All the info is very helpful, I do have a can of anti-splatter spray and a container of nozzle dip. I also bought a .030/.035 groved-knruled wire feed roller and that cured my feeding problem while running flux core wire. Anti-splatter for cooking and garlic Pam for welding you guys are a mess I have an IM 250 so I have the 200 amps needed for "spray" welding. What is the advantage or what reason would one use "spray welding"????

Thanks Again,

Yep,
That's a real 'head scratcher' for sure.


Along those lines,,,,,, here's something I've been pondering for several years:

Was that perhaps the bravest person in human history or what?

Some flux-cored wires are meant to run better on a spray mode. Self-shielding wires of course don't run on spray. Stainless flux-core and aluminum mig run better on spray. The advantages on running a wire in the spray mode are less splatter and they are just nicer to weld. Not all flux-cored wires need 98%Ar/2%O to weld in the spray mode. That particular mix is generally used for Stainless or Low alloy wires. It just depends on the wire. Some of the wires that I weld with use 75%Ar/25%CO2 to spray....Make sure that you use the proper shielding gas for your wire. In order to get a spray, just crank the heat up.

[Zapit]

I've always been told that you need a minimum of 80% argon to achieve a true "spray". This higher percentage of argon allows the gas stream to be ionized (at the proper voltage).
Now this ionized gas stream becomes electrically conductive so that the wire can melt off without having to touch the base metal thereby causing the fluid droplets (mist) of filler to spray into the joint.

whats amatter you guys never lost a bet???
