Millermatic 211 with FluxCore

[dave63]

Hello all,I just baught a Millermatic 211 and intend to use flux core wire. Can I use the standard nozzle that came with the machine? Also, will the 'autoset' feature work with flux core wire?Thanks for your thoughtsDW

[Broccoli1]

Auto-Set is only for using shielding gas.

You can use the nozzle that comes with it.

I don't know about that...

There are times that gasless fluxcore can be darned useful...

like outdoors in breezy weather on farm equipment...

Don't forget to change the polarity to ELECTRODE NEGATIVE for gasless fluxcore...... orherwise it WILL run like CRAP..

See section 4-4. " Process/Polarity Table" & Section 4-5 "Changing Polarity" in the manual

Cool, thanks for the replies. Just when I thought I was set up and ready to go I had heard that I might need a different nozzle (glad to hear the original nozzle will work). I intend to get gas at some point in the near future but need to patch a hole in the floorboard of my wife's Taurus this weekend. I'm really looking forward to trying out the Miller.

Your going to struggle with flux core on Sheetmetal.

yes...very....

Oh, I thought flux core might be better because its quite rusty and dirty.

I was going to cut out what I could, clean up the area with a wire wheel where the join will be and put in some 18 gauge sheet.

There is a guy near me that I seen on craigslist says he will sell me a full 80cuft bottle of 75/25 for $150. Perhaps I should just buy it now.

just make sure the bottle can be exchanged or refilled easily.

[dave63]

I think I'm going to give this $150 bottle a miss. Seems a bit suspicious. They guy says he works for a welding supply company and can get various sizes. When I called the company that he says he works for the price was a little over $250 plus tax for a 75/25 mix #3, 80 Cubic Feet.

I'll either bit the bullet and buy a legit bottle or use the flux core wire that I have.

Here is a picture of the task at hand. I plan to do the repare from the top. I have that gas line thats in the way too. Hopefully I can move it out of harms reach or shield it by sliding a piece of metal between it and the frame. Do you guys have any advice for this little project? I'm not worrried about it looking nice, I just need to keep the elements out for another year or two.

Bottles Ron about 150-200 depending on size and then price of gas, 250 is normal

Hey Dave,

I would try to find a 125 cf bottle, refills cost almost the same as 80 cf. Most LWS will exchange 125 cf and smaller with little hassle.

Thanks for the tip. I'm aware that the bigger the bottle the better value you get on refills but I also want it to be somewhat transportable. I plan to stop by Airgas tomorrow and see what they have. Perhaps 125's aren't as big as I'm thinking.

[Cgotto6]

It's possible with flux core, just maybe not as clean and easy to work with as mig welding it. I would suggest you just tack it into place, and run a good bit of seam seal on the seams to keep the elements. Seam welding would be much more difficult and time consuming. Either way good luck with the project.

Cool, thats for the good idea.
