New 210 Need Wire

[Royal Fe]

Just unpacked my new MM210 and need to get some wire tommorow morning. I have a tank of CO2 and will use it for shielding until I get another cyl for 75/25. Is there a wire that I can use with both types of gas? I guess my question is where do I start with wire size? The material I will be welding is 16 ga and up.

Not to put words in Dans mouth,I will anyway.He likes .035 wire even when welding with 16 gauge.I think he uses 75/25 when doing when using it though.

I like .030 with my little machines in that guage,and .035 with my bigger ones.It just seems to work out that way for me.

Give us a update on how you like my favorite Miller copper Transformer machine.

In my opinion, when welding 16 ga and thicker with a machine the size of a MM 210 or MM 251 for that matter, an .035 E70S-6 is going to the best choice for a general purpose wire size.

Some machines don t perform very well with CO2. My MM 250 at work does a terrible job with CO2, but my Ck Systematics 175 does a very good job.It produces spatter free welds, that almost look like they were ran with C25. So, I m curious to hear or see your results with your MM 210.

ROYAL FE...........I'M CURIOUS IF YOU HAVE A CO2 GAUGE......... THE ONE THAT COMES WITH YOUR MACHINE, IS AS I RECALL FOR 75/25 AND ARGON.......... I THINK YOU WILL NEED A CO2 REGULATOR.................ROCK................

Last night after reading the Owners Manual a few times I realized that the guage is 75/25 that came with the machine. I think thats the excuse I needed to get another tank today.

I do have a CO2 Guage but it's the beverage type. I know the main difference is that it's stainless but It will probably do the job.

Well, off to get some wire and rent ANOTHER tank of gas. Think I'll start with the 35 wire and go small when I need to.

Guess what I'm going to weld first with the 210?

ROYAL FE...........I'M GUESSING IT IS GOING TO BE ANOTHER DESK AND PERHAPS FOR THE SAME SECRETARY AGAIN.............?.... OR WOULD THAT BE FOR THE SAME COMPANY AGAIN..........ROCK..... [email protected]

All of the above. Rebar fence, fire pits, BBQ grills,Gate for the wife/ and neighbor, Benches for a local coffee shop, and even a giant 1000lb sculpture for my yard, the list is growing! One of my neighbors saw the Miller box and said "Can you....." you know what I mean. Can't wait to get started. Boy with a new toy! My daughter wanted to know if I was going to sleep with it last night. I said "of course"!

Oh yeah, ROCK....this is for all the execs reading/ watching etc. the list is way to long to quote but the main factor I chose Miller is this forum with quick response to questions. O course the preverbial nail in the other brands coffin was the tech. support that has been quoted here on many ocasions but especially the board thing with the 251. JFYI

P.S. Ordered it Monday afternoon and it was here by Noon Wednesday. When your good SERVICE is the best!

ROYAL FE ............. THANKS AND I KNOW MIKE WOULD APPRECIATE IT ...........THOSE WERE HIS ACTUAL WORDS WHEN HE SAID THAT IS HOW WE CHOOSE TO DO BUSINESS......BUT WE DO, DO BUSINESS LIKE THAT........... AND ON ANOTHER NOTE...... HIS SON (MIKE'S) SENT ME AN E-MAIL THIS MORNING......... SEEMS THE TURKEY SCORE IS MIKE.........ZIP.............TURKEY'S AFTER 2 DAYS ARE GRINNING.... BUT HIS SON HASN'T GOTTEN ONE EITHER......... THAT MAKES THE SCORE 4 TO ZIP............... I ALSO NEED TO MENTION HERE THESE GUYS ARE EXCEPTIONAL BOW HUNTERS... NO GUNS FOR THEM.......................WISH I WAS THERE BUT DIDN'T GET DRAWN FOR THE SPRING HUNT..........SEE YA..... ROCK........................

Question. My CO2 regulator is in PSI and Bar is there a chart I can convert to CFH? Is there a way to convert pressure to rate of flow? Hate to by a regulator if I have one that'll work.

By the way my Father in Law killed a 12" beard the last day of the season. His score 1 to 5 Mine 4 to zip.

To use your CO2 pressure regulator for welding shielding gas.

If your pressure regulator creeps past set point more than 2 to 5 PSI when downstream valve is closed then it must be fixed.

Way 1. Buy a welding gas flowmeter and attach it to the regulator outlet fitting using a short piece of pipe called a pipe nipple and any pipe bushings or adapters required to make it fit. Then set your regulator outlet pressure to what is required by the flow meter. The flow meter should include valve to adjust flow rate. Flowmeter has tapered tube with weight that rises to indicate flow rate.

Way 2. Replace regulator's Low Pressure gage with flow gage. Then remove regulator outlet fitting and install flow gage outlet fitting that has metering orifice size specified by flow gage. Orifice size should be written on face of flow gage in small print.

I have a CO2 beer regulator that has left hand pipe thread outlet port with a hose barb installed. The only way to adapt that to flow meter is with hose from regulator hose barb to hose barb on flow meter or to hose barb on flowmeter outlet fitting.

Caution: Some CO2 regulators are only rated for 1800 PSI inlet pressure. This means you can't later adapt it for use with Argon, Argon mix, or Helium gas cylinders that normally are filled to 2250 psi or 3000 psi in USA.

PSI and BAR are units of pressure not flow.
1 BAR = 14.5 PSI think of it as a metric atmosphere.
USA uses 14.7 = 1 ATM

I was in welding supply shop when some engeneers from local navy base came in with broken regulator. They thought a regulator was closed like a valve by turning the adjusting screw clock wise or all the way in. They couldn't understand why they couldn't stop the regulated pressure rise when they open cylinder valve. They thought their new regulator was defective. They only broke the LP gage and unknown internal regulator parts.

Roger, get their email address and send them the link to the Navy Welding manual.

The real stupid thing was lots of helpfull knowledge at their naval base.
They worked at Naval Coastal Systems Center home of Experimental Diving Unit and Naval Diving & Salvage Training Center. Lots of people there with knowledge of gas systems including engineers.

They had a bottle of Helium they needed to reduce to low pressure for some unknown reason. Not the first time I have seen egineers that didn't realise how little they knew.
