Gas type m2

[EMB5530]

I did little searching on TBN, but did not see much about welding gasses for MIG.
I have done a little amount of wire welding(enough to be considered dangerous) but I am used to stick welding. I have just purchased a wire welder.(after years of wanting to get one, or a TIG) I was wondering if there are many negatives to using m2 gas for my steel welding(and also stainless). The main reason is: the company I work for keeps this around(and also a buddie who lives very close) so if I need an exchange even on Sundays I can just go get one of theirs and pay to have them refill mine during the week while I am working wherever I am during that week(construction life). I have also noticed it lays a much cleaner bead(but it sounds a lot different than I am used to. How is the penetration diff is the weld any stronger/weaker? So what are the negatives? If any. And so on...

Thanks to all for any info

Have any of yall used m2 before to know what I mean by sounds different
It dont sound like the bacon cooking like im used to.

More like a hiss instead

OK, I'll bite what is m2 gas? I Googled it, and nothing came up. So enlighten me please.

I have never even heard of m2. What company sells it? It might just be a stores name for something like 75-25.

90% argon 10% c02
linweld is the main supplier

Only thing I found refers to dual shield, flux core with shielding gas.

Oh I see, never heard it called that before. Strange I just started playing with that mix.:laughing:

what is it called where you buy it?

 

[deereman75]

I think it is just called 90 10 at most places.

 

[Shield Arc]

90/10:laughing:

 

[EMB5530]

90/10:laughing:

well I guess that makes sense

How do you like using it?

She's fast, and deposits lots of iron. That picture was .045 wire on 1/4 inch flatbar. With .035 wire no problem making a honest 3/8 inch fillet weld traveling very fast.
Here is an .035 Lincoln L-56 wire.

Also probably called C10 (for 10% CO2). M2 must be a particular brand name

90/10 is the minumum mix to effectively do Spray Transfer on mig. ( Unless you want to mess with Praxair Stargon 77/20/3 which is 3% 02 it Gets you close to Spray but is a dated mix) 90/10 costs a little more than 75/25 but worth it in Spatter Reduction and you don't have to deal with the Oxidizers that Stargon has in it. You don't have to Spray with it you can run it short arc too. The big deal with high argon mixes up to 98/2 is that they are Pulse Friendly. If you have a pulse power supply, You would be doing it an injustice by running less than 90% Argon. When you get into Stainless, You will enjoy 98/2 or a mix with a little helium. For the most part, 90/10 trumps 75/25 for a little more $ and much less spatter. Bad news is it's not available in small cyllinders. Oh well.

Thankyou for the info:thumbsup:

Can you run it out of position also?

 

[yomax4]

Yeah, It's the machine and wire more so than the gas for out of possition welding. ( i don't like out of possition welding. ) unless it's Aluminum on twin pulse. All you stick guys are the out of possition kings.

 

[Shield Arc]

( i don't like out of possition welding.)

I don't like it either, funny how you just can't get away from it tho!

Havent you guys seen the razor commercial. Just use the right blade when you shave and it will turn your world upside down. I suppose you have to weld the top first before you shave.:laughing:
