Hi folks. I have an argon tank for my little Lincoln 110 MIG welder. When I use it, I pretty much open the tank and have at it. I ***ume that my welding rig meters out the appropriate amount of gas. Does it? Or should I use a pressure regulator on the argon? If so, what kind of psi should I use? Does it matter is it's 18 gage steel or 0.125 wall tubing? Shouldn't the gas rate be adjustable? Wouldn't it matter? Thanks in advance, Matt
you should open it to about a one and half turns and keep opening it untill the metal surface you are working on starts to melt.

Deuce, you need some sort of regulator as too much gas will A, waste your money, B, cool your weld to much so you don't get a good weld. I tried the cheapskate regulator that came with my cheapie Mig SIP130 but soon invested about $30 in a proper adjustable reg and a proper sized Argas bottle.
i mean you should always open the tank one and half turns then start it then starting to put it up against the surface check to see if a metal puddle is starting to form if not turn up the heat untill the puddle starts to form then continue to weld in whatever postion you are in. if it is too much the puddle will be excessive and you could burn straight through the metal.
Thanks, Morrisman. Hey, ********, what the hell are you talking about? Are you trying to say that argon is a fuel for MIG welding? You've got **** for brains, judging from this post, and your other "hey a question" post. Love, Matt
Hell, I don't even know HOW to weld and that sounds batty to ME! (I think he's talking about oxy-accetalene welding...sorta! )
the argon is used in oxgen actlen or how ever you say it. so i am telling him with that in mind and sorry i thought when people asked questions they would get an answer not a dumb responce making fun of someone. so if he is saying argon is used with a mig then he is wrong. i'm talking about argon with oxygen and not leaving the tank wide open cause when you start it. cause you can cause i flash that can hurt you or you can burn through the metal. so i might not be able to type it at times cause it is hard to explain but my welds speak for themselves.
Darkhorse, Argon is used in MIG welding (Metal Inert Gas) to prevent oxidisation, burning and pollution of the weld pool, and to keep the welding tip cool. You can also use Carbon Dioxide, (CO2) but Argon is better usually, as CO2 is not actually inert. I think you are referring to acetylene gas, not Argon.
ok sorry i'm tired i'm just trying to make sure the kid doesn't blow his head off it's been a while since i had to explain welding i just do it everyday of my life.
ok, i'll give this a whirl.... yes, you do need argon when welding with a mig...(the most common mix is argon/co2.) as for a regulator, i would suggest one. save you ALOT of gas in the long run. the tank i have has about 1200 psi, you will only need between 20 and 30 psi to have it shield the weld properly. (my welder seems to like 25 psi) from what i was told at the welding shop when i switched from flux core to gas was that when welding, you should be hearing the sound of sizzling bacon. get a regulator.($30 at harbor freight) set the pressure to the welder at around 20 psi..test it. sound like sizzling bacon??? if not adjust psi upwards till it does. i'm no pro, but that is what i've learned and it seems to work for me. if nothing else take a trip to the local welding supply shop...they should be able to help you dial it in, as well as sell you a regulator.
Deuce... Does your MIG have a small br*** unit (with a gauge) on the end of the hose where its screwed into the tank valve? It should. Some of the smaller MIGs were equipped with a preset regulator that works fairly well in the garage. Outside you will find any breeze will blow the gas away from the weld area before it's done its job, resulting in ****py welds. An adjustable regulator in those conditions would be nice but indoors its not that important on a rig with limited capability. I figure you MUST have some sort of regulator already or you would have just blown the hose completely off the machine! DARKHORSE... It's tough to answer a question if your unsure of the names of the items you mean to describe! It's important to TRY to get that stuff right man! Difficult enough to get your meaning across with the written word as it is!!! TEXT is very unforgiving you know! So your not as typing-articulate as you could be...big deal! No reason to doubt you can weld with the best. Don't rush into answering things and word what you do ask or answer as well as you can...things will come around for ya! Don't be so anxious! Best of luck and welcome aboard! Bill
like i said before i've been working all day and i got mixed up. so i'm sorry and if you don't like my post then don't answer them ok i'm asking for help not for a lecture.
also, your amperage setting, and length of wire stickout can effect the sizzling bacon sound... the sound (next to the appearance of the weld) is the best way to gauge how your machine is running, so when you get that sound, you know you got it dialed...
A LECTURE? HA! Calm down and reread the lecture bunny...I mean buddy. I offered you a WELCOME. Do with it as you please. Bill
Hmmmm...Fair enough Darkhorse...no problem. ANOTHER post confusion caused by that "RE: so and so" header that shows the message you posted from, but NOT who you were actually talking to or about! (how could it!) I've watched that thing cause quite a bit of confusion over the past little while... We need to learn to disregard that! It tells LIES!!! LoL Bill
Darkhorse- you weld every day and you get acetylene and argo mixed up a couple of times in a post? Hopefully you're a bit more knowledgable than you sound.....I'll watch the news for explosions down there in dade county!
like i said i was tired i get mixed up alit it happens to all of us like i said i'm sorry so drop it and end this whole thing
Install a proper regulator. Dont bother with c02. I recommend a good 75/25 mixture. When you open the gas bottle valve open it FLLY and backseat the valve, it is designed to do this. Start out with 10-15 CFM of FLOW. More detailed explanations can be found and asked at either: www.weldingweb.com or http://www.hobartwelders.com/mboard/
[ QUOTE ] Dont bother with c02. I recommend a good 75/25 mixture. [/ QUOTE ] again, huh? what do you mean "good" and what do you think the 25 is? seems to be a lot of misinformation in this post. read the paperwork that came with your machine. Paul
Co2 is too cold of a weld "good" meaning good general gas to have in the shop for multi-task welding. yes I know what the 25 is in a 75/25 mix I keep 3 bottles of gas in my shop 100 % argon: For Tig 75/25 GP MIG welding (HH175 and HH120) Tri-Mix for Mig welding Stainless
ok my bad, when you say CO2 you mean straight CO2 and when you say 75/25 you mean CO2 is ok when it's mixed with 75 percent Argon. and by good you mean what comes in the bottle not some home made **** you got from your cousin's wife's brother. I must still be upset over ********'s inane nonsense. Paul

Some of the smaller MIGs were equipped with a preset regulator that works fairly well in the garage. [/ QUOTE ] Thanks, Bill. That's the answer. Like I said, it's a little Lincoln 110, and it does have the preset regulator. So, to paraphrase ****house: Doesn't the "IG" in "MIG" stand for "inert gas"? Or is it "incediary granade"? I'm not sure 'cuz I'm tired and any one could mix those two up. All I know is that "argon is used in oxgen actlen or how ever you say it". But I do it everyday of my life, I just can't explain which is which. I'll just crack something one and a half turns and keep on turning until something metal melts. Hey, I'm not looking for a lecture, just some help, which is why I post some seriously dumb ****. Is that about right?
