7018 weld advise. Pics.

Co2 cylinders use CGA 320 valve connection with plastic washer between valve & regulator.

WARNING there are also cylinders containing something called "Beverage gas" which a mix of Co2, Argon & Nitrogen used on a lot of beer and beverage systems. Absolutely useless in welding unless you need a purge gas to work on a fuel tank.

Difference between a beverage regulator & MIG regulator is volume capacity. Beverage regulator will freeze needle to seat at welding rates over period of time.

Lot of welderbatrers get worked up bout frost on outside of regulator.. Happens, bot meaningless to gas path inside regulator.

Beware of small Hobart ITW regulators on Co2. ITW built dem off shore wid crap brass dat corrodes wid pure Co2 and locks needle up to seat. Real easy to spot because ITW saved 1 penny per regulator by not using thread compound on fittings into regulator body. Dey built to leak.

One reasons why there are so many types of rods. The numerical designators separate rods into functional process groups based on requirements of the metals and the end use of the welds. Brand names tend to have many nuances that have nothing to do with end results. That's why welders brag up certain brands and others **** them. I can remember when pipe welding we would not use anything but Fleetweld 5P right, wrong, or indifferent. Since I have used many brands of the same number designator and really can see no difference. 6010 and 6011 are formulated to perform the same function on 6010 (DC Negative) and 6011 (AC). 6011 will work best on DC at DC Positive. Negative stinger is sometimes called "Reverse Polarity". If necessary rods designed for AC tend to work better at DC Positive (my opinion).

I ran the 6010 with dcep. Are you saying its a reverse polarity rod?

 

[Hersheyfarm]

I just use flux core. How long you get out of tank with mig. Can you go through a role of wire?

Let me figure out pics

 

[the old grind]

Save pics to a folder then click the icon in your post with a pic of a tree to post each one. Select 'from computer' and browse to the pics location.

Click to upload the pic and give it a few seconds to complete. As always, be cautious with 'page back' and go with 'advanced' to edit and preview.

btw, I've had difficulty posting pics direct from iPhone thru' PC. Never a prob if I park 'em on desktop to post before cataloging/storing them by category in the cloud, pen drive, etc.

Tig Stainless with straight Argon yes. Mig not so much. For Mig SS I use a Tri mix of argon/co2/helium. Or 98Argon/2 CO2. 2 Oxygen works with argon too. Kind of an old mix. Many still use 75/25, 90/10 on stainless mig as well if they don't mind the black and some spatter.

 

[yomax4]

When I worked at my LWS years back we had CO2 with the standard valve 320 CGA. Then we had what ws called Fountain tanks that were the same but they could get more $$ for them. Both worked for welding or applications where you need just gas. Different color neck. Then we had siphon tanks that had a dip tube and would deliver liquid. For wine it was always Nitrogen. Pretty sure this is accurate. Not sure what has changed but I'm around distributors almost everyday so I will refresh.

Lot depend on filler in MIG SS. I can run E70-s6 filler on SS wid straight Co2 and create some unknown alloy in deposit. Far as girlygasses I agree wid Ed Craig. 99% salesmanship 1% truth but sire did wonders for AirGas profits. Oxy add nothing but heat. Helium add heat too, just like back in old days of Heliarc on DC.

Spoolgun really don't like Argon or Oxygen being present, Co2 major cooling to de gun. Course spoolgun only short passes anyhow.

MY world 99% steel so I perfectly happy running Co2. I gotta do aluminum I call Danny and he comes by wid Trailblazer & Cobramatic. Faster, better and cheaper den me screwing around.

SS, haven't seen enough over last 10 years to use anything but brass, everdur or stick 309.

Yep I run some CO2 as well. Newer imports run it pretty well.

 

[the old grind]

I'm doing so well with CO2 ('pure' from LWS) that I wonder where/when the 75/25 mix is as good or a better option in any case, esp for mostly 'farm' welding.

btw, Expect me to gather tanks/mixes that I'll never know what to do with, too. :laughing: That's a hint that I'm 'all ears'.

 

[user.69169]

Well 10 beers, like dis. You best served to set aside few hours and read EdCraig on all de fancy mixes and particularly how dey came into being. Ed was right der in middle of it workin for gas company, and calls it like he sees.

I read some of Ed's writing and was pretty sure Ed wrong here & there. Foundout Ed was right.
Pay some attention to what he tell bout enginitwits & Purchasing screwin up weld lines.

You read enough Intrnuts you start to think girlygas control or minimize spatter. You just buy right girlgas and set regulator at right pounds and right cfm and set digital goobiewasser on and you got less spatter. Course 3 days later genius postin on how to clean liner and do he need a new tip or can he file.
HINT, 1 step forward = 2 steps back. Weld ain't in de machine. Weld between man's ears. Learn how to run machine like welder, NOT hot glue gun decorating cake. Once you do you might be ready to deal wid spatter.

Maybe 2021 we talk about cylinders and little bottles and dirty deals in gas business.

Actually you can run ether polarity. Better penetration with dcen with less splatter. Try both ways. Back min the old days we did our ASME code pipe test coupons with 6010 dcen all the way. Times, weld procedures change, and new rods come on the market. I am still old school, not really fond of 7018 even though I have it and use once in awhile for single pass on 12 gage-1/8" stuff. Keep the container sealed.

I am on my phone. I thought I had posted pics from it before. I don't see the little tree. Has Carl been on in a while? Great guy, I have met him.

 

[Sberry]

Ok, pic 3, 1/4 plate clamped to the bench, reach under which makes it overhead, 6011 no bevel. Pic 4,7018 2 passes, 2 I font remember and 1 is 1/4 plate no bevel vert 6011. Ok, 2 is 7018, a little shaky as I rarely do this anymore.

 

[Hersheyfarm]

I been working on some hvac stuff for my mini X and needed al plate 3/16 so I had to cut an angle iron down and attach it to the biggest piece I had. .35 flux core.

On a side note, I used a 3/32 7018 today that was in excess of 20 years old. Kept in a PVC rod holder. Seemed to run fine enough for me. How long does the weld have to dry before I use it? :laughing:

6 maybe 7 hour depending on humidity.

First time fellow asked me dat had to be around 94, he was good block mason needed work on his mortar mixer been neglected for years. Let him do cleanup wid needle gun and loose his hearing. Put new stubs and wiper holders on beater shaft and told him ready to go back to work. He looks over job and asks how long gotta set up before he can use.

Thought bout de question fer a minute, considered is frame of reference and told him it be fine by time he got to job in morning.

Figured he like farrier, works half de day wid head lower den azz, no way you convince either of anything. Worse den tryin to convince college graduate works in 8 x 8 cell all day wid a desk. Neither got any frame of reference.

Like some posts?

btw, I inherited a weld dryer from my grandfather. He was born in the 1800s and it was his first.

Of course it's pre-WW I and coal-fired.

Can you post pictures? Pre WW-1 pretty much make it a dryer for O/A welding since electric arc welding didn't get goin as commercial process till after dat war.

I asked a guy about welding or brazing a crack in the waneshaft trunion. He talked me into leaving it there for a new paint job too.

Then he got the virus and his wife says the paint booth is three months behind. Sorry, no 'before' pic but I can post one when I get it back.
