- - By rcwelding (***) Date 08-30-2011 23:23
I am about to trade out some work for 200lbs of 7024 and 200lbs of 7018 from my LWS.. He said that it was difficult to get 7024 in tins or in sealed box's..

So my question is.... Being a low hydrogen rod... Shouldn't it be a common practice to get it in a sealed container..?? And shouldn't it be kept in a rod oven just like 7018..?

  This might be a dumb question it just Shocked me that Praxair would have a difficult time getting 7024 in a sealed container..!!

  Thanks

7024 is not a Low Hydrogen electrode.

Auditors don't like non-low hydrogen electrodes in the same oven as Low Hydrogen, a big no no.

It by no means hurts to keep them high and dry even warm but not with Low Hydrogen Electrodes

Good Luck

Well there you go..!! I was always told they were a low hydrogen rod.. 

Thank you for clearing that up for me..!!    Marshall

That is 7028 that is the lo-hy jet rod
Hope this helps
Thank you for your time and consideration
Sincerely,

Here's Hobarts info.  Seems they have a concern about high humidity.

E-7024 RECOMMENDED WELDING PROCEDURES:
GENERAL: AC or electrode  negative, work positive (DCEN)
ARC: Short arc or drag technique
FLAT: Use faster speed of travel; angle electrode 30° from 90°
VERTICAL-UP: Not recommended
VERTICAL-DOWN: Not recommended
OVERHEAD: Not recommended
STORAGE: 60°F to 100°F, (20° to 40°C) and below 50% relative humidity or holding oven 
  @ 100° to 120°F (38° to 49°C)
RECONDITIONING: 250°F to 300°F, (121° to 149°C) for one hour @ temperature

rcwelding,
I'd inspect those 7024s real good. They are a bit delicate and flux can be easily damaged. Even in the factory sealed containers.

Thanks Superflux.. I will check them out..

The guy wants to trade a new set of Victor Journeyman II torches, O/A bottles, Jack stand, 400lbs of rod and a little money for one of my BBQ Pits.. We are still negotiating..

We'll see how it all turns out or if it will even work out good for both of us..

Notice the holding temps if you use an oven to store 7024's as shown in 99205's post. When the temps get up there where lo-hy is stored at, 250°F and higher, the flux on a 7024 gets baked too hard/dry and it crumbles off the rod...sometimes it will crumble off in large pieces as you are welding ...then porosity will show it's ugly head because of the lack of shielding.

So 5p+ and 7024 Jet rods will live happy together then right..???

  I know this has been discussed to death on this forum but 5p+ just needs a dry place to be happy right..?? As in Rod ovens not necessary..

  I know5p doesn't like the heat in an oven like 7018..


Edit.. I have posted it on here before but this is the pit I am trading him.. Its 3yrs old and made from a 150gal propane tank..

Correct

>and a little money for one of my BBQ Pits.. We are still negotiating..<


Ok, you gotta show it off with a pix here...

The only type I ever made was the bullhead both ends BBQ.

I attached a picture to my last post..  Its not to fancy but it cooks good..!!

I used to pump the propane tank full of truck exhaust to displace the oxygen before I cut them... I have built probably a dozen pits with this design and that process...

I learned on this forum that my poor guarding angle had to were a bomb suit as well as work over time to protect me while I was cutting it using that procedure..!!! :lol:

So I haven't built one since... I'm still researching and trying to find a 100% safe way of cutting these.. I can get the tanks for $40 all day long so I would like to continue using them if possible..!!

If you purge any tank with Nitrogen you will be able cut it without it becoming a bomb.

Just do not use truck exhaust, I for one would like you to keep building BBQ pits.

It look's good

I started the discussion about xx10 or cellulose rods and moisture.
So I will defer my opinion on this.
Have a nice day

If the rod size is over 5/32, what are you going to weld with it and what machine are you going to use. To run a 3/16 jet with a SA 200 you need to be Max and 40. Really pulls that Red Seal down. A lot of guys weld too cold with a SA 200 because you really clean the valves and running at Max really test the duty cycle on a 200.
Unless you are planning on doing a lot of flat welding, I would pass on the 7024. 200 pounds of rod would make a lot of inches of weld. And remember, you are stuck with flat. (I know it CAN be used in the 3G but have never seen anybody do it.

I have a Lincoln Vantage 400 that will run up to 500amp.. I can run 5/32 and it wont even break a sweat..!!

I am hoping to get into a rig up yard.. Everything in there seems to be 1/2in or thicker.. They seem to like running 7024 if they can..

Good luck
At my best, I was never that good.
But Vantage users are so much better:eek:
Was it on a I beam or angle? Than you should run it on A/C runs better in the corners.
Probably pipe or plate, if running a Vantage
Have a nice day

I love my Vantage... Are they the best machine out there..??   Heck if I know and I don't really care.. It works for me and it pays the bills.. 

Just because I own a Vantage doesn't in any way make me any better or any worse than the next guy..

The last job I was on, I had an old timer out weld me so bad I wanted to go home crying to Mama and he was using a 300 Red D arc... Then there were a couple other guys there running old 200s and I ran off and left them in the dust..

Having a good machine always makes you better but it Dang sure doesn't make you the best..!!  I'm not the worst welder out there and I'm DAM sure not the best but I'm trying my A$$ off to become the best everyday...!!!

My machine loves to run 7024 and I rather enjoy it as well.. Its fun to roll in a ton of rod in a short time..

Now I'm just hoping I can get the right hook up and live in a rig yard for a while..!! lol

The mention of horizontal brings 3G to mind but it is 3F that is the position for 7024.
Try 3G and it will run all over your boots.

There is the matter of economics running the old "iron powder" rods with a SA-200. Several years back could suck a full gas tank dry in a 12 hour day, sometimes less than 12 hours. With today's gas prices that is a lot of bucks. Jet Rods like a lot of heat, they will let you know when you are trying to burn too hot. Most guys I know, burn'em too cold.
