When I was a kid, my dad left an open container of hydrochloric acid in the shed. The next day, his lathe was completely covered with a nice even coating of rust.
I´ve heard that for cleaning rusts on iron / steel products, it´s best to stay clear of hydrochloric acid and use phosphoric acid or similar steering clear of chlorine salts... The reason I heard stated is the chlorine ions which cause the flash rusting - maybe this is why road salts are particularly nasty to vehicles too..??
Yes, chloride is very good in making steel rust faster. Dont remove rust with HCl unless you know what you are doing, how to treat the steel to protect it and how to remove every last bit of chloride out of the pores.
It took a year of my top tool box being in my truck bed, closed & locked but otherwise exposed to the weather, for all the sockets and wrenches to do that. I used a wire wheel to buff it off. What a dumbass! (Me)!
My dad used some oxalic acid in a slow-cooker in the garage to clean mineral samples. The vapors rusted all the fishing gear nearby, so the guides fell out of the fishing rods.
Woo! Welding! Reminds me of my youth learning how to weld. In short it was like climbing a tree ass first. I was 14 years old and we had this "summer car" or "field car". Crappy old toyota that we would drive on a flat field (our parents knew about this). One day we decided to fix the bonnet and bonnet which were rusted trough and full of holes. Weapon of choice, Stick welding machine. Oh boy did we learn fast that stick is not the right tool for body work... Good times.
First, thanks Tony. I appreciate you posting this and urging caution with pickling compound. I hope the rest of this comment drives the importance of that home for those who may be in doubt. Most of my work is on small components that are used in small robotics and other small mechanisms. That said I have used pickling compound extensively as an etchant. As a point of advice for others who might not know any better, a respirator rated for toxic fumes or a fume hood like they use in chemical labs is an extremely good idea. Some of that vapor got behind my face shield once and made my eyes burn for hours. That's after washing them thoroughly with water and then Bausch & Lomb's Advanced Relief eyewash. Now I mention this particular brand because that's what was recommended to me by the poison control hotline when I called it having had this specific accident. A friend was good enough to get me some as I couldn't drive at the time. The amount of pain I got from less than half a second of exposure was immense. I couldn't see because my eyes were watering so much. This brings us to the second point of advice which is to use the buddy system and not do this alone if possible. One's vision is a terribly price for a single mistake.
I wish I could like this video more than once. Great job! Now, ToT, please apologize to my wife because thanks to this video I just bought a TIG welder and can't wait to lock myself in the garage and weld all the metal bits I have into some kind of contemporary art piece that only I understand what it means. :-)
You are a great teacher - you take nothing for granted vis a vis your audience's knowledge. I learnt a lot about how TIG works at it's nuts and bolts end - and that kind of information is priceless to me as an informal learner. At the same time, people that know more than me on this topic will also benefit, I think. Thanks man, much appreciated.
Awesome video! At 36, I've spent a lifetime with arc & mig; but just purchased a Miller Syncrowave 210 6mths ago. I LOVE TIG! While I'm not able to weld as much as I'd like to, TIG sure comes in handy for machining projects and aluminum when it has to look good. Thanks again & keep 'em coming.
Never gets old seeing bronze being machined. I have the same torch except the flex head, I use it daily and love it with the Pyrex Furyk cup and stubby gas kit.
I just wanted to say that i really appreciate your videos. I find them to be very informative and entertaining. You also carry yourself very well. Thank you.
yeah! Pickling gel is some seriously hazardous stuff. It has both nitric and hydrofluoric acid.(soaks through flesh and dissolves the bone. not joking.) Both of these acids are a serious danger; wear protective clothing, a respirator, safety glasses, and gloves when handling; and make sure there is plenty of ventilation in the work area. Neutralize well with a paste of water and baking soda. unless you get alot of it on yourself, then you might need a calcium glutamate treatment at your local ER to neutralize the Hydrofluoric acid which has soaked in. Speaking of flesh... can you weld steak?
"The most experiences chemists are afraid to work with it." That mostly was and partially still is standard procedure in a lab for analyzing soils. Because its the only way to really get everything into solution. Many now switch over to aqua regia as it is non-toxic. But nothing to be affraid of if you can use ur brains. Its really "only" a problem for glass and if u get higher concentrations on your skin. This paste... get it on your skin... just wash it off right away. And yes, its HF. Its requiered to remove all the oxides to form a fresh, passivated surface. This fancy looking reaction at the end is simply due to the huge surface are, just like any little spark will light the steel woll and it will burn like crazy.
@@AldoSchmedack Yes they are different. And I'm pretty sure George stuart-vail he meant exactly what he typed. Here is a link to a pdf with exactly what Gs-v mentioned: euroshl.com/wp-content/uploads/2015/08/Avesta-Pickling-Gel-122.pdf TOT's pickling may have had hcl - who knows - I think he may also be right - there are many formulations.
Wow that was a very vigorous exothermic reaction from the pickling gel on the steel wool. I am willing to bet it got rather warm. just the vapor cloud alone just wow. Nasty, nasty stuff. Love the vids man.
I subbed! Your videos are so much understandable and well presented. No funky vocabulary and you actually care about explaining stuff - not too quiet either. ☺
I don't even know how you do it... you make these incredible, entertaining, informative videos one after the other, which should by all means be boring as hell... and they all turn out GREAT!
Your fourth law of thermodynamics is worth the price of subscribing. Finally I understand the why of something I've puzzled over for many years. Thank you. Also, somewhere in there would be the hardest part to replace (or the one you haven't a clue as to what it looks like) is probably the one that disappears. The fourth law of thermodynamics: If you drop something usually the most expensive component is the first piece to hit the ground and break.
Back when I was gainfully employed in a trailing research laboratory, I had oxygen and acetylene plumbed into my lab, with a torch attached. When I would light the torch and open up the oxygen to make a good flame, most times it would blow out with a pop. Now I know why: pressure too high. I'll be competent by the time I die. In the meantime, the public is being protected by my retirement.
Hey Tony, Love all your videos mate! Absolute rippers. Just one thing about this one... on Gas Lenses, they actually required a higher flow rate for correct coverage over the non-diffused counterparts.
I have seen a lot of welders in the industry use some electric brush to clean stainless tig welds. They dip the brush in a acid liquid and then they just lightly brush the weld and there is some sparks coming from the brush. And it looks perfectly polished after that, all the discoloration is gone. And then they just spray it with dish washing soap mixed with water and wipe it off to neutralise the acid.
i know right, i was waving away like a madman behind the screen, but no reaction, just like that time i invited him and his wife over for dinner, but no response...
I run WP-19 purely because around here, you can get industrial surplus dirty cheap and after buying and selling six welders in two year, the one I decided to keep is set up that way. Hello Dialarc HF :)
You inspired me to adapt my Chinese welder to work with the CK superflex hoses. I'm machining a brass female adapter with the 16mm x 1.5 male thread on the welder to fit the 3/8 -24 male thread from the CK hose. Wish me luck!
Thank you Tony, this was very helpful. I am not familiar with the many different tips. I have a Lincoln 175 none pulsating transformer. I can fuse well but adding material is still a problem. For auto-body work I use series of dots and fusing is mostly sufficient for my purposes. Thanks again, it was very enjoyable. Old Bob
I am on a college SAE baja team. We tig weld absolutely everything on the car. If it breaks at competition it gets tig welded together, even if it takes more time than borrowing somebody's mig and throwing it together really quick. We do have to drill holes in the frame (made of chromoly tubing) in order to fully weld around where the members meet each other. But we have never fed argon into the tubes, probably at least partially due to a limited supply.
5 pulses pr minute is nice. u have nice time to calkulate ur dips . Love ur videos. best ever. im gonna use ur video to tell my distributor to show them that stubby kit does exsist.
Ive got a CK Flex lock torch. Its good, you'd like it. Its great for welding behind things you cant get a normal torch head to, you just unscrew it, reposition and tighten up again. Its rigid enough to cup walk too, although I learnt the hard way that cup walking with the nice glass CK gas saver cup does not end well, it cracked, quickly. haha.
When I bought my TIG, it came with a #26 torch, big blue plastic handle with a button built it, nice and stiff current wire and separate gas tube all tucked in into the plastic cover, I was watching weldingtipsandtricks channel and Jody TIG weld and thought - god damn how can he be able to hold the torch in optimal position all the time and not dip the electrode or extend the arc too much... my torch holding hand would start to ache after 15 minutes of welding and shake etc and then I bought the CK superflex with a #17 torch, and what a difference it made... suddenly my weld beads got uniform, one freshly ground tungsten would last me for hours, no dipping, no extending the arc, can keep the torch angle mostly correct etc etc one thing that cheap original torch taught me is how to grind tungstens like a pro :)
You are my hero. Not only do you have some nice welding equipment but you have a lathe and a milling machine as well? And the best part is that you know how to use them all. Yep, my hero. I'm assuming that you have an engineering background?
Old Tony! Brazillian guy here again. You're the biggest reference for me and other "maker guys" in so many countries, i believe. But there's a guy, here in Brazil, that i just follow on youtube who you have to see!!! His channel is "Celso Mascarenhas". His videos are a little amateur but his work is incredible for a person who don't have hands! Please talk about this guy some day, he deserve.
Pickling gel is made from the molecular acid a facehugger uses as blood. Quite expensive stuff. The price makes sense when you take into account the risk to life for harvesters, and the research and logistics needed for interstellar and interplanetary travel. Cool stuff.
You know you run an impressive channel when a video has only been up for several hours and there's thousands of likes and (at the moment) only 4 dislikes!
Years ago I used to clean brick walls and concrete with Hydrochloric and Muriatic acid. it will destroy any clothing it gets on. Once I had a polyester jacket that the sleeves literally melted off after a day at work. And if you get any of the diluted stuff it in a scratch and the scratch heals over, you will form a big puss cavity under the scab sometimes it will eat straight to the bone on a finger.
apparently guys push the CK 17s to 200amps for short bursts so Im sure the 9 will run all day at 125 like CK says. Theres plenty of good info on torches online, but not so much in comparisons on youtube which really helps new guys (except jody like always has a couple really great tig torch videos). Hopefully you do a follow up when you get the new torch, this video really gave a lot of good simplified information thats not as easy to come by.
jason If you're ranking based on smartest and funniest, sorry to say, but AvE's got him beat by a mile. That's not saying anything negative about Tony either, AvE's just that good.
the last 3 quarters of weld class I devolved into TIG only on the Lincoln 375, can't beat it for weld quality vs production...no smoke/spatter, fine control, versatility....yeah
You should revisit your CNC welding video except with TIG. Also, thanks for the intro. I've been trying to convince my friends on the advantages of TIG and this helped a lot.
I have tried my hand at recreating some of Jody's arc shots. Had good luck using a 1.8 ND filter and my camera set to manual with a F stop around 18-20 and shutter as needed (trial and error). From looking at the work the camera around the 10-11 o'clock position seemed to give the best results for what looked good as was in focus for a decent amount of time.
Thanks! I also enjoy TIG the most (by far!) I am looking into the CK torches and this is exactly the information I need. So when you have it(the 80) I would not mind at all if you talked a bit about it in one of your upcoming video's.
I too find welding - MIG in my case - a means of escape. When welding, you really can't think of other shize. There's the bead, and not much else. No 'multi-track mind' can really happen. As an electrician professionally, there are equivalents akin to utility level unprotected conductors - which if shorted by accident could be your last accident, as they go off like a grenade. Not kidding! That said, welding is actually a safer way to take ones mind off the day to day. And you can have a little creativity to boot. Been wanting a TIG machine, but justifying money. Some day... Since not a machinist, your channel is actually a bit of an escape as well. Enough technical stuff to satisfy the mind (learn a few more things), enough comedy to satisfy the heart (figuratively), and to have a chuckle.
Made me go look at the two torches I have, yep #17 and #9. My #9 is a 'Flex Head' which I've found to be very useful (the tube between the coupling and the torch is bendy).
Fantastic channel Sir! I am slowly ploughing through your back catalogue and have yet to find a single duff one! I am on the cusp of entering into the tig world (homegamer), out of interest, does the Stainless become more magnetic after you have welded it, and does the pickling gel have any effect to it's magnetism? Thank you again!
A #9 water cooled torch with a gas lens was heaven. I miss it so much. Its hard to go back to a gas valve and lift arc, really i don't know what to do with my right foot.
Hi young Tony! Given comments below I won't be using that acid cleaner, but thank you so much for this video. I was wondering which was better for me, tig or mig, and you have solved that one. Cheers Bob.
Tony, I absolutely love your videos....especially this time - well, except the last one. It was freaky and gave me nightmares for 2 days. I figured you were invoking some kind of "Rule 39" kind of thing and I let it slide. :D
i remember in class we would have torches so hot that u couldnt pick them up bare handed and they were uncomfortable to hold by time u got to the end of the weld. and thats why i liked using the water cooled one. and that one air cooled one i could never weld right with it especially on aluminum it was an older machine and welded weird
if you ever have problems with a flare connection not fitting tight, go to the store and get some #6 or ~3-4 mm drill size copper washers.. you can use them to take up the space without having to do any modifications to the torch or fittings. might want a steel plate and a peen hammer to flatten it out if need be.
