Impressive. You're a magician.
It's easy after the first few. When I started doing it though I didn't believe it was even possible. Here's a few more, I want to take more tonight if you guys don't mind. Try to get the full idea at least of how we do it.
You can kind of see the opening in my root here. On this one I fed him the filler wire through that opening for the bottom section
It's a little tight. There's wooden wedges holding that gap at the bottom. Once it's done we move them to the other side, then for stick just try to find a middle ground.
The last 2 were horizontal, this is a quick shot of the top weld. I meant to be farther back for this shot.

Regulators don't typically fail the way you describe. I expect the hose has a leak at a fitting or the torch leaks but the regulator back has a vent that can be tested. Some soapy water makes a good leak detector solution. If you aren't familiar or have not recently read-up on acetylene-oxygen safety, here is a good link: http://www.esabna.com/euweb/oxy_handbook/589oxy1_1.htm
The hose connection wasn't leaking. I always test the hell out of everything with soapy water after changing a tank. It was leaking out the vent holes around the regulator knob. When I couldn't get a reading with soapy water on the fittings, I turned off the main valve, let most of the pressure bleed off, then explored with a lighter. I got some small flames out of the vent holes. Before anyone freaks out and tells me how the tank could have exploded, consider that the main valve was shut off & any O2 had been purged out of the hose. Still, I had an extinguisher handy. Better to find the source of the leak in a relatively safe manner than to risk having my entire house explode.
I'm told that if you forget to back off the regulator and turn on the main valve, the sudden surge can damage the diaphragm. This particular regulator was a Taiwanese Victor knock off that was 25 years old. The O2 companion failed in a similar manner 10 years ago.
Back in welding school, our instructor had the bright idea to have a timed competition in swapping tanks. You had to remove the old tanks, put new ones in place, and light a torch. One torch lighting ignited a small leak from a acetylene regulator. While the students leapt out of their seats and started for the door, the instructor calmly leaned over & blew out the flame.
Welp, second career time. As soon as my paperwork gets done, I start with Fundamentals of Welding on Jan 7th. I've had informal welder training (learned to MIG in a buddy's garage, took some voc classes in Missouri), but now I'm going as far as I can, gonna collect as many certs as I can get.
I hope you are young and agile.
Not young (41) but agile.
Eyes still really good?
Learn how to put a bead in w/tig and walk the cup.
Get good with that tig torch, bead, fill, and cap.
anybody can run a stick.
Contact lenses. 2 years ago, I could lay a bead in steel & aluminum with a tig. Haven't practiced since, & never learned to walk the cup. In the program I'm in, they want you to get advanced certs in two of the three disciplines. Tig will def. be one. The other will be whatever has higher paying jobs.
don't let them fool you with those "certs" and starting salary BS. I own a welding shop. we send people away every day who have "all the certs" who cant even pass our basic weld test. lots of people go to tech school with the best of intentions and I feel the school's rob them blind. we have 50 guys on the floor and I would say 1/8 of them came from the local welding schools. the rest were self taught or went to school so long ago that nothing they learned applies anyway.
to a shop welder "certs" mean nothing. I explain it every day. you have to qualify to our process from ASME before you can weld on anything in our shop, same as any other shop. just because you have a certificate that says you can weld to ASME section 9 specs doesn't me you can weld on a pressure vessel in our shop, for that you have to pass our weld procedure tests that have been approved by ASME. then you get your stamp and all the paper work that goes with it.
sorry to soap box but the whole trade school thing has me up in arms lately as we really need people and we cant find them. I could hire 10 guys right now but the quality is just not there. we get better kids right out of the tech high school then the almost 30G post secondary school.
and as for pay, when they tell you that you can make a 100G a year what they forget to tell you is to make that you have to 1-know what your doing 2-be willing to work outside in less than ideal conditions 3-be away from home a lot 4-buy a $50,000 truck 5-buy a $10,000 welder and its accessories 6-buy at least a million dollars in liability insurance.
I agree on just having random certs. Most are good for on a particular machine and going to another shop means you would have to re-cert. No point in getting certs for stuff you aren't going to do as they expire and you've just wasted your time and money.
By all means, soapbox away. Just bear in mind, like I said, I'm 41. This is not my first go-round at the rodeo. I have a better idea than some kid what I'm getting into, despite my inexperience in this particular field.
Even despite your warnings about having the knowledge despite the certs, nobody will even look at you unless you have the certifications. I read job descriptions well enough to have gotten the idea that you will have to prove your paper.
As for pay, I know there's lots of jobs out there, with a variety of requirements and a variety of pay grades. And though my hopes are high, my expectations aren't. But my girlfriend has the type of career that's very specialized - she has to go where there's work. And I have to land with my feet on the ground ready to work.
If you really are having trouble finding welders, try Missouri (where I originally trained). They have a lot of training programs producing good welders who don't have jobs.
About 7 years ago I did a job that included 164' vertical up 3/8" fillet. They were 4 foot gussets on a Cell tower. The job took about a week and many rolls of wire. When finished, I called the CWI and took an AWS 3G bare wire test. I passed and its the only cert I have. It has got me a few jobs. I am asked for it about once a year. I own a welding shop. I am NOT a rig welder. I make a living. Nothing more.
Saying I am a certified welder is like saying I am a Diesel Mechanic. Neither is important unless I can do the work. I have seen some 3G work done by a guy certified in 3F. It was absolutely terrible. Maybe he has the paper, but he is not a good weldor.
Around 41 I started switching from auto/truck mechanic to weldor. Both are good ways to make a living. I did this because my son took welding at boces and 2 years at Alfred State. He is now 22 and works with me.
Learn the skills. Learn as many process as you can. Don't breathe the fumes. Pass the wiz quiz
It took me about 5 years to become a good tig weldor.
Best of luck. Its a new adventure no matter how you look at it.
I was not directing my soapbox right at you sorry if I offended. I had just got out of a 2hr meeting about personal when I happened to read your post.
good on you for getting training in a field that allows you to hit the ground running wherever your girlfriend drags you. hope she's hot, because the welding sparks that land on your nuts and your boots sure are!
No offense taken. I'm pretty hard to insult. Besides, your soapbox-ing was pretty educational. Thanks for your insight. If you've got any more tips, don't hesitate to let me know.
Oh and she is hot, and no, I won't show you pictures.
this is all entertaining for me, because my employer LOVES sheepskin qualifications. im not sure how a degree in marine biology would make a better cop, but when I compete for a promotion, id be better off if i had a bachelors degree. I like to tell them "but I got a welding certification... in alaska, in 1995!. And I have 14 years on the street, as a cop. which am I better at?"
Sometimes I would love to be a welder. Go for it! do what it takes to learn how to do it well, and the certifications will probably just come from the training.
Alright, my turn for a question.
After a few years of lots of MIG work, I'm about a month into teaching myself to TIG. I've noticed the Forney auto darkening helmet that always worked marvelously for my MIG work isn't cutting it with the TIG. I don't know if it's just getting old (internal battery shitting out), isn't sensitive enough, doesn't have enough sensors, or what, but when welding, it only stays dark about 75-80% of the time without flashing. No flash burns yet, but it makes it very hard to lay a good bead.
What do I look for in a decent (read; not overly expensive) helmet for TIG'ing? Any specific models to look for? A new helmet is on my Xmas list, but I need to tell the fiance what make/model to get, less she buy me a non-auto helmet with flames on it
Anya cheap helmet I have used flickers with TIG. I use a miller Elite, there are many others.
If you have a Northern Tool nearby, or will buy other tools to save on shipping, I can recommend the helmet in the link. You can spend much more and considerably less for a helmet. Good luck!
x2 one of these suited my budget so I bought one after Stan's recommendation & I've done a good few hrs behind it now. I really like it. I had to do a minor bodge on the headgear to get it sitting right but otherwise it's been great. The big window is a real nice thing to have.
