Now, before I put the gas on it or in it, I'm going to make just one tack weld to hold it together in place.

A

Now your settings on your welder are going to vary with the welder and it just takes experience knowing what your welder will do and how it performs.

A

Tig welder is always AC or is it tick? Tick is a see ya. Uncle Denny see you. Could you can well TC, just beautiful welding. Don't have enough experience to say well, do this for this and then to this know what I've done in this shop. Of course, this welders.

A

A

Will say you want somebody with experience welding these together, because if you don't you're going to have problems- and we will pressure check these, what I do is I weld about three or four of them together and then we press your check them and and I run these up to 3,000 psi, and then we bang on them with a hammer and throw them around and do whatever we can to try to destroy that weld and that's how we test our welds. Okay, there are more advanced methods of doing it.

A

Like ultra, you know, ultrasound and x-ray and stuff like that, unless you're building a nuclear reactor wouldn't worry about it too much, we just need to have a good, solid, well to make sure it doesn't leak. So all right, I'm going to turn this on.

A

It's just standard 308 rod.

A

Welding helmets have one with an auto darkening land, it's more efficient, because you can actually see what you want to well before you start the art and it will help you. It just makes it a lot more times less time-consuming and have a new than having to flip it down with your heads. Well, then, your hand moves, so these are quite nice to have this one costs like a hundred twenty-five dollars.

A

We can get hotter by pushing that pedal all the way down cooler by backing off. We also have a manual adjustment up there, there's three lines going to that. What's going on, there's coolant going in and coolant going out. Oh that's a coolant line and you're a new, your inert gas, oh yeah! This thing will be glowing red, hi, where's, the power to this see the cord.

A

Let's combine coolant and power cord yep. Well, no, the coolant is its own entity. The power cord is in the gas line. This then just little metal strands. Yep the line has little metal strands in there. What voltages this dude's money? It's got to be high because you can make it this. This can be set up for 44 4220.

A

You don't need a ground. You need the ground. Yeah I got to put the ground; okay, otherwise, that won't be all right, won't get any flame. I'll put it that way.

A

Oh wow so cool. So what you do is you heat up the metal and you feed the rod into it. Yeah, that's nice love. It I've been having some problems, so this is high-voltage on. Unlike the mega mega is pretty low.

A

Just your whole body, butter is just a little bit. Okay,.

A

This is more or less held together. I mean it's, not it's not burn, but we can. We can take that block law as penetration. Okay,.

A

We can set it up like this, but before we continue welding, we have to put that inert gas in there, because I blew a little hole in that I did blow a little hole in that when I was just tack welded at night, but it wasn't enough I back off soon enough to fill the hole shouldn't have caused any kind of walking.

A

Now wish we had another tank of gas.

A

But we don't so I'm going to have to keep tables opposed off the mig welder and then reconnecting it.

A

As as we cut and weld our spacers in between the coil.

A

This might be better if I put that welder over there.

A

Let's just move this.

A

Not being charged so they're, probably not emitting any explosive gases but better safe than sorry. So it's nice to have a scrap in handy.

A

A

And you know what we have to pay, somebody to all that stuff away.

A

A

Take it all down to the.

A

Hill cost farm and put it in a dumpster there and they come and haul it off. Every so often metal, scrap yep.

A

We do generate quite a bit of metal, strap just a lot of these mobile pieces of equipment that are worn out and don't in there on serviceable.

A

This will keep our line.
