- Bob, what are we doing today buddy?
- Man, I'm feeling a little frisky how about,
how about some metal core work in the groove.
- One G?
- (beep) please. I've got two G.
- Nah. I bet you lunch.
- Bring it.
- All right, let's do it, let's see it.
(machines being set up)
- All right folks, you heard him, he chirped again,
I'm feeling hungry so I want a little free lunch
out of this guy.
- Bob, I have all I ran it was on 75/25 one G.
- You've done all your stuff flat?
- Yes sir.
- It'll run, it'll run horizontal a lot of it,
I've actually even done some overhead fillets
if you can believe that.
So, this is Select Arc 70C metal core,
928, we're gonna go 27 and a half volts,
450 on the wire feed speed
my attempt here is just gonna do a single field pass
I'd like to do a two bead cap,
but I might have to run at three
'cause I'm not recognizing this bevel angle
it looks a little more than 30 to me
so you know, I'll recognize it.
And as a bonus, how about
we cut and etch a couple of samples here.
- Alright I'll do the cutting and you do the etching.
- Alrighty. Let's do it.
Hey Mike, I've got some coupons
that I played around with here
and I went ahead and did the hardwire route,
so we're gonna, we're gonna like,
spray this in here,
single pill pass, you know that J move I was showing you
on that aluminum when we were
doing that overhead spool work?
(electricity fizzing)
- Yeah I can do it.
- The J move, well I'm gonna use it right here.
What do you think of that?
- All right go use it, 'cause I can't do it.
- Strap in, cupcake.
- [Mike] Let's do this.
(electricity fizzing)
- [Bob] You know, as we're doing this subtle J
'cause I like to fill this topside a little more
than the bottom. I want that shelf
so I can set my first path on it.
And I don't want a deep, deep groove up here at the top.
I just wanted to get, you know,
otherwise I'm carrying a bunch of metal
and that's where I might get undercut.
Kinda where I've done before.
So very subtle J, just kinda
like polish the top, you know.
You know, the J move. - [Mike] Yeah I see it.
- [Bob] The signature.
- [Mike} I see it.
- [Bob] All righty, let's buff this rascal out.
(grinder noise)
All right, we did a little light buff here,
I missed this on the start of it, but,
when I got into my pattern and got comfortable
I tried to slightly overfill this top,
leave the bead profile and then work flat,
but I wanted this shelf in here,
'cause I intend on running the wire here.
Like right here, and I'll be watching the bottom of this
to make sure it's melted out
and I get some reinforcements started.
Again, I haven't decided whether I'm going three bead.
I'd like to do two bead because, I mean,
it should be able to do it.
Anyway, we'll pull the trigger and do a fill pass in here.
- All right.
- How's that,
how's that free lunch feeling right about now?
You, are you getting close to realizing
that we run metal core here?
- I'm basically realizing that, okay
I'll get my wallet out and pay for it
(laughing)
- We'll see.
(electricity fizzing)
Got a little crater at the end, kinda unavoidable,
I needed to run off tab or something,
but I'm watching this crown along the bottom
and I'm trying to fill it quite a bit
'cause again, I'm attempting to go to a a two bead cap.
So I want to use this part of the bead
and I've gotta get all the way up to the top.
Very slight, I don't know if you're watching that,
but it was like a very slight pause
in order to make this thing build to where I kinda want it.
I wasn't using a big motion,
I wasn't whipping and dodging and bucking and weaving.
I just gonna
- [Mike] Yeah, and nice and tight,
you're going
- [Bob] Going tik tok. A little tik tok.
So anyway, hopefully we've got a profile in here,
I'm pretty sure I can get to it with a two bead
without having to cut it and go to a three bead.
I want to buff this off clean it up a little bit
so I can see this top edge real well.
What are you thinking you wanna buy me for lunch?
- Arbies?
- That's fine. I can work with it.
- You want a Ruben Cuban?
- A Ruben sounds good.
- Some curly fries with some mango tea or something?
- Yeah. All right, keep that in mind.
(electricity fizzing)
Oh my goodness
- [Mike] That looks pretty good dude.
- I am hungry. I don't know if you noticed but
you know a lot of these hot processes I try to go
a couple of degrees forward.
But this one here on this last pass
I kinda, I went in straight, kind of changed it up
just a little bit, just a hint of dry gambling
because I'm trying to avoid
any kinda undercut, on top.
Again, we went to this two bead thing, so
very slight technique, it's just a, a pause here
I wasn't doing the big rocking motion
or weaving, stepping and bobbing and all that stuff.
All right Cub, you chirped, I delivered,
I think there's a lunch involved here.
Go get my lunch.
- [Mike] All right I'll go get your mocha.
- [Bob] I'll have this cut and etched
when you get back we'll show some samples.
- [Mike] All right.
- [Bob] It'll be nice and tight, yeah?
- [Mike] All right.
- [Bob] Appreciate you. You learn anything?
- Of course I did.
- You know I did too.
Hopefully the viewers did, thanks for watching Weld.com
please check us out on Facebook and Instagram,
Cub's gonna go buy lunch.
(electricity fizzing)
(grinding noise)
(buffing noise)
(bags dropping onto floor)
- I still don't think you can run that overhead.
- Next week.
- All right.
- It's on.
