- Welcome to Weld.com.
I'm Bob Moffat.
I got the Cub here today, say hi Cub.
- How you guys doing?
- What is all, yeah we'll
talk about that later.
- Hey you see, I started this first.
(laughs)
- Did you really?
I started this like a week ago.
Anyway, hey we got a request here,
multiple viewer comments,
we're also going to test a different wire,
that I mean something we
haven't run before brand wise.
But we got to do some overhead
filets with flux core, okay?
- Mm-hmm.
- 045, you in for that?
- Yeah.
- Okay, we'll do the
three pass type thing,
where we're running courses.
We could run more
courses of beads in here.
But again it's that stack, you
run the first one in there,
second one goes on the
bottom, third one on top.
We're trying to maintain that profile.
I have prepped some plates for you here.
The top plate is slightly longer.
I've tacked over here.
I didn't do anything in the
center of the weld area.
So you should be able to start,
bump into this tack right here
and come out to the
end and not blow it up.
Actually you're right handed,
you'll be welding this way.
Okay so first question
is, do we push or pull?
- You drag.
- Okay, its got slag.
- You drag always.
- You drag.
- Okay, good thought.
- What angles do we run on that drag?
- Well you know that's a consideration.
A lot of people think you really got to
add a whole bunch of angle.
You're going to be welding
this direction, toward me.
- Mm-hmm.
- Right handed, so you
want to point it back.
I kind of like, you know,
this is straight in.
I kind of like this 10 degree
back just a little bit.
You can see where you're going,
you can see you're finished
weld pool in-front of you.
- All right.
- Make sense?
- Yeah, but what is this,
your transverse angle?
Thought the transverse
angle would go in this way.
- The wire angle end of the
joint you mean, this way?
- [Cub] Yeah.
- Oh I would treat it at a 45 into this.
- [Cub] 45?
Gotcha.
- Yeah.
- So we're going to be
running 045 select-arc
730 carbon steel wire.
It's designed to run mixed gas.
So we're running 75/25,
about 25 cubic feet per hour.
What do you like for settings here?
Do your settings, do you change stuff up,
whether you're going over head, vertical,
horizontal, horizontal in a groove?
- Yeah, I change stuff up from vertical.
- Drop and what, volts
and wire speed or just--
- I turn wire speed up more,
and volts a little bit down more.
- Personally, I just tend
to drop a half a volt
or volt and leave the wire alone myself.
- Leave the wire alone?
- Yeah.
One thing that is
critical, I think anyway,
this wire should be really forgiving,
and it should run exceptionally well.
But keep in mind electrical stick out.
Flux cords like a little longer stick out
than what we normally run
on gas metal arc welding,
short circuit or globular.
- What's that stick out?
- I like to keep mine
5/8 and three quarters.
- 5/8 and three quarters, alright.
- You know, what's the
worst thing that can happen?
Piping porosity, volt sensitive
wires, leave those little
tracks in the face of
the weld beam and that's
annoying really, but--
- All right, well how do we
know if we are too close?
What's going to cause that?
- Same thing, you can
actually get worm holes
by running your nozzle up
real close, real short.
- Gotcha.
- Shouldn't, but again,
you know, just keep that
out there about 5/8ths or so.
- All right.
- See what happens, we're
not trying to run anything
exceptionally huge, you know,
the face of your weld should
be what about 5/16ths, 3/8ths wide.
- As thick as the plate,
a little bit bigger than
the thickness of the plate, yeah.
- I mean, I'm talking about
the face of the weld, how
you judge for the size of your bead.
- The size of your bead, so--
- We don't want to run
too small of a bead on the
first one and then try to stack two great
big beads in there.
- Yeah, overlapping sizes--
- We want to run them
all pretty much normal,
same size and everything.
- So you run 5/16ths you were saying,
for speed, second and third?
- Yeah, just to see how it goes.
Again, this is going to have
a slag around the weld pool,
you're not going to be able
to see real sharp lines on
where your pool is, you'll
see the edges quite well,
but you won't see the back of it.
Like pouring butter up into
your, you'll be all right.
- Cool.
- You'll be all right.
- All right, cool, we
going to cool this down
after each pass?
- We can, we can, we've got
a coupon cooler over there
that I built for you.
- Yeah it rolls around pretty good.
- Yeah, it does.
(laughs)
- Good, good.
- All right.
- All right, let's do this.
- All right there young man.
I've got you set up at 26.5 volts and
450 on the wire fuse speed.
- You want my gas turned on?
- I do this time, yeah.
You can go ahead and pull that trigger
and check it if you want.
- I'm going to do a
little dry run and make
sure I can get comfortable with this.
- All right, wait a minute, time out.
While you're doing the
dry run, you're sitting
here and changing your
gun angle, wire angle.
- All right, how can I--
- You need to, if you start out
minding the 10 degrees right here,
then you need to maintain the
10 degrees all the way across.
When you come over here,
come to this edge right here,
and pull it back through slightly.
Worse thing you can do is come out here,
stop, and leave a big old crater and blow
this corner up and undercut.
- All right, I'm bad at doing that, yeah.
- Yeah, yeah, so, now
when you, bring the weld
all the way out, when you
come over here to the edge
don't increase your speed like
I'm going to jump over there.
Just come over here and pull it back
through about 3/8ths to a 1/2 of an inch.
But try to maintain the same
wire angle all the way through.
And you're changing it again.
- It's hard, it's going to take practice.
What if I can stop half way, restart--
- No, we don't want to do that.
- All right.
- It's just not a, hey, you don't have to,
can you use the bottom of
this plate to glide along?
- Oh, yeah.
That's perfect.
- Well what's wrong with that?
Get comfy there.
- All right.
(electrical hissing)
- This wire looks good,
I already can tell.
(machine whirring)
- That better?
Slag came through it.
- Your slag fell off in
one piece on the floor.
So I don't have to do much,
I was going to be your
boy over here and take
care of your weld and
clean it up for you so--
- Yeah, we love that.
- Very little spatter,
I think this wire runs
extremely smooth.
- [Cub] Oh yeah, I just
noticed that, yeah, wow.
- [Bob] It looked like you
changed your angle and slowed
down over here while I
was watching you, but it
doesn't show that in the weld.
So, if you want to say
the wire is forgiving,
there you go, that's part of it.
But I thought the weld profile, it varies
a little bit, it's a
little bit wider here.
I still like, you know, coming out,
you pulled it back here
and then you went back
toward the edge of the plate again.
- [Cub] Don't do that?
- [Bob] I wouldn't.
- [Cub] Okay.
- [Bob] Now we are
building up a little bit.
The main thing is you're okay.
You didn't blow up the corner.
- [Cub] Like last time.
- [Bob] That's what we don't want, okay?
You could always come in here and
reach in here and touch
that with a grinder
but you know, now we have
a good spot to end on,
because the next weld that we
run, we are going to run at the
toe of the weld on bottom.
Okay, we are going to blend this together.
We are going to come
across, when we get here,
do the same thing.
- [Cub] All right.
- [Bob] Pull it in, when
you start, start right here,
bring it out and then kind of
wash through it a little bit.
It'll make the corners wrap.
- [Cub] All right so about
a quarter inch, ahead of
this corner right here.
- Yeah, when you pull
the trigger, you move.
Pull the trigger, you initiate
the arc, go to the corner,
wrap it around an end,
come into your run, okay?
- Gotcha.
- You're only welding into
the little bit of your
weld pool and it's going
to, it'll be all right.
- I'm always scared I'm going
to trap slag inside there.
- No, I've not seen that,
not in wire welding,
not in structure welding.
(machine whirring)
- [Cub] Oops.
- Yeah.
(laughs)
- I was trying to--
- Well, see that's what
I'm saying, you get
out there and--
- You got to be fast.
- You got to be a little quicker, yeah.
We are talking 26 and a half volts,
you're depositing some material.
Put your gun back up
there and show me where
your angle was and--
- I know, I started pushing it.
- That's not what I said, take your gun,
put yourself in the same position.
I want you to see this.
- I got to cut my wire first.
I was like right here.
- You got to do more than that.
- I was like right here.
- No, it looked like
you were like over here.
And that's a push angle just the opposite
of what the 10 degrees over here.
- Yeah.
- Hey, the wire is forgiving.
You got 20 degrees you're
playing around with here
and you're still making an
okay weld except for this.
- Well the flag was already dropped off.
- [Bob] Nodular deposit over here.
- [Cub] Nothing the grinder couldn't fix.
- [Bob] Who wants to grind?
- [Cub] Not me.
- [Bob] I don't either.
- [Cub] I was too slow right here too.
- [Bob] If you look down through here your
profile is okay and you kind
of see an arc in your bead.
I mean, and you're slow to start.
- [Cub] Yeah you're faster.
- [Bob] Yeah, I mean if you
were doing the entire run
I'll have to get
critical, but you know the
center of that's got a
little shoulder to it but--
- [Cub] You think move faster?
- [Bob] Well think about it.
- [Cub] So I can move
faster or let it cool down,
one of them two options.
- [Bob] Fast accurate start,
it's like stick welding,
you got to be accurate with stick, right?
- [Cub] Yeah.
- [Bob] You got to put it
in there, initiate the arc
get it in there and go, same thing.
Pull the trigger, make
a move, and come out.
- [Cub] All right.
- [Bob] When you come out
here at the end, just wrap it
pull it back through.
- All right.
You can't sit here for
two or three seconds.
- [Cub] And lolly gag in my head.
- Otherwise you're going to
be reaching for a grinder.
- Like right now.
- You are, not me.
(laughs)
- Let me fix that.
- I'll hand it to you but--
- I'm going to fix that, all right?
- All right.
(machine whirring)
- That better?
- Much better start, much better finish.
- Thank you, appreciate it.
- There's your slag old bud.
- Thanks.
- [Bob] Reached up here and you
ground this finish lot quicker,
what'd you learn over here?
- [Cub] Learned about the
start, start a quarter inch in--
- [Bob] Yeah, you don't
whip it around but--
- [Cub] Be fast.
- [Bob] But you pull
the trigger and you move
just do it cause you
can't wait around again
you're laying down material
when you pull the trigger
045 wiring, 26 and a half
volts, we're not playing.
- [Cub] Yeah I can tell.
- [Bob] Okay.
- Don't mess around.
Get in, get out.
- Nice little wrap there so if you started
doing that on every pass
what would you end up with?
- Nice consecutive start and finishes.
- Right.
- And then--
- If you have to make super long runs
and you got to stop and
just move your machine
or you got to do something,
get comfortable, always
try to stagger your starts.
- Oh yeah.
- Lay them in at an angle or something,
so they just look nicer when you do that.
- Yeah.
- Especially in horizontal runs,
multiple stringer build up,
tilt welds and all that.
- Gotcha.
- All right, nice run and
I hope this answers the
viewers' comments, you know
we can take this, I'm real
certain we can take these
settings and run multiple
settings in grooves, right?
- Mmhmm.
- 'Cause the wire's going
to stick up under there,
it's going to stay there.
It looks funny doesn't it
'cause you can't see your weld pool.
- Yeah.
- You really got to
trust it 'cause this wire
has that slag around it
but if you stay in the weld
pool and don't flinch it'll stay there.
Seems like some people
get to manipulating it
or they jump forward or
something, it gets narrow,
sags, peak it, if you just
leave it in there I mean,
look at this profile right here.
Nice consistent bead width, good stack.
- [Cub] You just want to stay
consistent and stay straight.
No whipping, no side to side pause.
- No need for it.
- All right.
- Just, I do a slight tick
tock cause I got to move
just to move but--
- Gotcha.
- It's slight.
And it doesn't matter because
this doesn't have the
ripple pattern to it,
it's not going to see it anyway, but--
- All right, sounds good.
- But I hope this satisfies the viewer.
I certainly learned a lot
from you, from your starts
and stops.
- What not to do.
- Well no, no I am not saying that.
- Brought back the good memories, huh?
From when you started.
- Get those stops and
starts down, you know.
Pull the trigger and move,
when you come out here
at the end, don't lolly gag around.
Just pull it out and get it done.
Don't leave a big old button on there.
- All right.
- Hope you found this educational.

The man cub.
- Thank you, appreciate it all.
- Yup, yup, thank you so much.
(laughs)
- No bake cookies.
Got to get close now man.
- What am I stepping into over here?
You fart, you farted, didn't you?
Oh, god.
Well before you start why don't you
cut your wire off one more time.
I was just joking.
(laughs)
- I had to take it to
the next step brother.
- Oh my goodness sake,
are you serious with that?
- Cut that five and a half times?
Six, oh man that's perfect.
- What is perfect?
- I know it's perfect.
- So you're reaching for your, why?
(laughs)
Cub, get some work done.
