hey welcome to welkom had a lot of a lot of comments people getting into flux core and
you know the flux core self shielded dual shielded today what I'm going to do a quick lesson here and
get some folks started we've had a lot of requests how do I get into this but you know the settings
of the wire and everything so I want to explain a few things and just keep it real simple I'm gonna
go through a bunch of settings just want to run some straight lines flat position get into some
things to look for get you started today we are running select dark oh four five seven thirty
dual shield flux core wire designed to run on mix gas 75 25 and I'm gonna be running about 25
cubic feet per hour we're gonna be running off of it an eSAB to 85 that has various modes in
here right now it's set to s MIG and I'm going to take this and run it up to the flux core and
select that I'm gonna set this at 26 five volts twenty six point five volts 450 on the wire feed
speed that's going to be kind of my baseline and I'm gonna run a series of straight beads and just
see how everything reacts I'm gonna start here at this base point because this is real close
to what the manufacturer recommends for settings and then from there I'll ruin the settings I'll
go way low and voltage leave the wire feed speed alone will just change up a lot of stuff and see
how the Machine reacts so that's gonna be our starting point twenty six point five volts 450
wire feed speed also one thing to note is this is a gas shielded wire it's kind of like running
any hard MIG wire your polarity is dcep on hard Maguire gas shielded flux core wire dual shield
if you have self shielded wire whose self shielded wires run on dcen electrode negative okay one that
it's very important to remember I found a dummy plate over here and I'd rant there was a groove
weld that somebody had set in their machine that looked like ran a big wide route for gas metal
arc welding had a past couple passes in there I went ahead and filled this thing up with the
flux core ran a couple of stringer beads in here and so now I want to take this and start running
beads away from these here so I always want to run straight beads I use the groove as a guide
so therefore these two stringer beads are pretty straight if you have a hard time seeing then you
can come in here and kind of put a chalk marker in here get some contrast after you run a couple
of beads probably won't need this anymore simply because we're gonna be out here on this plate and
it's gonna round up a little bit and you'll always be able to put the wire in the toe of
the previous weld which is important for running straight lines and running straight beads so we
can cheat a little bit and run a little soapstone in here so that we're when we're under the hood
we might be able to pick that contrast up better this side does have more of a toe than this one
here okay I have never been one to to teach or to have people well pulling the gun toward themselves
or any I like to be able to I'd like to be able to move so I'm going to turn this to the side a
little bit I like to see where I'm going and I like to see my finished weld flux core dual
shield I want to drag this slightly I want to put about five to ten degrees of drag angle in
here so I'm gonna start on my right side and weld in that direction so this would be a drag angle
this would be a push angle okay so I want to use a slight drag angle I also I don't want to get
my hands in here close to the weld it's gonna put out quite a bit of heat so I want to hold the gun
back here I'm always wanting to hang on to a gun lightly anyway so I can move but I want to hang
on to the gun back here towards the back I don't want to get my hand in here where all this heat is
gonna be on the back of my knuckles because that's gonna it's gonna get uncomfortable quickly so I
want to stay back here and just kind of glide along okay real simple I want to run straight
lines I've got a soapstone mark along the toe of the web so first thing to do is get comfortable
always want to maintain your wire angle remember I said I was gonna have about a 5 to 10 degree
drag angle so I want to kind of set that first my wires sticking out about five-eighths of an inch
past the contact tip electrical stick out on dual shield but the core is more than regular short arc
short arcs about 3/8 of an inch bill shield you want about 5/8 to 3/4 so I'm gonna set the wire
over this toe of this weld and just kind of glide along and do a couple of couple of dry runs okay
you get comfortable I'm using my pinky I'm on this piece of sheet metal so I'm not gonna hook
my glove in the hole accidentally light pressure on everything for me and I'm just kind of want to
glide along here and see what happens well I might this first run here and as soon as I pulled the
trigger I couldn't see my white line I couldn't see where I was going I think I have my hood set
down to dark I think I'd have it on the number 12 but again I couldn't see my white line so I
made a little bit of an arc here my bad a good condition because this is the slag is already
cracked so really all I got to do is just kind of kind of touch it on the edges here and it'll come
right off I'm not wanting to beat the crap out of the slag because it can become airborne and
come right back up in your face okay now I have some place that I know I can see also if you've
watched our videos long enough you'll know that I'm can't move good just gliding along so this
next bead I'm gonna adjust the sensitivity in my hood so I can see a little better and I'm going to
position myself over here and I'm probably gonna just do a very small rocking motion so that I can
time my movements also another important thing is when I said get comfortable I'm just kind of
standing here some of you'll put a lot of weight on your forearm here and then you can't move so
you know I've kind of just Center in my weight down through here trying to relax stuff just
runs in so smooth it's so forgiving just pour it in there like butter it's pretty nice and believe
it or not this is one of those wires that you can well the horizontal uphill overhead it just goes
in really nice so we've run multiple beads here at the same setting 26.5 volts 450 on the wire feed
speed from here you know we can we can do multiple things here we can take the voltage and decrease
it we can increase the wire speed both of those will do about the same thing it'd be like really
shortening up the arc so let's just leave the wire feed speed where it is and we'll decrease
the volts by three we'll go from twenty six five down to twenty three five and see what happens
so I decrease the volts by three I was a twenty six five I went down to twenty
three five hopefully what you'll be able to see here is might be it's going to be a
shorter arc less fluidity of the weld pool and it may spatter and buck a little bit
but the only thing that I noticed happened was a little more spatter remember I said this wire
very forgiving slag is still coming up in chunks the weld stood up a little taller okay and we had
more noticeable hard spatter that came off of it but it still ran fine and the bead looks fine okay
but if we want to increase that effect then we would decrease our voltage even further so let's
just run it on down to another three volts and see what happens I don't expect it to run very well at
all with another three volts well it's trying to run I can tell you that and I'm pretty impressed
with what I'm seeing with this particular wire here three volt change and it still ran decent
it just had some hard spatter we're six volts off of our baseline at twenty six five I dropped it
down to twenty and a half it's still trying to run it's just it just doesn't have the voltage
to combust the wire and get fluid while I was running this and this is why I quit half way
through is because the the wire you kind of feel the wire just coming down and bumping the the
grounded plate so you know not a good condition and you can see why so now we can go back to our
baseline of twenty six point five 450 we can leave we could recreate this effect kind of on
the higher end and run way too much wire but I don't think we need to I don't think we need to
recreate that condition what we probably should do at this point is go back to our baseline at
twenty six point five leave the wire feed speed alone and increase the voltage but I don't want
to go by threes let's go up by volt and a half and show some effects what we should see is longer arc
wider weld pool so this bead here was a Bolton that half higher than our original twenty six and
a half now we're at 28 I noticed that the bead is wider and flatter definitely from what we just got
they're running too cold but from 26 v compared to this I notice it being wider and flatter from here
we can go up yet another boat in half and here's where I start getting I don't know I get a little
uncomfortable I don't like this too far out of out of balance here I think this is gonna be too wet
too wide too fluid I just I lose control in the flat position probably wouldn't be bad vertical up
horizontal I don't think I'd like this condition at all but I'm gonna try it so now we're at twenty
nine we're three volts above where we had started at twenty six five and I said that's why I keep
saying this wire is very forgiving we went low it still ran by three volts and now we're three
volts above and it did exactly what we thought it was going to do its wide and it's fluid and under
certain conditions you may want this so you know again I'm not I'm not seeing any adverse effects
here I'm not seeing the wormhole porosity I'm trying to keep my electrical stick out the same
Wow so you know again find that baseline of where the wires kind of supposed to run
and you know run some straight line beads in there play with your settings somewhat go a
little at a time a little bit and voltage a little bit of wire feed speed all these
machines run different so find that find that spot in there where it's nice and smooth it's
not throwing out a lot of hard buckshot edges are wetting in nine so again I wanted this to
be kind of an introductory for those that are getting into running duel shield we are
running the Select arc 7:30 o for five runs extremely well so I hope you found
